Hi , I had an idea to build my own VOIP app (just as a way to learn something new) for the android and I was wondering if any1 can gimme some ideas on how to get started.. I'm quite new to both VOIP and Android so I am a lil lost on how to go about it..
Go to Sipdroid.com and look at the open-source code for their excellent SIP client. Then reinvent the wheel.
