Re: [Linphone-developers] Implement iOS Background Mode for incoming call

[Xaree]

According to the official documents for iOS development 
(http://www.linphone.org/docs/liblinphone/group__IOS.html): "liblinphone 
automatically configures SIP socket for voip".

I don't know how to check whether the linphone uses TCP socket. Any idea?
