5 | 83 | Adrian Georgescu | SIP SIMPLE client is a Software Development Kit for easy development of Real Time Applications based on SIP and related protocols for Presence, Audio, Instant Messaging (IM), File Transfers and Desktop Sharing. Other media types can be easily added by using an extensible high-level API. |
6 | 49 | Adrian Georgescu | |
7 | 85 | Adrian Georgescu | The software library has undergone several interoperability tests at [http://sipit.net SIPIT] and is of industry strength quality. |

9 | 80 | Adrian Georgescu | == General Features == |
10 | 1 | Adrian Georgescu | |
11 | 26 | Adrian Georgescu | * Written in Python language |
12 | 79 | Adrian Georgescu | * Non-blocking asynchronous design |
13 | 79 | Adrian Georgescu | * Event driven Application Programming Interface |
14 | 54 | Adrian Georgescu | * TLS security for both signaling (SIP) and media planes (MSRP, XCAP) |
15 | 53 | Adrian Georgescu | * Fail-over for DNS lookups, SIP next hop routing and MSRP relay reservation |
16 | 48 | Adrian Georgescu | * Multiple SIP accounts support |
17 | 75 | Adrian Georgescu | * Multiple media types per session (e.g. Audio + Instant Messaging + Desktop Sharing) |
18 | 1 | Adrian Georgescu | * Multiple active session support with add/remove of media within same session |
19 | 75 | Adrian Georgescu | * Compatible with SIMPLE functionality of OpenSIPS and OpenXCAP servers |
20 | 1 | Adrian Georgescu | * Trace capability for all underlying protocols |
21 | 79 | Adrian Georgescu | * Cross platform (Linux, OSX, Windows) |
22 | 75 | Adrian Georgescu | |
23 | 76 | Adrian Georgescu | == Location Discovery == |
24 | 75 | Adrian Georgescu | |
25 | 75 | Adrian Georgescu | * [http://tools.ietf.org/html/rfc3263 RFC3263] next hop resolution lookup |
26 | 1 | Adrian Georgescu | * Bonjour multicast DNS [http://tools.ietf.org/html/draft-lee-sip-dns-sd-uri-03] |
27 | 81 | Adrian Georgescu | * Other lookup mechanisms can be easily added (e.g. P2PSIP or DHT) |
28 | 1 | Adrian Georgescu | |
29 | 76 | Adrian Georgescu | The library uses a separated from the core lookup mechanism for the next hop routing. This important feature allows the library to be used for building SIP clients that operate in combination with any SIP provider (by employing RFC 3263 DNS lookups), in a server-less LAN operation (using Bonjour protocol) or integrated into a network overlay developed by a third party (e.g. P2PSIP overlay). |
