The Polycom units open other "data" paths within the H323, H225 standards.

If you are limiting/blcking outside to inside traffic - you will be blocking communication streams.

Check your config, read the Polycom docs on getting VC untis working thru firewalls.

You may also want to check if the VC units are configured for NAT, if not this will also cause problems.
