Hello, I have spent a few days now trying to make an output call with PJSAU but I can not seem to figure out why its not working properly. Here is the program I'm using (I got this example from some pj site): https://www.dropbox.com/s/ltic4hw5hm8p3xz/sip.c Here is my full log file: https://www.dropbox.com/s/61qtwoh25jox8d9/sip.log At first I was getting the 'cant find sound device' which I expected as I'm not trying to connect to an external sound device. I simply want to make a call, play a wav and hangup. So I used: pjsua_set_null_snd_dev() to fix that. Now I can make the call and the other end rings just fine but nothing happens after that. No media state changes, no call_id given. It waits about 5 seconds and disconnects (pjsua is not disconnecting as again there is no media state change). Then PJSUA just tries calling again. So to summarize: o call initiates o i pick up phone and hear nothing o no media state change in pjsua o pjsua calls me 2 more times before quitting. At this point Ive probably spent at least 10 hours on this problem and am desperate. Any help is much appreciated. I tried to provide all possible information. Also I did test my DID provider Vitelity with a soft phone app and it worked great.
