Assuming you send the OPTIONS with pjsua_call_send_request(), the transaction status will be reported in on_call_tsx_state() callback. Alternatively, maybe you can also use the RTP statistic to see if RTP is still active. See pjsua_call_dump() implementation in pjsua_call.c on how to retrieve media statistic of the call. You'll need to include pjsua_internal.h though, which is something that I don't normally recommend. cheers, -benny > thanks for all the help and nice job being done in the API, > > Thiago
