Line 303095 is probably relevant, too.  What codec is the phone  
configured to try first?  It looks like the phone is trying to use  
something asterisk doesn't understand, or is not configured for.   
Maybe set the phone to ulaw instead.

Also, what dtmfmode are you using?  Can we look at your sip.conf from  
asterisk, and the config files for your Polycom phone?
