Video Conferencing through Firewall

I managed to let the following three equipments talk to each other:
-Polycom
-Tandberg
-Lifesize

by opening the following ports in the firewall:
----------------------------------------
TCP: 1719, 1720, 3230-3270, 5555-5587
UDP: 1719, 1720, 3230-3285, 2326-2387
----------------------------------------


And here is a link to a good document in Tandberg.com:
[Tandberg & Security (pdf file)]

The following TCP and UDP ports are relevant for TANDBERG systems.
Port Number Service Protocol
21 FTP/control *TCP
23 Telnet *TCP
80 HTTPd *TCP
123 NTP *UDP (Codec Only)
161 SNMP/queries *UDP
162 SNMP/traps UDP
443 HTTPs TCP
963 Netlog TCP
970 Streaming/RTP UDP
971 Streaming/RTP UDP
972 Streaming/RTP UDP
973 Streaming/RTP UDP
1026 FTP/data TCP
1027 VNC TCP
1719 H323/RAS UDP
1720 H323/Q931 *TCP
2326-2373 (2837)** H323/RTP UDP
5555-55xx (5587)** H323/H.245/Q.931 TCP
The first outgoing call uses 5555 for outgoing Q.931 and 5556 for H.245, next uses 5557 for
Q.931 and 5558 for H.245, etc. Each incoming H.323 call uses the next available port for
H.245. Disconnecting a site in a call will not free up available 55XX ports until the whole
conference is down.
