Welcome to the third part of this tutorial series!
In the 1st post, we talked about how to compile pjsip, and run the built in demo on a real device. And in the 2nd post, we discussed setting up your own VoIP server, and actually made our 1st VoIP call from the iPhone to the Mac.
Today, we’re going to show you how to handle basic VoIP operations using pjsip. We’ll go into the details of the mac receiver voip app. Yes, this tutorial is supposed to talk about iOS app. However, since all the APIs provided by pjsip are in C, it’s easier to discuss them in a pure C program.
