I need a little help. I have an Audiocodes 118 fxs set up on trixbox along with a Mitel 4330.
I am using g729 native on both devices, therefore I should not be transcoding the calls.
When I check the codec status, it says I am decoding in one direction.
How can this be.
Here is what I am seeing.

0/1 encoders/decoders of 1 licensed channels are currently in use
What I noticed right away was this on the audiocodes side.
Their Codec Capability: 268
Joint Codec Capability: 256
Why do you thing these are different, and could that be why Trixbox is decoding in one direction?
It is my understanding that if both endpoints are g729, that no liscensed codecs will be used.
TIA.
