I have third party Linux Server, SIP/VOIP, when an IP phones registered with server and are assigned with extension number like 501,502 etc, now these phones make communication with each other by dialing their number. What I want to do is, remove the IP phone and use Raspberry module, and it should work as phone, and connecting push button switch on its GPIO port, set the the calling extension number, so now if switch is pressed it should call to that number and voice threw mic and speaker port
ok for more we will talk
