[Asterisk-Users] Polycom Soundpoint 500

[Brent Davidson]

I have a Polycom Soundpoint IP 500 that I have been using with Asterisk
for a few weeks.  It has been working OK, no major problems other than a
freeze up every now and then, until today.  The power apparently went
out last night and for some reason the phone appears to be working but I
keep getting the following errors repeating over and over in my Asterisk
log file (IP's X'ed out):

The phone has two lines, extension 7202 and 7203.  I don't receive any
messages regarding 7203, and the two sip profiles are identical in the
sip.conf file (with teh exception of substituting 7202 for for 7203) and
I have retyped the password into the phone more times than I can count. 
Now the odd thing is that the phone can make and receive calls, they are
just very choppy when calling IAX extensions.  When the calls go to/from
the Polycom from/to a Zap channel, the calls are perfectly clear.

I am completely lost at this point.  Any ideas?

Thanks,
