Re: [Linphone-developers] Cannot make call in local network without connectting to internet

[Simon Morlat]

Hi,

Linphone does not connect to the IP (it does not send any packet nor receive 
any response). The code you've seen is just a hack so that the kernel 
automatically sets the socket to the interface that connects to this 
(randomly choosen by me) public IP address.

However your patch is OK and I'm going to apply it to the cvs.

Thanks a lot.
