I trust you need
udp 16384 - 32767
tcp 1720
tcp 11000 - 11999
There are a number of references, including one attached in the archives,
and here is an additional link:

But I do not know where it is on documentation CD.
Best regards,
Alexei

If you are going to specify TCP port 1720 you might also specify TCP ports
11000 11999 using "range 11000 11999" for H.245, which is also part of
standard connect call setup under the H.323 architecture.
TCP port 1720 is only part of call setup and could be said (more
accurately) to be used by H.225.
The ITU H.323 specification describes an architecture that defines a set of
specific functions for framing and call control, codecs, and data
communications. The H.323 framing and call control functions are in turn
specified by the H.225 specification. H.225 defines the details of the RTP
and RTCP functions, such as logical framing, sequence numbering, error
detection and so forth.
H.245 provides the call control mechanism that allows H.323-compatible
terminals interconnection and specifies the signaling, flow control, and
channeling for messages, requests, and commands.

H.323 Protocol
Cisco CallManager communicates with H.323 gateways using TCP ports 1720
(H.225) and 11xxx
(H.245).

Also, for everyone's future reference, the following document lists other
possible ports, if you are using other types of voice traffic.

The following list serves as reference for the ports used by VoIP signaling
and control channels:
H.323/H.225 = TCP 1720
H.323/H.245 = TCP 11xxx (Standard Connect)
H.323/H.245 = TCP 1720 (Fast Connect)
H.323/H.225 RAS = TCP 1719
SCCP = TCP 2000-2002 (CM Encore)
ICCP = TCP 8001-8002 (CM Encore)
MGCP = UDP 2427, TCP 2428 (CM Encore)
SIP= UDP 5060, TCP 5060 (configurable)

Hope that clarifies.

If we are asking to create an access list to allow call setup, ring tone and
H.245 negotiation, where can I find the port numbers in the DocCD?
