I have been playing with linphone on three machines on an internal asterisk
network and have discovered some strange behaviour.

Machine A - PC running Linux (12.04 kernel) and linphone 3.3.2
Machine B - HTC Desire HD running Android 2.3.7 (Cyanogenmod) and linphone
2.1.2
Machine C - Motorola Xoom 2 running Android 4.0.4 and linphone 2.1.2
Machine X - PC server running Linux and asterisk 1.2.17 - yes, it's old but
it works

All machines have materially identical SIP configs and all machines
register to X with fixed ports (5060) with no problem.

When A dials B a fully functioning bridged connection is established via X
and sound passes both ways.

When A dials C a connection is established via X but there is no RTP stream
from X to C (there is upload packets from C to X) though asterisk reports
that the connection has been bridged.  However, as A is in the process of
dialling C, so C sends a few short UDP packets from port 7078 and port 9078
to 91.121.209.194 port 3478. That IP address comes up as ovn.net based in
France.  Machine B does not exhibit this behaviour.  Seems a bit sus to me.

Anyone got a clue WTF.
