[Asterisk-Users] Attempting native bridge .......

[Chad Scott]

The audio is carried on two RTP streams: one for each direction.  Is it 
possible those streams are being blocked by a firewall or something of 
the sort?

The "attempting native bridge" message means that Asterisk is bridging 
the two calls together without doing any codec translation... uLaw to 
uLaw, for instance.

If the two phones were using "reinvite" you wouldn't see this message 
because there would be nothing for Asterisk to bridge: the two phones 
are chatting to one another.
