I do VoIP calls using two systems. With my softphone dialler I can establish computer to computer tunnelling, thus setting up a network with computer endusers. Now, I also use a PAP2 interfaced with my computer network card to do VoIP calls. Some of my end users can use my dialler but they cannot ues my PAP2 to make VoIP calls because the ports are blocked. My question is, how can I make my two systems talk to each other, so that tunnelling can be established on my PAP2 system?
