Hi sir, I use simple_pjsua. To register is okay, but to make call is fail. command: "simple_pjsua xxx" But the called party (xxx) has not any incoming call. This making call seems is fail. So how to do it?? Attachment is the log file. Lewis -------------- next part -------------- An HTML attachment was scrubbed...
