Summary:                    RTCP conflict avoidance not handled
Description: 
When trying to bridge a Gtalk outgoing call to a Gtalk incoming call that
uses the same IP address it fails.

The error it gives is:
[Jan 10 14:46:56] NOTICE[4520]: res_rtp_asterisk.c:2190 ast_rtp_read:
Unknown RTP codec 73 received from '95.21.226.219:58470'

In fact yes. I'm hairpinning the call because both end points belong to the
same LAN but in order to communicate they use an Asterisk server with an IP
in the public internet outside the LAN. Doing this is possible via SIP or
IAX but doesn't seem to work with chan GTalk.
Why is that an expected behavior? Doesn't Gtalk allow hairpinning?
