This guide explains how you can connect Ozeki VoIP SIP SDK to your PBXnSIP server. All you need to do is to create an extension in PBXnSIP and Ozeki VoIP SIP SDK can use this extension to register to the PBX.

Voice Over IP is one of today's fastest growing technology. It makes it possible to create an advanced telephone application based on the existing network. VoIP technology is based on converting the voice into packets and transmits these packets towards the destination.

This page explains you how to connect Ozeki VoIP SIP SDK to your PBXnSIP server.
