Hi Ted, >From sip.log it seems that there are no responses to REGISTER / INVITE messages being sent to your provider. Since you have it working with a softphone perhaps a wireshark trace of the working call compared to the non working call will help. Do you know if the provider requires Registration? What is the domain of your account? Sometimes the domain (sent in To: header etc. ) is separate to the server IP address you actually need to send packets to. If that is the case you can configure the --proxy setting in pjsua.exe sample application. P.S. I hope the username/password specified in your sip.c file are not the real ones. :) Regards, Omar -----Original Message----- From: pjsip [mailto:pjsip-bounces@xxxxxxxxxxxxxxx] On Behalf Of Ted Gerold Sent: Saturday, 16 March 2013 12:19 PM To: PJSip Subject: Problems with Outbound Calls 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. _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip at lists.pjsip.org http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org
