Hi all,

The high-end Polycom models (VVX 1500 and SoundStation IP 6000/7000) have an 
overwhelmingly large number of codec options.  Many are simply bit rate 
variations of the same underlying codec.  sipXecs however exposes all options, 
thus cluttering the codec selection table.

I recently noticed this tidbit in the Polycom Admin Guide: "Note: Codecs with a 
default of Null are available for test purposes only and are not expected to be 
used in your deployment."

No Polycom model has a non-Null default for more than 8 codecs.  The Polycom 
"Voice/Codecs" configuration screen could be cleaned up considerably if we 
removed the codecs that are "for test purposes only".

For example the SoundStation IP 7000 complete list of available codecs would be:
 - Siren22 (64 kbps)
 - G.722.1C (48 kbps)
 - Siren14 (48 kbps)
 - G.722
 - G.722.1 (32 kbps)
 - G.711µ (PCM µ-law)
 - G.711A (PCM A-law)
 - G.729AB 

Would anyone miss the other codec options?
