14 CUSAX: Combined Use of SIP and XMPP draft-ivov-xmpp-cusax Emil Ivov - Jitsi Peter Saint-Andre - Cisco Enrico Marocco - Telecom Italia

15 CUSAX: Why? Existing SIP server implementations often have: Rich sets of telephony features (voic , call queues, call parking, 3PCC ) Support for media services (transcoding, call mixing, HNT etc.) Abundance of PSTN gateways Relatively poor support for things like presence, instant messaging, server stored contact lists, file transfer, etc. Existing XMPP server implementations often have: Great support for things like presence, instant messaging, server stored contact lists, file transfer, etc. Poor or no support for anything related to telephony Mostly an implementation issue Entirely based on requests from Unified Communication service provider 15/10

16 CUSAX: What? Double stack clients SIP+XMPP clients Connect simultaneously to SIP and XMPP infrastructure Use SIP for VoIP (only!). No XCAP, no MSRP XMPP for IMP and everything else (no Jingle) XMPP Server CUSAX Client SIP Server 16/10

17 CUSAX Approach Not specifying new stuff. Reuse vcard-s SIP (Call-Info) headers 17/10

18 CUSAX: Matching JIDs to AORs Retrieve SIP AORs from vcard-s <vcard xmlns='vcard-temp'> <TEL> <CELL/> <WORK/> <NUMBER> </NUMBER> </TEL> </vcard> <vcard xmlns='vcard-temp'> <TEL> <CELL/>` <WORK/> </TEL> </vcard> 18/10

19 CUSAX: Matching JIDs to AORs Retrieve JIDs from additional SIP (Contact) headers INVITE SIP/2.0 To: Bob From: Alice Contact: Call-Info: ;purpose=impp 19/10

20 CUSAX: Related Work Similar to SIXPAC but: Does not introduce new SIP headers Does not add new stanza Little interaction between both protocols 20/10

21 CUSAX: Other Details SIP and XMPP infrastructure are meant to be provided by a single maintainer. Account provisioning recommended but out of scope Service Login ID: [ ] Service Passwd: [ ] Service Login SIP ID: [ ] SIP Passwd: [ ] SIP Server: [ ] XMPP JID: [ ] XMPP Passwd:[ ] OK! NOT REALLY OK! 21/10
