Dear All, I found one issue in "pjsua_call_set_hold( )" API. Please find the scenario below, 1. Place a call to the remote end and once the call is in connected state, I used to hold the call. The call seems to be in hold state without any issue. Then reinvite if necessary. 2. Now disconnect the first call and place another call and once the call is in connected state, I hold the call. But this time I receives the following error and the application gets closed. *pjsua_call.c Invalid call_id 0 in pjsua_call_set_hold() test.cpp Error in Hold call!!!!: INVITE session a ady terminated (PJSIP_ESESSIONTERMINATED) [status=171140] *Is there any known issue? Also let me know the workaround to fix the issue. Note: The above scenario happens in inbound call also.
