Hey, I'm gonna test my script to see whether it calls a number ( 435-879-3456 at asteriskserver.com) or (sip:user at astersikserver.com<sip%3Auser at astersikserver.com>) like below: (I've used pjsua_call_make_call as function in the script ) On command prompt(DOS): pjsua(exe) 435-879-3456 at asteriskserver.com or sip:user at asteriskserver.com <sip%3Auser at asteriskserver.com> ->enter Will the above register and call the specified URL or number? If YES, will I able to hear any ringing. I just have my earphone for now. This the first time I'm gonna test, that's why want to know what actually happens. I have already tested the registration thing with "example.com" and it did work. Since it's just test, it says SIP registration failed ( request timeout ) Any help! Thanks!
