[SR-Users] Handling 422 Message (was: Re: dlg_vars of existing dialog not set after loose_route())

Hi After more intensive testing, I narrowed the issue down. CPE A => Kamailio+dialog => CPE B CPE A is sending an INVITE with a session timer too smal for CPE B. CPE B replies with 422. This causes the dialog module to trigger the 'call failed' event and attempt to delete the dialog data. CPA A does not consider the call failed. It repeats the INVITE with CSEQ + 1 and with the session timer as desired by CPE B. The call is then processed as if in dialog, but some, strangely not all, dialog variables are lost. I fear the repeated invite with identical callID and from_tag causes a race condition in handling the dialog variables. I see there are two attempts by the dialog module to write a CDR with the same callID. After processing the 422 and when the call ends while processing BYE. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
