[Asterisk-Users] Polycom sound quality problems

[Eric Mason]

I'm having a problem with my Polycom phones and hoping someone else has 
experienced the same thing: Outbound calls are fine, and inbound calls 
originating from another SIP phone are fine, but inbound calls to the 
Polycom phone from an IAX channel sound like you're talking to a robot.  
The person on the Polycom sounds fine to the person on the IAX channel, 
however.  Inbound calls to our soft phones sound just fine.

Asterisk 1.0.5 on Debian (also had the problem with 1.0 on Fedora)
Polycom SoundPoint IP500 SIP
Sixtel is the IAX provider.

Anyone experience this before or have any ideas?

Thanks
Eric
