Hi, What is the default duration for the session timer in pjsip library. I have added the two flags PJSIP_INV_SUPPORT_TIMER and PJSIP_INV_REQUIRE_TIMER in both incoming and out going call invites. when i call from one UA built using pjsip to another UA built using pjsip when i close any UA abruptly the session termination takes a long time. Can anyone please help me fix this. Thanks, ravi -------------- next part -------------- An HTML attachment was scrubbed...
