[asterisk-users] Polycom 550 IP SoundStation Fuzzy Voice Quality

[Mike Coakley]

I'm setting up a new Asterisk system on a Dell server and I'm getting  
"fuzzy" voice between the Polycom IP SoundStation 550 and the Asterisk  
server. I've checked all of my codec settings and both the Asterisk  
and the Polycom agree on u-Law encoding. I'm using the latest release  
of the Asterisk code (1.4.17) and other software. If I call between  
phones (i.e. two Polycom's) everything is crystal clear so it doesn't  
appear to be a Polycom issue.

Here is the current information on the Polycom phone:

SoundPoint IP 550
Assembly: 2345-12500-001 Rev: A
BootBlock 2.7.0 (12500_001)
BootRom: 4.0.0.0423
SIP: v.2.2.0.0047
PolyDSP Titan Mem1 FS3 v1.7.0.0057

Here is my SIP config:

[2000]
type=friend
username=2000
password=sip-access
dtmfmode=rfc2833
mailbox=2000 at office
disallow=all
allow=ulaw

Any help would be appreciated.

Thanks,

Mike
