You cannot change the H.323 port (TCP 1720) number.

In call manager go to Device > Gateway and under the H323 gateway configuration page there is a setting "Signaling Port" which you can change from 1720 to anything you want (make sure it doesn't overlap with something CUCM is already using, here's the port usage doc:

http://www.cisco.com/en/US/customer/docs/voice_ip_comm/cucm/port/8_0_2/portlist802.html).

I'll lookup the IOS side command to change the port number and get back to you.

On your dial-peers you can set a port in the session target ipv4:x.x.x.x:

Joemar2,

I din't know it was possible to change the TCP port number but now I now know it's possible.

I give you a 5 rating.
