[Asterisk-Users] Re: Polycom sound quality problems

[Wiley Siler]

Has the users hardware been assessed yet?  I cannot remember seing
anything regarding the hardware for this issue.

I am sure memory and processor speed will play a part if lots of calls
are active during the transcode...

It is not in the transport if it is sounding bad.... look and see if
there is any transcoding occuring from the IAX to the SIP. What codecs
are accepted on the AIX should be the Same codecs accepted on the SIP
channel ... and what codects are being used on each phone. This sounds
like a transcoding issue.
