How to setup Ozeki VoIP SIP SDK with VoIPtalk

For making VoIP calls first you need to sign up to the service of a service provider (or connect to a PBX). In this guide you will learn how to connect to VoIPtalk when you use Ozeki VoIP SIP SDK. After following this tutorial you will be able to make VoIP calls via VoIPtalk with the Ozeki SIP SDK effectively.

This setup guide explains in detail how you can use a SIP account provided by an Internet based VoIP telephone provider (namely VoIPtalk).

VoIP telephone service providers offer a telephone service over the Internet. They can forward calls to traditional telephone networks and to Internet users signed up to their network. When you sign up for the service, you will receive a SIP account (an IP address, a username and a password, plus some other details). To make voice calls from Ozeki VoIP SIP SDK, you need to configure the SIP account details.

After signing up for the service of VoIPtalk and following the configuration steps of this guide you will have a system that works in the way as Figure 1 demonstrates:

With the help of Ozeki VoIP SIP SDK you will be able to initiate VoIP calls from your application via the SIP account of VoIPtalk. Then calls can be forwarded toward mobile phones or any landline phones.
