    Hi every body,
    I develop Iphone app, It's make the call by App via wifi / 3g. But i don't know how to do it.
    I use [[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"tel:123456"]] to call but it call via GSM.

    Push notification service can send message,but available for Text because maxsize for payload is 256byte.:rolleyes:

    Please help me!

    You have to include your own VOIP code: the OS will not write your app for you.

    when Iphone A call to Iphone B,
    I will use [[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"tel:{VoIP code of IPhone B}"]], right?

    Two years worth of university level coursework on software engineering, computer networks, communications systems, and signal processing would be a good start.

    This is not as easy as "what code do I use to make a VOIP call".

    Take a look at Siphon
    http://code.google.com/p/siphon/

    It's an open source VOIP project so you can download the source and look through it for educational purposes. You won't be able to use it and distribute on the iTunes store because it is licensed as GPL.

    Question:

    Doesn't Game Kit have APIs for making VOIP really easy?
