Console SIP client?

To work a client with the task to implement a dial out from the server to the subscribers of Beeline (to their rooms) with the ability to reset, adjust the time dial, receive data about the result of the call.
Just doing the dialer, the subscriber picked up the phone - reset it took waiting for a while - reset.
No experience with telephony in General, googling found the solution in the sipp, whether funds sipp to work with the real PBX? or is it only for testing utility?
