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

[Roy Huang]

Hi,

When I test two linphones directly in local network without connecting
them to internet, they cannot find each other.

I find that is caused by it trying to find the network interface by
connecting to "15.128.128.93", if linphone cannot connect to the ip,
it will cannot find its own network interface. That seems like a
little strange. How about some day the server with the ip down?

The following patch makes two linphone work in local network.
