medium or high complexity for vwic card

[Fog Roni]

hi,everybody.

     I have a question about what's the case for vwic2/3-xmft-t1/e1 card needs to use medium or high complexity codec,as far as i know it use g.711 codec for local phone to TDM termination,but I don't know what's the case for this card needs to use g.722 or g.729 codec.

G.729 can be medium or high depending on codec variant of G729, G722 is the same as G711.

The best option is to simply leave the router in default flex mode and let it figure out the proper complexity for you depending on which codec is engaged on call per call basis.
