Dear Implementors, I have one phone that wants to REGISTER for TWO addresses of record (sip:2111 & sip:2110).
I think this is done by sending two REGISTRATIONS from the same UAC as follows: REGISTER sip:159.63.70.148 SIP/2.0 From: sip:[EMAIL PROTECTED];tag=29344c29344 To: sip:[EMAIL PROTECTED] Call-Id: c9012720dd1e48e4262f40437eba7b21 Cseq: 1 REGISTER Contact: <sip:[EMAIL PROTECTED];LINEID=09b9dc0322b74342bbdb8b973a7ac8c5> Expires: 3600 Date: Mon, 10 Mar 2003 16:23:53 GMT Accept-Language: en Supported: sip-cc, sip-cc-01, timer, replaces User-Agent: Some-UA Via: SIP/2.0/UDP 159.63.70.218 Content-Length: 0 REGISTER sip:159.63.70.148 SIP/2.0 From: sip:[EMAIL PROTECTED];tag=17834c17834 To: sip:[EMAIL PROTECTED] Call-Id: 0ce49d480dcfc3ca9435a48804548031 Cseq: 1 REGISTER Contact: <sip:[EMAIL PROTECTED];LINEID=ea99e11a59e22dcac96d7f957e9770a3> Expires: 3600 Date: Mon, 10 Mar 2003 16:23:53 GMT Accept-Language: en Supported: sip-cc, sip-cc-01, timer, replaces User-Agent: Some-UA Via: SIP/2.0/UDP 159.63.70.218 Content-Length: 0 However the SIP RFC3261 section 10.2 says that all registrations from the same UAC should use the same Call-ID. I am pretty sure that the spec should instead read as follows: "all registrations from the same UAC should use a different Call-ID for each AOR they are registering, however the call ID for registrations for the same AOR should NOT change." Implementation from Pingtel and SNOM back me up on this, but my stack vendor disagrees. Can anyone help resolve this issue? ________________________________________ Leo Papadopoulos IPC Information Systems, Inc.
