[cisco-voip] Do CUBEs do transcoding by its own

[Nick Matthews]

Highly doubtful.  I can't say with any certainty that it makes sense for one
leg to be gsmefr in a normal scenario.  Is this a codec you use in your
environment?

Without seeing the dial peers that have been hit, it's really hard to say
what's going on.

To be absolutely clear - the only way a CUBE will change the codec on one
leg of a call to another is if transcoding is configured.  The transcoding
must be configured in a CME style, or it will not happen.  CUBE does not
reserve DSPs.
