Re: [Linphone-developers] iPhone background behaviour / SIP over TCP and RTP over UDP?

[Martin Hörlin]

The behaviour on the Android version is that the UDP/TCP/TLS option only 
affects the SIP traffic and that the RTP always uses UDP for transport. 
I would assume it is the same for the Iphone version.
