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:

Unknown RTP codec 73 received from '95.21.226.219:58470'

Yes, I'm using two different gtalk accounts.
What I'm doing is this:

phone1 --> LAN  --> Internet --> Google--> Internet--> Asterisk --\
phone2 <-- LAN  <-- Internet <-- Google <-- Internet <----------/

But I think Google does shuffling and it all ends up being:

phone1 --> LAN  --> Internet--> Asterisk --\
phone2 <-- LAN  <-- Internet <----------/

So, If I understand the term correctly, I does look like hairpinning to
me.
