[Linphone-developers] Switch between 3G and WiFi on the iPhone during the call

[Shaun Clark]

On your mobile phone you often lose your connection and the phone reconnects to either wifi or 3g depending. With Linphone how do we switch the call after a connectivity switch. Primarily we just need to be able to:

1. Reinvite the call from the trunk by sending it a new rtp payload that tells it our new ip address and port number (if applicable) where it needs to send the audio 
2. Re-STUN so we know what our new external ip address is since everyone these days is behind NAT. 

Any ideas how to do this? Thanks!
