Direct VoIP call from one iOS device to another

[Aleksey]

I'am going to develop peer-to-peer VoIP iOS application. And want do it without any SIP proxy, SIP providers and other servers. Just VoIP calls frpm iOSdevice-to-iOSdevice. Both iOSdevice could be somewhere in Internet. Is it real in VoIP (with PJSIP for example and general with SIP)? Could you please point me to main keys that I need for development.

Is it real solve problems with addressing? Anybody know is PJSIP could help with correcting addresing?

Hi

I have implemented two applications by pjsip with connection to server. I'm not sure the pjsip support p2p connection. Maybe you should use other library to making p2p connection. I'm not good enough on this...

Thanks. I'am certainly know that PJSIP support p2p connection. But as i understood there is some problem with addressing.

OK

The problem on p2p connection occur when IP of one of iphones change during the call. If you could notify the new IP to other iPhone, the phones continue to call without problem.

Yes, it's clear. But what if iPhone behind some Proxy and insider some local network. In this situation we should use something like STUN & TURN. SIP Proxy provides such functionality. But I not going to use SIP Servers.
