Dear, Is it possible to send registration message with expires = 0 in between a running call? anyone has this kind of experience using pjsip? Re-Registration message contains expires = 0 where default re-registration time is set to 3600. define PJSUA_REG_INTERVAL 3600 in pjsua.h though this is not happening all time. Sometimes in between a running call this is happening and call is getting dropped. Thanks -------------- next part -------------- An HTML attachment was scrubbed...
