5 | 60 | Adrian Georgescu | This chapter describes the event driven ''Middleware API'' that can be used by a developer to build a user interface for SIP SIMPLE client SDK. |
6 | 14 | Adrian Georgescu | |
7 | 54 | Adrian Georgescu | * For sub-systems communications the Middleware uses the [http://pypi.python.org/pypi/python-application/ Notification Bus] provided by [http://pypi.python.org/pypi/python-application/ python-application] |
8 | 49 | Adrian Georgescu | * For configuration the Middleware uses the [wiki:SipConfigurationAPI Configuration API] to access General and SIP account settings |

12 | 64 | Luci Stanescu | == Lookup support == |
13 | 64 | Luci Stanescu | |
14 | 64 | Luci Stanescu | The SIP SIMPLE middleware offers the {{{sipsimple.lookup}}} module which contains an implementation for doing DNS lookups for SIP proxies, MSRP relays and STUN servers. The interface offers both an asynchronous and synchronous interface. The asynchronous interface is based on notifications, while the synchronous one on green threads. In order to call the methods in a asynchronous manner, you just need to call the method and wait for the notification which is sent on behalf of the DNSLookup instance. The notifications sent by the DNSLookup object are DNSLookupDidSucceed and DNSLookupDidFail. In order to call the methods in a synchronous manner, you need to call the wait method on the object returned by the methods of DNSLookup. This wait method needs to be called from a green thread and will either return the result of the lookup or raise an exception. |
15 | 64 | Luci Stanescu | |
16 | 64 | Luci Stanescu | === DNS Lookup === |
17 | 64 | Luci Stanescu | |
18 | 64 | Luci Stanescu | This object implements DNS lookup support for SIP proxies according to RFC3263 and MSRP relay and STUN server lookup using SRV records. The object initially does NS record queries in order to determine the authoritative nameservers for the domain requested; these authoritative nameservers will then be used for NAPTR, SRV and A record queries. If this fails, the locally configured nameservers are used. The reason for doing this is that some home routers have broken NAPTR and/or SRV query support. |
19 | 64 | Luci Stanescu | |
20 | 64 | Luci Stanescu | ==== methods ==== |
21 | 64 | Luci Stanescu | |
22 | 64 | Luci Stanescu | '''!__init!__'''(''self''):: |
23 | 64 | Luci Stanescu | Instantiate a new DNSLookup object. |
24 | 64 | Luci Stanescu | '''lookup_service'''(''self'', '''uri''', '''service''', '''timeout'''={{{3.0}}}, '''lifetime'''={{{15.0}}}):: |
25 | 64 | Luci Stanescu | Perform an SRV lookup followed by A lookups for MSRP relays or STUN servers depending on the {{{service}}} parameter. If SRV queries on the {{{uri.host}}} domain fail, an A lookup is performed on it and the default port for the service is returned. Only the {{{uri.host}}} attribute is used. The return value is a list of (host, port) tuples. |
26 | 64 | Luci Stanescu | [[BR]]uri:[[BR]] |
27 | 64 | Luci Stanescu | A {{{(Frozen)SIPURI}}} from which the {{{host}}} attribute is used for the query domain. |
28 | 64 | Luci Stanescu | [[BR]]service:[[BR]] |
29 | 64 | Luci Stanescu | The service to lookup servers for, {{{"msrprelay"}}} or {{{"stun"}}}. |
30 | 64 | Luci Stanescu | [[BR]]timeout:[[BR]] |
31 | 64 | Luci Stanescu | How many seconds to wait for a response from a nameserver. |
32 | 64 | Luci Stanescu | [[BR]]lifetime:[[BR]] |
33 | 64 | Luci Stanescu | How many seconds to wait for a response from all nameservers in total. |
34 | 64 | Luci Stanescu | '''lookup_sip_proxy'''(''self'', '''uri''', '''supported_transports''', '''timeout'''={{{3.0}}}, '''lifetime'''={{{15.0}}}):: |
35 | 64 | Luci Stanescu | Perform a RFC3263 compliant DNS lookup for a SIP proxy using the URI which is considered to point to a host if either the {{{host}}} attribute is an IP address, or the {{{port}}} is present. Otherwise, it is considered a domain for which NAPTR, SRV and A lookups are performed. If NAPTR or SRV queries fail, they fallback to using SRV and A queries. If the transport parameter is present in the URI, this will be used as far as it is part of the supported transports. If the URI has a {{{sips}}} schema, then only the TLS transport will be used as far as it doesn't conflict with the supported transports or the transport parameter. The return value is a list of {{{Route}}} objects containing the IP address, port and transport to use for routing in the order of preference given by the supported_transports argument. |
36 | 64 | Luci Stanescu | [[BR]]uri:[[BR]] |
37 | 64 | Luci Stanescu | A {{{(Frozen)SIPURI}}} from which the {{{host}}}, {{{port}}}, {{{parameters}}} and {{{secure}}} attributes are used. |
38 | 64 | Luci Stanescu | [[BR]]supported_transports:[[BR]] |
39 | 64 | Luci Stanescu | A sublist of {{{['udp', 'tcp', 'tls']}}} in the application's order of preference. |
40 | 64 | Luci Stanescu | [[BR]]timeout:[[BR]] |

100 | 62 | Luci Stanescu | == High-level audio API == |
101 | 62 | Luci Stanescu | |
102 | 62 | Luci Stanescu | The high-level audio API hides the complexity of using the low-level PJMEDIA interface. This is implemented in the {{{sipsimple.audio}}} module and contains the following components: |
103 | 62 | Luci Stanescu | * IAudioPort: an interface describing an object capable of producing and/or consuming audio data. |
104 | 62 | Luci Stanescu | * AudioDevice: an object conforming to the IAudioPort interface which describes a physical audio device. |
105 | 62 | Luci Stanescu | * AudioBridge: a collection of objects conforming to IAudioPort which connects all of them in a full mesh. |
106 | 62 | Luci Stanescu | * WavePlayer: an object conforming to the IAudioPort interface which can playback the audio data from a {{{.wav}}} file. |

160 | 62 | Luci Stanescu | |
161 | 62 | Luci Stanescu | === AudioBridge === |
162 | 62 | Luci Stanescu | |
163 | 62 | Luci Stanescu | The {{{AudioBridge}}} is the basic component which is able to connect {{{IAudioPort}}} implementations. It acts as a container which connects as the producers to all the consumers which are part of it. An object which is both a producer and a consumer of audio data will not be connected to itself. Being an implementation of {{{IAudioPort}}} itself, an {{{AudioBridge}}} can be part of another {{{AudioBridge}}}. The {{{AudioBridge}}} does not keep strong references to the ports it contains and once the port's reference count reaches 0, it is automatically removed from the {{{AudioBridge}}}. |
164 | 62 | Luci Stanescu | > Note: although this is not enforced, there should never be any cycles when connecting {{{AudioBridges}}}. |
165 | 62 | Luci Stanescu | |
166 | 62 | Luci Stanescu | ==== methods ==== |
167 | 62 | Luci Stanescu | |
168 | 62 | Luci Stanescu | '''!__init!__'''(''self'', '''mixer'''):: |

170 | 62 | Luci Stanescu | '''add'''(''self'', '''port'''):: |
171 | 62 | Luci Stanescu | Add an implementation of {{{IAudioPort}}} to this AudioBridge. This will connect the new port to all the existing ports of the bridge. A port cannot be added more than once to an {{{AudioBridge}}}; thus, this object acts like a set. |
172 | 62 | Luci Stanescu | '''remove'''(''self'', '''port'''):: |
173 | 62 | Luci Stanescu | Remove a port from this {{{AudioBridge}}}. The port must have previously been added to the {{{AudioBridge}}}, otherwise a {{{ValueError}}} is raised. |
174 | 62 | Luci Stanescu | |

247 | 1 | Adrian Georgescu | |
248 | 62 | Luci Stanescu | Implements a high-level application responsable for starting and stopping various sub-systems required to implement a fully featured SIP User Agent application. The SIPApplication class is a Singleton and can be instantiated from any part of the code, obtaining a reference to the same object. The SIPApplication takes care of initializing the following components: |
249 | 62 | Luci Stanescu | * the twisted thread |
250 | 62 | Luci Stanescu | * the configuration system, via the [wiki:SipConfigurationAPI#ConfigurationManager ConfigurationManager]. |
251 | 62 | Luci Stanescu | * the core [wiki:SipCoreApiDocumentation#Engine Engine] using the settings in the configuration |
252 | 62 | Luci Stanescu | * the [wiki:SipMiddlewareApi#AccountManager AccountManager], using the accounts in the configuration |
253 | 63 | Luci Stanescu | * the [wiki:SipMiddlewareApi#SessionManager SessionManager], in order to handle incoming sessions |
254 | 62 | Luci Stanescu | * two [wiki:SipMiddlewareApi#AudioBridge AudioBridges], using the settings in the configuration |
255 | 1 | Adrian Georgescu | |
256 | 62 | Luci Stanescu | The attributes in this class can be set and accessed on both this class and its subclasses, as they are implemented using descriptors which keep single value for each attribute, irrespective of the class from which that attribute is set/accessed. Usually, all attributes should be considered read-only. |

If any error occurs with loading the configuration, the exception raised by the {{{ConfigurationManager}}} is propagated by this method and {{{SIPApplication}}} can be started again. After this, any fatal errors will result in the SIPApplication being stopped and unusable, which means the whole application will need to stop. This method returns as soon as the twisted thread has been started, which means the application must wait for the {{{SIPApplicationDidStart}}} notification in order to know that the application started. |
264 | 62 | Luci Stanescu | '''stop'''(''self''):: |
265 | 62 | Luci Stanescu | Stop all the components started by the SIPApplication. This method returns immediately, but a {{{SIPApplicationDidEnd}}} notification is sent when all the components have been stopped. |

284 | 1 | Adrian Georgescu | === Notifications === |
285 | 62 | Luci Stanescu | |
286 | 62 | Luci Stanescu | '''SIPApplicationWillStart''':: |
287 | 62 | Luci Stanescu | This notification is sent just after the configuration has been loaded and the twisted thread started, but before any other components have been initialized. |
288 | 62 | Luci Stanescu | [[BR]]timestamp:[[BR]] |
289 | 62 | Luci Stanescu | A {{{datetime.datetime}}} object indicating when the notification was sent. |
290 | 62 | Luci Stanescu | '''SIPApplicationDidStart''':: |
291 | 62 | Luci Stanescu | This notification is sent when all the components have been initialized. Note: it doesn't mean that all components have succeeded, for example, the account might not have registered by this time, but the registration process will have started. |
292 | 62 | Luci Stanescu | [[BR]]timestamp:[[BR]] |
293 | 62 | Luci Stanescu | A {{{datetime.datetime}}} object indicating when the notification was sent. |
294 | 62 | Luci Stanescu | '''SIPApplicationWillEnd''':: |
295 | 62 | Luci Stanescu | This notification is sent as soon as the {{{stop()}}} method has been called. |

All components have been given reasonable time to shutdown gracefully, such as the account unregistering. However, because of factors outside the control of the middleware, such as network problems, some components might not have actually shutdown gracefully; this is needed because otherwise the SIPApplication could hang indefinitely (for example because the system is no longer connected to a network and it cannot be determined when it will be again). |

310 | 63 | Luci Stanescu | == SIP Sessions == |
311 | 1 | Adrian Georgescu | |
312 | 63 | Luci Stanescu | SIP sessions are supported by the {{{sipsimple.session.Session}}} class and independent stream classes, which need to implement the {{{sipsimple.streams.IMediaStream}}} interface. The {{{Session}}} class takes care of the signalling, while the streams offer the actual media support which is negotiated by the {{{Session}}}. The streams which are implemented in the SIP SIMPLE middleware are provided in modules within the {{{sipsimple.streams}}} package, but they are accessible for import directly from {{{sipsimple.streams}}}. Currently, the middleware implements two types of streams, one for RTP data, with a concrete implementation in the {{{AudioStream}}} class, and one for MSRP sessions, with concrete implementations in the {{{ChatStream}}}, {{{FileTransferStream}}} and {{{DesktopSharingStream}}} classes. However, the application can provide its own stream implementation, provided they respect the {{{IMediaStream}}} interface. |
313 | 63 | Luci Stanescu | |
314 | 74 | Luci Stanescu | The {{{sipsimple.streams}}} module also provides a mechanism for automatically registering media streams in order for them to be used for incoming sessions. This is explained in more detail in [wiki:SipMiddlewareApi#MediaStreamRegistry MediaStreamRegistry]. |
315 | 65 | Luci Stanescu | |
316 | 44 | Adrian Georgescu | === Session === |
317 | 1 | Adrian Georgescu | |
318 | 1 | Adrian Georgescu | Implemented in [browser:sipsimple/session.py] |
319 | 26 | Luci Stanescu | |
320 | 1 | Adrian Georgescu | A {{{sipsimple.session.Session}}} object represents a complete SIP session between the local and a remote endpoints. Both incoming and outgoing sessions are represented by this class. |
321 | 1 | Adrian Georgescu | |
322 | 1 | Adrian Georgescu | A {{{Session}}} instance is a stateful object, meaning that it has a {{{state}}} attribute and that the lifetime of the session traverses different states, from session creation to termination. |
323 | 2 | Adrian Georgescu | State changes are triggered by methods called on the object by the application or by received network events. |
324 | 1 | Adrian Georgescu | These states and their transitions are represented in the following diagram: |
325 | 63 | Luci Stanescu | |
326 | 1 | Adrian Georgescu | Although these states are crucial to the correct operation of the {{{Session}}} object, an application using this object does not need to keep track of these states, as a set of notifications is also emitted, which provide all the necessary information to the application. |
327 | 63 | Luci Stanescu | |
328 | 63 | Luci Stanescu | The {{{Session}}} is completely independent of the streams it contains, which need to be implementations of the {{{sipsimple.streams.IMediaStream}}} interface. This interface provides the API by which the {{{Session}}} communicates with the streams. This API should not be used by the application, unless it also provides stream implementations or a SIP INVITE session implementation. |

330 | 63 | Luci Stanescu | ==== methods ==== |
331 | 63 | Luci Stanescu | |
332 | 63 | Luci Stanescu | '''!__init!__'''(''self'', '''account'''):: |

338 | 63 | Luci Stanescu | Before contacting the remote party, a {{{SIPSessionNewOutgoing}}} notification will be emitted. |
339 | 63 | Luci Stanescu | If there is a failure or the remote party rejected the offer, a {{{SIPSessionDidFail}}} notification will be sent. |
340 | 63 | Luci Stanescu | Any time a ringing indication is received from the remote party, a {{{SIPSessionGotRingIndication}}} notification is sent. |
341 | 63 | Luci Stanescu | If the remote party accepted the session, a {{{SIPSessionWillStart}}} notification will be sent, followed by a {{{SIPSessionDidStart}}} notification when the session is actually established. |
342 | 63 | Luci Stanescu | This method may only be called while in the {{{None}}} state. |

360 | 63 | Luci Stanescu | Reject an incoming session and move it to the {{{terminaing}}} state, which eventually leads to the {{{terminated}}} state. |
361 | 63 | Luci Stanescu | Calling this method will cause the {{{Session}}} object to emit a {{{SIPSessionDidFail}}} notification once the session has been rejected. |
362 | 63 | Luci Stanescu | This method may only be called while in the {{{incoming}}} state. |
363 | 63 | Luci Stanescu | [[BR]]''code'':[[BR]] |

367 | 63 | Luci Stanescu | '''accept_proposal'''(''self'', '''streams'''):: |
368 | 63 | Luci Stanescu | When the remote party proposes to add some new streams, signaled by the {{{SIPSessionGotProposal}}} notification, the application can use this method to accept the stream(s) being proposed. |
369 | 63 | Luci Stanescu | After calling this method a {{{SIPSessionGotAcceptProposal}}} notification is sent, unless an error occurs while setting up the new stream, in which case a {{{SIPSessionHadProposalFailure}}} notification is sent and a rejection is sent to the remote party. As with any action which causes the streams in the session to change, a {{{SIPSessionDidRenegotiateStreams}}} notification is also sent. |

385 | 63 | Luci Stanescu | '''remove_stream'''(''self'', '''stream'''):: |
386 | 63 | Luci Stanescu | Stop the stream and remove it from the session, informing the remote party of this. Although technically this is also done via an SDP negotiation which may fail, the stream will always get remove (if the remote party refuses the re-INVITE, the result will be that the remote party will have a different view of the active streams than the local party). |
387 | 63 | Luci Stanescu | This method may only be called while in the {{{connected}}} state. |
388 | 63 | Luci Stanescu | '''cancel_proposal'''(''self''):: |
389 | 63 | Luci Stanescu | This method cancels a proposal of adding a stream to the session by sending a CANCEL request. A {{{SIPSessionGotRejectProposal}}} notification will be sent with code 487. |

572 | 50 | Adrian Georgescu | |
573 | 39 | Luci Stanescu | The {{{sipsimple.session.SessionManager}}} class is a singleton, which acts as the central aggregation point for sessions within the middleware. |
574 | 39 | Luci Stanescu | Although it is mainly used internally, the application can use it to query information about all active sessions. |
575 | 64 | Luci Stanescu | The SessionManager is implemented as a singleton, meaning that only one instance of this class exists within the middleware. The SessionManager is started by the SIPApplication and takes care of handling incoming sessions. |

593 | 1 | Adrian Georgescu | |
594 | 66 | Luci Stanescu | This interface describes the API which the {{{Session}}} uses to communicate with the streams. All streams used by the {{{Session}}} __must__ respect this interface. |
595 | 1 | Adrian Georgescu | |
596 | 1 | Adrian Georgescu | ==== methods ==== |
597 | 65 | Luci Stanescu | |
598 | 1 | Adrian Georgescu | '''!__init!__'''(''self'', ''account''):: |
599 | 65 | Luci Stanescu | Initializes the generic stream instance. |
600 | 65 | Luci Stanescu | '''new_from_sdp'''(''cls'', ''account'', ''remote_sdp'', ''stream_index''):: |
601 | 65 | Luci Stanescu | A classmethod which returns an instance of this stream implementation if the sdp is accepted by the stream or None otherwise. |
602 | 65 | Luci Stanescu | [[BR]]account:[[BR]] |
603 | 65 | Luci Stanescu | The {{{sipsimple.account.Account}}} or {{{sipsimple.account.BonjourAccount}}} object the session which this stream would be part of is associated with. |
604 | 65 | Luci Stanescu | [[BR]]remote_sdp:[[BR]] |
605 | 65 | Luci Stanescu | The {{{FrozenSDPSession}}} which was received by the remote offer. |
606 | 1 | Adrian Georgescu | [[BR]]stream_index:[[BR]] |
607 | 65 | Luci Stanescu | An integer representing the index within the list of media streams within the whole SDP which this stream would be instantiated for. |
608 | 65 | Luci Stanescu | '''get_local_media'''(''self'', ''for_offer''):: |
609 | 65 | Luci Stanescu | Return an {{{SDPMediaStream}}} which represents an offer for using this stream if {{{for_offer}}} is {{{True}}} and a response to an SDP proposal otherwise. |
610 | 1 | Adrian Georgescu | [[BR]]for_offer:[[BR]] |
611 | 65 | Luci Stanescu | {{{True}}} if the {{{SDPMediaStream}}} will be used for an SDP proposal and {{{False}}} if for a response. |
612 | 65 | Luci Stanescu | '''initialize'''(''self'', ''session'', ''direction''):: |
613 | 65 | Luci Stanescu | Initializes the stream. This method will get called as soon as the stream is known to be at least offered as part of the {{{Session}}}. If initialization goes fine, the stream must send a {{{MediaStreamDidInitialize}}} notification or a {{{MediaStreamDidFail}}} notification otherwise. |
614 | 65 | Luci Stanescu | [[BR]]session:[[BR]] |
615 | 65 | Luci Stanescu | The {{{Session}}} object this stream will be part of. |
616 | 1 | Adrian Georgescu | [[BR]]direction:[[BR]] |
617 | 65 | Luci Stanescu | {{{"incoming"}}} if the stream was created because of a received proposal and {{{"outgoing"}}} if a proposal was sent. Note that this need not be the same as the initial direction of the {{{Session}}} since streams can be proposed in either way using re-INVITEs. |
618 | 65 | Luci Stanescu | '''start'''(''self'', ''local_sdp'', ''remote_sdp'', ''stream_index''):: |
619 | 65 | Luci Stanescu | Starts the stream. This method will be called as soon is known to be used in the {{{Session}}} (eg. only called for an incoming proposal if the local party accepts the proposed stream). If starting succeeds, the stream must send a {{{MediaStreamDidStart}}} notification or a {{{MediaStreamDidFail}}} notification otherwise. |
620 | 65 | Luci Stanescu | [[BR]]local_sdp:[[BR]] |
621 | 65 | Luci Stanescu | The {{{FrozenSDPSession}}} which is used by the local endpoint. |
622 | 65 | Luci Stanescu | [[BR]]remote_sdp:[[BR]] |
623 | 65 | Luci Stanescu | The {{{FrozenSDPSession}}} which is used by the remote endpoint. |
624 | 1 | Adrian Georgescu | [[BR]]stream_index:[[BR]] |
625 | 65 | Luci Stanescu | An integer representing the index within the list of media streams within the whole SDP which this stream is represented by. |
626 | 65 | Luci Stanescu | '''validate_update'''(''self'', ''remote_sdp'', ''stream_index''):: |
627 | 65 | Luci Stanescu | This method will be called when a re-INVITE is received which changes the parameters of the stream within the SDP. The stream must return {{{True}}} if the changes are acceptable or {{{False}}} otherwise. If any changed streams return {{{False}}} for a re-INVITE, the re-INVITE will be refused with a negative response. This means that streams must not changed any internal data when this method is called as the update is not guaranteed to be applied even if the stream returns {{{True}}}. |
628 | 65 | Luci Stanescu | [[BR]]remote_sdp:[[BR]] |
629 | 65 | Luci Stanescu | The {{{FrozenSDPSession}}} which is used by the remote endpoint. |
630 | 1 | Adrian Georgescu | [[BR]]stream_index:[[BR]] |
631 | 65 | Luci Stanescu | An integer representing the index within the list of media streams within the whole SDP which this stream is represented by. |
632 | 65 | Luci Stanescu | '''update'''(''self'', ''local_sdp'', ''remote_sdp'', ''stream_index''):: |
633 | 65 | Luci Stanescu | This method is called when the an SDP negotiation initiated by either the local party or the remote party succeeds. The stream must update its internal state according to the new SDP in use. |
634 | 65 | Luci Stanescu | [[BR]]local_sdp:[[BR]] |
635 | 65 | Luci Stanescu | The {{{FrozenSDPSession}}} which is used by the local endpoint. |
636 | 65 | Luci Stanescu | [[BR]]remote_sdp:[[BR]] |
637 | 65 | Luci Stanescu | The {{{FrozenSDPSession}}} which is used by the remote endpoint. |
638 | 55 | Adrian Georgescu | [[BR]]stream_index:[[BR]] |
639 | 65 | Luci Stanescu | An integer representing the index within the list of media streams within the whole SDP which this stream is represented by. |
640 | 55 | Adrian Georgescu | '''hold'''(''self''):: |
641 | 65 | Luci Stanescu | Puts the stream on hold if supported by the stream. Typically used by audio and video streams. The stream must immediately stop sending/receiving data and calls to {{{get_local_media()}}} following calls to this method must return an SDP which reflects the new hold state. |
642 | 65 | Luci Stanescu | '''unhold'''(''self''):: |
643 | 65 | Luci Stanescu | Takes the stream off hold. Typically used by audio and video streams. Calls to {{{get_local_media()}}} following calls to this method must return an SDP which reflects the new hold state. |
644 | 65 | Luci Stanescu | '''deactivate'''(''self''):: |
645 | 65 | Luci Stanescu | This method is called on a stream just before the stream will be removed from the {{{Session}}} (either as a result of a re-INVITE or a BYE). This method is needed because it avoids a race condition with streams using stateful protocols such as TCP: the stream connection might be terminated before the SIP signalling announces this due to network routing inconsistencies and the other endpoint would not be able to distinguish between this case and an error which caused the stream transport to fail. The stream must not take any action, but must consider that the transport being closed by the other endpoint after this method was called as a normal situation rather than an error condition. |
646 | 55 | Adrian Georgescu | '''end'''(''self''):: |
647 | 65 | Luci Stanescu | Ends the stream. This must close the underlying transport connection. The stream must send a {{{MediaStreamWillEnd}}} just after this method is called and a {{{MediaStreamDidEnd}}} as soon as the operation is complete. This method is always be called by the {{{Session}}} on the stream if at least the {{{initialize()}}} method has been called. This means that once a stream sends the {{{MediaStreamDidFail}}} notification, the {{{Session}}} will still call this method. |
648 | 55 | Adrian Georgescu | |
649 | 65 | Luci Stanescu | ==== atributes ==== |
650 | 65 | Luci Stanescu | |
651 | 65 | Luci Stanescu | '''type''' (class attribute):: |
652 | 65 | Luci Stanescu | A string identifying the stream type (eg: {{{"audio"}}}, {{{"video"}}}). |
653 | 65 | Luci Stanescu | '''priority''' (class attribute):: |
654 | 65 | Luci Stanescu | An integer value indicating the stream priority relative to the other streams types (higher numbers have higher priority). |
655 | 65 | Luci Stanescu | '''hold_supported''':: |
656 | 65 | Luci Stanescu | True if the stream supports hold |
657 | 65 | Luci Stanescu | '''on_hold_by_local''':: |

661 | 55 | Adrian Georgescu | '''on_hold''':: |
662 | 65 | Luci Stanescu | True if either on_hold_by_local or on_hold_by_remote is true |
663 | 65 | Luci Stanescu | |
664 | 65 | Luci Stanescu | ==== notifications ==== |
665 | 65 | Luci Stanescu | |
666 | 55 | Adrian Georgescu | These notifications must be generated by all streams in order for the {{{Session}}} to know the state of the stream. |
667 | 65 | Luci Stanescu | |
668 | 55 | Adrian Georgescu | '''MediaStreamDidInitialize''':: |
669 | 65 | Luci Stanescu | Sent when the stream has been successfully initialized. |
670 | 55 | Adrian Georgescu | '''MediaStreamDidStart''':: |
671 | 65 | Luci Stanescu | Sent when the stream has been successfully started. |
672 | 55 | Adrian Georgescu | '''MediaStreamDidFail''':: |
673 | 65 | Luci Stanescu | Sent when the stream has failed either as a result of calling one of its methods, or during the normal operation of the stream (such as the transport connection being closed). |
674 | 55 | Adrian Georgescu | '''MediaStreamWillEnd''':: |
675 | 65 | Luci Stanescu | Sent immediately after the {{{end()}}} method is called. |
676 | 55 | Adrian Georgescu | '''MediaStreamDidEnd''':: |
677 | 66 | Luci Stanescu | Sent when the {{{end()}}} method finished closing the stream. |
678 | 55 | Adrian Georgescu | |
679 | 66 | Luci Stanescu | === MediaStreamRegistry === |
680 | 1 | Adrian Georgescu | |
681 | 66 | Luci Stanescu | The MediaStream registry is a collection of classes which implement {{{IMediaStream}}}. This collection is used by the {{{Session}}} to select a stream class for instantiation in the case of an incomming session. The streams are included in the collection in the descending order of their priority. Thus, streams with a higher priority will be tried first by the {{{Session}}}. This object is a Singleton so references to the same object can be obtained by a simple instantiation. |
682 | 66 | Luci Stanescu | |
683 | 1 | Adrian Georgescu | There are several pre-built streams based on the {{{IMediaStream}}} API: |
684 | 1 | Adrian Georgescu | * {{{sipsimple.streams.rtp.AudioStream}}} - Audio stream based on RTP |
685 | 66 | Luci Stanescu | * {{{sipsimple.streams.msrp.ChatStream}}} - Chat stream based on MSRP |
686 | 1 | Adrian Georgescu | * {{{sipsimple.streams.msrp.FileTransferStream}}} - File Transfer stream based on MSRP |
687 | 66 | Luci Stanescu | * {{{sipsimple.streams.msrp.DesktopSharingStream}}} - Desktop Sharing stream based on VNC over MSRP |
688 | 66 | Luci Stanescu | |
689 | 66 | Luci Stanescu | Other streams which are created by the application must be registered in this registry. For a simple way of doing this, see [wiki:SipMiddlewareApi#MediaStreamRegistrar MediaStreamRegistrar]. |

694 | 66 | Luci Stanescu | Instantiate the MediaStreamRegistry. This will be called just once when first (and only) instance is created. |
695 | 66 | Luci Stanescu | '''!__iter!__'''(''self''):: |
696 | 66 | Luci Stanescu | This method allows the registry to be iterated through and will return classes which were registered to it. |
697 | 66 | Luci Stanescu | '''add'''(''self'', '''cls'''):: |
698 | 66 | Luci Stanescu | Add {{{cls}}} to the registry of streams. The class must implement the {{{IMediaStream}}} interface. |

862 | 1 | Adrian Georgescu | |
863 | 68 | Luci Stanescu | The {{{MSRPStreamBase}}} is used as a base class for streams using the MSRP protocol. Within the SIP SIMPLE middleware, this hold for the {{{ChatStream}}}, {{{FileTransferStream}}} and {{{DesktopSharingStream}}} classes, however the application can also make use of this class to implement some other streams based on the MSRP protocol as a transport. |
864 | 68 | Luci Stanescu | |
865 | 68 | Luci Stanescu | ==== methods ==== |
866 | 68 | Luci Stanescu | |
867 | 69 | Luci Stanescu | Of the methods defined by the {{{IMediaStream}}} interface, only the {{{new_from_sdp}}} method is not implemented in this base class and needs to be provided by the subclasses. Also, the subclasses can defined methods of the form {{{_handle_XXX}}}, where XXX is a MSRP method name in order to handle incoming MSRP requests. Also, since this class registers as an observer for itself, it will receive the notifications it sends so subclasses can define methods having the signature {{{_NH_<notification name>(self, notification)}}} as used throughout the middleware in order to do various things at the different points within the life-cycle of the stream. |

1248 | 64 | Luci Stanescu | |
1249 | 64 | Luci Stanescu | There is no standard defining this usage but is fairly easy to implement in clients that already support MSRP.

1265 | 1 | Adrian Georgescu | [[BR]]handler:[[BR]] |
1266 | 71 | Luci Stanescu | An object implementing the {{{IDesktopSharingHandler}}} interface which will act as the handler for RFB data. |

1271 | 71 | Luci Stanescu | This is a writable property which can be used to get or set the object implementing {{{IDesktopSharingHandler}}} which acts as the handler for RFB data. For incoming {{{DesktopSharingStreams}}}, this must be set by the application before the stream starts. |
1272 | 71 | Luci Stanescu | '''incoming_queue''':: |
1273 | 71 | Luci Stanescu | A {{{eventlet.coros.queue}}} instance on which incoming RFB data is written. The handler should wait for data on this queue. |
1274 | 71 | Luci Stanescu | '''outgoing_queue''':: |
1275 | 64 | Luci Stanescu | A {{{eventlet.coros.queue}}} instance on which outgoing RFB data is written. The handler should write data on this queue. |
1276 | 72 | Luci Stanescu | |
1277 | 64 | Luci Stanescu | |
1278 | 72 | Luci Stanescu | == Account management == |
1279 | 1 | Adrian Georgescu | |
1280 | 72 | Luci Stanescu | Account Management is implemented in [browser:sipsimple/account.py] ({{{sipsimple.account}}} module) and offers support for SIP accounts registered at SIP providers and SIP bonjour accounts which are discovered using mDNS. |
1281 | 64 | Luci Stanescu | |
1282 | 72 | Luci Stanescu | === Account === |
1283 | 72 | Luci Stanescu | |
1284 | 64 | Luci Stanescu | The {{{sipsimple.account.Account}}} objects represent the SIP accounts which are registered at SIP providers. It has a dual purpose: it acts as both a container for account-related settings and as a complex object which can be used to interact with various per-account functions, such as presence, registration etc. This page documents the latter case, while the former is explained in the [wiki:SipConfigurationAPI#Account Configuration API]. |
1285 | 64 | Luci Stanescu | |
1286 | 72 | Luci Stanescu | There is exactly one instance of {{{Account}}} per SIP account used and it is uniquely identifiable by its SIP ID, in the form ''user@domain''. It is a singleton, in the sense that instantiating {{{Account}}} using an already used SIP ID will return the same object. However, this is not the recommended way of accessing accounts, as this can lead to creation of new ones; the recommended way is by using the [wiki:SipMiddlewareApi#AccountManager AccountManager]. The next sections will use a lowercase, monospaced {{{account}}} to represent an instance of {{{Account}}}. |
1287 | 64 | Luci Stanescu | |
1288 | 64 | Luci Stanescu | ==== states ==== |
1289 | 64 | Luci Stanescu | |
1290 | 64 | Luci Stanescu | The {{{Account}}} objects have a setting flag called {{{enabled}}} which, if set to {{{False}}} will deactivate it: none of the internal functions will work in this case; in addition, the application using the middleware should not do anything with a disabled account. After changing it's value, the {{{save()}}} method needs to be called, as the flag is a setting and will not be used until this method is called: |
1291 | 64 | Luci Stanescu | {{{ |
1292 | 64 | Luci Stanescu | account.enabled = True |
1293 | 64 | Luci Stanescu | account.save() |
1294 | 64 | Luci Stanescu | }}} |
1295 | 64 | Luci Stanescu | |
1296 | 64 | Luci Stanescu | The {{{Account}}} objects will activate automatically when they are loaded/created if the {{{enabled}}} flag is set to {{{True}}} and the {{{sipsimple.engine.Engine}}} is running; if it is not running, the accounts will activate after the engine starts. |
1297 | 64 | Luci Stanescu | |
1298 | 64 | Luci Stanescu | In order to create a new account, just create a new instance of {{{Account}}} with an id which doesn't belong to any other account. |
1299 | 64 | Luci Stanescu | |
1300 | 64 | Luci Stanescu | The other functions of {{{Account}}} which run automatically have other enabled flags as well. They will only be activated when both the global enabled flag is set and the function-specific one. These are: |
1301 | 64 | Luci Stanescu | |
1302 | 64 | Luci Stanescu | '''Account.registration.enabled''':: |
1303 | 64 | Luci Stanescu | This flag controls the automatic registration of the account. The notifications '''SIPAccountRegistrationDidSucceed''', '''SIPAccountRegistrationDidFail''' and '''SIPAccountRegistrationDidEnd''' are used to inform the status of this registration. |
1304 | 64 | Luci Stanescu | '''Account.presence.enabled''':: |
1305 | 64 | Luci Stanescu | This flag controls the automatic subscription to buddies for the ''presence'' event and the publication of data in this event. (Not implemented yet) |
1306 | 1 | Adrian Georgescu | '''Account.dialog_event.enabled''':: |
1307 | 64 | Luci Stanescu | This flag controls the automatic subscription to buddies for the ''dialog-info'' event and the publication of data in this event. (Not implemented yet) |
1308 | 64 | Luci Stanescu | '''Account.message_summary.enabled''':: |
1309 | 64 | Luci Stanescu | This flag controls the automatic subscription to the ''message-summary'' event in order to find out about voicemail messages. (Not implemented yet) |
1310 | 64 | Luci Stanescu | |
1311 | 72 | Luci Stanescu | The {{{save()}}} method needs to be called after changing these flags in order for them to take effect. The methods available on {{{Account}}} objects are inherited from [wiki:SipConfigurationAPI#SettingsObject SettingsObject]. |
