Re: [Serusers] e2e cancel - ghost calls

Hi all, I'm having a problem related with the "early" CANCEL's. The scenario is the following one : A PSTN call to a SIP phone. When the PSTN decides to cancel the call only a right after initiating, the PSTN will send the CANCEL message to the SER but this is discarded and not forwarded to the correct path to the SIP Phone. So what happens is that we have a ghost call.... The PSTN has already cancelled the call but the SIP phone continues to ring. The code that I have in the SER script is really simple: if(subst_uri('/^sip:(\+[0-9]+)@ 192.168.20.69.*user=phone$/sip:\1@ptinovacao.pt/i')){<http://192.168.20.69.*user=phone$/sip:%5C1@ptinovacao.pt/i'))%7B> record_route(); loose_route(); t_relay_to_udp("192.168.20.5", "5060"); break; } In the log file I see that: RFC3261 transaction matching failed t_lookup_request: no transaction found e2e_cancel: e2e cancel proceeding Could you help me? Thanks in advance. Best Regards, -- Nuno Ribeiro _______________________________________________ Serusers mailing list Serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
