Port Numbers used by MCU3545-24 - To configure Firewalls

Unanswered Question
Jun 16th, 2009

We are looking for a document or advise on what TCP and UDP ports are utilised by the MCU3545-24 which also have EMP blades installed on them.


More specifically, the following:

TCP Signalling (H.225) --- have manually set via the MCU GUI

TCP CallControl (H.245) --- seems to be a random high port range in the 1xxx range ??

UDP RTP Audio ---- seems to be a random high port range in the 6xxx range to/from the MCU blade and endpoint?

UDP RTP Video ---- seems to be a random high port range in the 10xxx range to/from the EMP blade and endpoint ??

Nowhere can we see this documented on either Cisco or RADVision's websites
