This KB article is the exact text that I read in the Netmeeting Resource Kit
posting.. If you read down through what you posted, you will see that it
claims those ports for outbound calls.. my question was regarding inbound
calls only, specifically inbound for program sharing/whiteboard etc only...

I appreciate that though..

regards,
bill

From How to Establish NetMeeting Connections Through a Firewall [Q158623]

NetMeeting uses the following Internet Protocol (IP) ports:

   Port Purpose
  -------------------------------------
  389 Internet Locator Server [Transmission Control Protocol (TCP)]
  522 User Location Server (TCP)
  1503 T.120 (TCP)
  1720 H.323 call setup (TCP)
  1731 Audio call control (TCP)
  Dynamic H.323 call control (TCP)
  Dynamic H.323 streaming [Realtime Transport Protocol (RTP) over User
Datagram Protocol (UDP)]

To establish outbound NetMeeting connections through a firewall, the
firewall
must be configured to do the following:

 - Pass through primary TCP connections on ports 522, 389, 1503, 1720 and
1731.

 - Pass through secondary UDP connections on dynamically assigned ports
  (1024-65535).
