I've asked this question on many other forums and no one seems to know, so that's why I posted in the experts forume. So I just got a new sip phone. It is connected via usb to box A in my bedroom. Box B is in the living room and is running asterisk connected with a Zaptel card to a POTS line. I'm having trouble setting up the phone. Does does box A with the sip phone connected to it need to also be running asterisk? Is there a default asterisk config file for SIP clients? How do I set up box B to be a SIP server to box A? Both box and b sit on the same lan. Any help is appreciated.
