Review request for Asterisk Developers and David Vossel.


Changes
-------

Added check that bridge is external channel and fixed the src/dst order in copy native formats.

Added dvossel to reviewers thank you for invaluable insight.


Summary
-------

This is a most annoying pain and tripped me up no end testing the T38 gateway patch for res_fax.

Scenario :-

i have a Linksys 2102 on a fax machine that uses G.729 and switches to ALAW on CNG and then negotiates T.38
this is awesome as i can now Chat/Fax from same terminal using most effective bandwidth [these are to be deployed
on sugar cane farms surrounding the kruger park here in south africa over wi-fi]

for testing purposes im using a local channel into T.30 fax app in res_fax.

Problem :-

when the device reinvites ALAW then T.38 it leaves the nativeformat on chan_local as G.729 this will not work
as it is transcoding the FAX from G.729 to SLIN this will not work and took me a while to spot the problem.

Soloution :-

Check the format on the proxy and adjust it if it changes this should be what Local does been a proxy of the channel
it should follow changes ...
