Hi tele, the problem is with the re-INVITE which is malformed. original INVITE had the FROM URI <sip:396006660084@plx-c5-pbx.plexia.com:5060>, but the re-INVITE has <sip:0104491093@plx-c5-pbx.plexia.com:5060>.... the FROM URI does not change during the dialog. It looks like UA bug. regards, bogdan tele wrote:

Hi, The vendor said: "Our implementation of SIP manages in various way regarding the other device in test, header field “Record” (in particular not retrasmit all param but filter, for example the "lr" parameter). That cause calling to consider the proxy of type “strict” and changes the Request-Uri of the ACK" We've also notice that the vendor UA not mirror all the RR parameters for example: RR of INVITE from OpenSER to -> UA Record-Route: <sip:IP;lr=on;ftag=80b12060-52d7a475-13c4-53c-e3a1aea-53c;vsf=AAAAAAMIBgQEDwcGCAR4DHJeXkkYTQQbQ0xJHkBsZXhpYS5jb206NTA2MA--> and the Re-INVITE from UA to OpenSER Route: <sip:IP;vsf=AAAAAAMIBgQEDwcGCAR4DHJeXkkYTQQbQ0xJHkBsZXhpYS5jb206NTA2MA--> So i think OpenSER use the ftag and vsf parameter of Route header for generate the correct From header.. is that true? so the vendor UA MUST mirror untouched all the parameters? thanks, :tele On Tue, 2007-04-03 at 17:27 +0300, Bogdan-Andrei Iancu wrote: _______________________________________________ Users mailing list Users(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/users

Hi bogdan, I'm apologize to insist regarding this but i'm trying to understand. i think that i've not supplied to you all the necessary informations. If you have a look on the pcap attached, there are two call, the first was OK and the second one with the FROM problem. I can see the Re-INVITE FROM URI and TO URI are correctly swapped, the only difference in the UA with problem is the Route header that was mirror with only the vsf parameter and not the other ones. If i'm wrong could you please explain much more the issue, still unclear to me :-) thank you very much, :tele On Mon, 2007-04-16 at 17:16 +0300, Bogdan-Andrei Iancu wrote: > Hi tele, > > yes, the RR headers must be mirror without no change (URI and > parameters), but the problem in your case was not the RR (which was ok), > but the FROM URI - the re-INVITE has a different FROM URI than the > original INVITE. > > regards, > bogdan > > tele wrote: > >> Hi, >> >> The vendor said: >> >> "Our implementation of SIP manages in various way regarding the other >> device in test, header field “Record” (in particular not retrasmit all >> param but filter, for example the "lr" parameter).
