Hi Raviprakash
Thanks.
i use rtpproxy the same openser server
"rtpproxyt -l 192.168.100.5 -s udp:*:22222 "
if i do not use any media proxy and just enable ICE feature on both UAC
it still hear voice but after 30 sec CALLEE HANGUP
for complete INVITE message ACK from CALLER UAC is send DIRECT to CALLEE
UAC it necessary to use or pass openser or not ?
Best
