Hi, I am using pjnath lib, I don't know how to detect connection lost after success session negotiation? pjnath lib doc says "PJ_ICE_STRANS_OP_KEEP_ALIVE" is only used to report TURN Refresh failure. can I get stun keep alive result in a work around method. Thanks in advance. bo -------------- next part -------------- An HTML attachment was scrubbed...
