That's strange. We are using some Polycom 300 and they work ok. No STUN support and sometimes a very erratic registration pattern, but except from that, they seem to perform ok. They interoperate with sipuras, grandstreams, sjphone, cisco gw, xlite, etc. g-)

harry,
we tried polycom video phones a month or so ago and their sip implementation was worst i had seen so far. the phones didn't support digest authentication and we were also hit the problem you mentioned with domain in request-uri. i suggest to junk those phones before their sip implementation is closer to rfc3261.
