= Using SIP = === PSTN Outbound === Price list for dialing to PSTN destinations is available [https://mdns.sipthor.net/sip_rates.html here]. The call costs are logged in the Credit section of your [http://x.sip2sip.info SIP settings page]. To make calls to PSTN destinations you must have a positive credit. To add credit to your SIP account at http://x.sip2sip.info?tab=credit To dial a PSTN destination dial + or 00 in front of the actual number including country code. The number must be a fully qualified E.164 number (country code + network number + subscriber number). First an ENUM lookup is attempted. If a SIP destination is found, the call will be routed to it, if ENUM lookup does not return a valid SIP address, the call is directed to a PSTN gateway. To set your caller id please open a ticket in the support interface. '''Important notes''' * Service numbers for premium services may not be reachable * Emergency access number (e.g. 911, 112) are not available * Not all international PSTN prefixes may be available depending on the capabilities of our outbound carriers === PSTN Inbound === As you own a publicly reachable SIP address, you may receive calls from any SIP device that knows your address including a PSTN gateway. You can receive calls from PSTN if you own a telephone number (not provided by SIP2SIP) and if the SIP gateway provider that handles that number can translate that number into your SIP address. Technically, if you number is in ENUM e164.arpa or e164.org trees you can simply map your ENUM number to your SIP address yourself. Any ENUM ready gateway will be able to automatically find the SIP address you configured for your ENUM number. == NAT Traversal == [[TOC(WikiStart, Sip*, depth=3)]] Practically you do not need to set anything special in the client, NAT traversal is solved automatically by the SIP2SIP server infrastructure. We recommend actually that you check to have disabled all client features related to NAT traversal: 1. Disable any keep-alive technique like PING, NOTIFY, OPTION, CR/LF or STUN 1. Disable any SIP ALG support in the border router, most of the so called 'SIP enabled' routers on the market today are [http://www.voip-info.org/wiki/view/Routers+SIP+ALG simply broken] 1. Disable voice activation detection (VAD) in your device Beware that corporate firewalls that have an explicit policy against SIP or poorly implemented [http://www.voip-info.org/wiki/view/Routers+SIP+ALG SIP ALGs] may still block your SIP signaling and/or media traffic. You need un-restricted access to the following ports used by SIP2SIP infrastructure: || '''Port range''' || '''Protocol''' || '''Description''' || '''Application''' || || 5060 || UDP || SIP signaling || OpenSIPS - SIP Proxy/Registrar/Presence Agent || || 50000:60000 || UDP || RTP media || !MediaProxy - RTP media relay || || 2855 || TLS || MSRP media || MSRP relay - MSRP media relay || || 443 || TLS || XCAP storage || OpenXCAP - Presence policy management || == SIP Address == When you register a SIP account on SIP2SIP, a SIP address under @sip2sip.info domain is automatically allocated to you. You must provide this SIP address to those that want to reach you. SIP protocol uses the same identifier format as an email address in the form of user@domain. Actually, you can use the same address for both email messaging and SIP applications providing that you have control upon your own domain, its DNS records and access to a service like SIP2SIP. To create SIP addresses under your own domains, you can register or transfer for a fee your Internet domains at https://secure.dns-hosting.info. On the same platform you can provision your DNS zones and records required for SIP services and create your own SIP accounts. The number of SIP addresses you may create is limited by a fair use policy dependent on the general use of the platform. First [wiki:SipDeviceConfiguration configure your SIP device]. == Internet Sessions == * To test audio sessions, call 3333, you should hear some music playing * To test microphone call 4444, you should hear your echo back * You may call to any other SIP account user@domain === Voicemail === * To access your voicemail or mailbox settings dial 1233 * Your voice messages are delivered to your e-mail address === IM and File Transfer === * For instant messaging your client must support MSRP protocol and its MSRP relay extension === Conferencing === * To test the conference server send an INVITE with any of the supported media to sip:test@conference.sip2sip.info You may replace test with any username you wish, a conference room will be created on the fly. To obtain the conference information send a SUBSCRIBE request multi-party conferencing for Event conference RFC 4575. The NOTIFY contains detailed information with the list of participants, their connected endpoints, media type audio, IM and stream status. To add or remove participants, SylkServer support INVITE and REFER methods as defined in RFC4579. file transfer see http://sylkserver.com/applications.phtml See http://sylkserver.com/applications.phtml for more information about conferencing capabilities. === Session Details === * To review your SIP sessions go to https://mdns.sipthor.net/CDRTool [[Image(sip2sip-sessions-search.png,link=http://cdrtool.ag-projects.com)]] == Presence == SIP2SIP provides a SIP presence agent that handles SUBSCRIBE and PUBLISH methods for presence events. 1. To publish your presence send PUBLISH for '''Event: presence''' to your own SIP address, containing the body describing your presence information in PIDF format 1. To subscribe to a SIP address, send a SUBSCRIBE message for '''Event: presence''' 1. To subscribe to a list of SIP addresses (a.k.a. rls-services), send a SUBSCRIBE message for '''Event: presence''' containing an extra header: '''Require: eventlist''' 1. To monitor who has subscribed to your presence information you must send SUBSCRIBe for '''Event: presence.winfo''' to your own SIP address 1. To allow others to subscribe to your published information you must use XCAP protocol for manipulating '''pres-rules''' policy document 1. To store your buddy list on the server you must use XCAP protocol for manipulating '''resource-lists''' and '''rls-services''' documents [[Image(http://openxcap.org/raw-attachment/wiki/WikiStart/SIMPLE-Server.png,link=http://openxcap.org)]]
