Answer 1

Unfortunately there is no step-by-step tutorial for this kind of application. I advise you to complete these four steps:

1. Read iPhone/iPad application guidelines from http://developer.apple.com/
2. Find some VOIP open source projects and inspect them.
3. Read the VOIP standards.
4. Try to transfer VOIP parts from open source projects to your iOS project.

That should be enough to write a VOIP client.
