Hi all, Just a quick update to the issue I reported earlier: I set the SOFIA_DEBUG environment variable to 9 and found that I get the following messages regarding the 487:
tport_wakeup_pri(0x806bbf0): events IN tport_recv_event(0x806bbf0) tport_recv_iovec(0x806bbf0) msg 0x8084fb0 from (udp/10.0.66.27:5060) has 361 bytes, veclen = 1 tport_deliver(0x806bbf0): msg 0x8084fb0 (361 bytes) from udp/10.0.66.9:5060/sip next=(nil) nta: received 487 Request Terminated for INVITE (87778107) nta: 487 Request Terminated was discarded I browsed the source code for the 'discarded' message and found it to be printed in nta.c, line 2699 (from the darcs version). Digging around I saw this comment on line 2657: "/* XXX - should check if msg should be discarded based on via? */". Then I checked the Via headers in both the INVITE sent by Sofia and the 487 received, and verified that they differ: Via from INVITE: Via: SIP/2.0/UDP 10.0.66.27;rport;branch=z9hG4bKrt1vS4B0ZHayF Via from 487: Via: SIP/2.0/UDP 10.0.66.27;rport=5060;received=10.0.66.27;branch=z9hG4bKrt1vS4B0ZHayF As you can see, the softphone adds a 'received' parameter to the Via header. Is this what may be causing the message to be discarded? Thanks again.
