3rd party sip phone works fine, except through a C851

I am running some polycom phones through a Cisco 860 router (no CCME/SRST stuff).  Just a plain jane router, and it works fine, in fact any router I've tried, except the 851 works fine.

If I try and run the same phones through a Cisco 851 router (no CCME/SRST stuff), all my SIP authorizations get rejected.

Anything that could be cludging my SIP traffic come to mind?

I am having similar issues with the 851 and Polycom phones.  Did you ever figure this one out?
