Hi all. I want to configure up my remote office 7941 to use the g729 codec. My remoe office has a vpn tunnel and works fine using the g711 codec, but its too bandwidth heavy really (connecting to a 2801 ccme).
I've manually set the ephone to use the 729 codec, but I don't get any voice traffic so I assume that i need to configure transcoding somehow.
Thanks Nick. I always thought i'd need to transcode between the two codecs as ive never successfully made a 729r8 configured phone (7941 and the IP Communicator) talk to a 711 configured phone (7941). The phone will ring but no voice traffic happens.
When I revert both codecs back to 711 the conversations work.
So does this mean that i'll have to make all the phones in head office use the 728 codec (along with all remote IP Communicator's and 7941's ) then i'll be able to make the calls?
Changing the codec shouldn't give you no-way voice. There would be something else going on there causing that problem. You can try configuring 'mtp' under the remote phones to see if this makes a difference, or upgrading IOS.
