I used this the official version of: http://trac.pjsip.org/repos/browser/pjproject/trunk/pjsip-apps/src/python/samples/call.py And replaced as: # when no sound card found #lib.set_null_snd_dev() print lib.enum_snd_dev() lib.set_snd_dev(5,0) print lib.get_snd_dev() # Create local account #acc = lib.create_account_for_transport(transport, cb=MyAccountCallback()) acc = lib.create_account(pj.AccountConfig("put your asterisk or freeswitch ip", "sip username here", "sip password here")) cb = MyAccountCallback(acc) acc.set_callback(cb) #cb.wait() as you can see its not working still. Then i tried to find some working tools, `python-pjsip` binary after installing the sip-tools for Ubuntu 13.10 i do not find that tool. Is it supposed to be available by default after installing? sun at sun-Alienware-X51:/var/tmp$ python << TAB TAB TAB not showing any python-pjsip python python2 python2.7 python2.7-config python2-config python3 python3.3 python3.3m python3m python-config -------------- next part -------------- An HTML attachment was scrubbed...
