Hi Ted, | If I'm using pjsua_call_make_call to make an outgoing call how do | I stop this call if it hasn't answered yet? | I know that I can hangup a call based on the call_id but before the | call is actually answered no call_id is given Did you notice the last parameter of pjsua_call_make_call()? You will get a call_id from that, even if the call is not connected. | so I'm wondering how to terminate it before it even answers. You can perfectly use pjsua_call_hangup() with the call_id given by pjsua_call_make_call(). Or do I miss something? Good luck, Sebastian.
