[Spce-user] Wrong rtp interface selection on CF

Hi all

I faced a problem with rtp_interface selection when there's a CF. Scenario:

Incoming call from Peer1 which uses rtp_priv
Call to subscriber1 which uses rtp_ext and has a CFU or CFT o any CF
Forwarded call goes out via Peer2 which uses rtp_priv2

The call loads rtp_ext as caller rtp iface instead of keeping rtp_priv. Results
in no audio at all, of course.

when the call comes in from the sbc in the CF loop, the caller preferences are
set to the preferences of the subscriber. But for this particular setting
should be kept (custom header in the initial invite?) the ones of the original
caller, right?
