Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

Configuring Static Nodes

In some cases, the registration information is not accessible for a terminal or endpoint from any gatekeeper. This inaccessible registration information may be because the endpoint does not use RAS, is in an area where no gatekeeper exists, or is in a zone where the gatekeeper addressing is unavailable either through DNS or through configuration.

These endpoints can still be accessed via a gatekeeper by entering them as static nodes. To enter the endpoints as static nodes, obtain the address of the endpoint and then use the following commands beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Router(config)# gatekeeper

Enters gatekeeper configuration mode.

Step 2

 

 

Router(config-gk)# zone local gatekeeper-name

Specifies a zone controlled by a gatekeeper.

 

domain-name [ras-IP-address]

For an explanation of the arguments, see Step 2 of the

 

 

 

 

configuration task table in the “Starting a

 

 

Gatekeeper” section on page 304.

Step 3

 

 

Router(config-gk)# alias static ip-signalling-addr

Creates a static entry in the local alias table for each

 

[port] gkid gatekeeper-name [ras ip-ras-addr port]

E.164 address. Repeat this step for each E.164

 

[terminal mcu gateway {h320 h323-proxy voip}]

address you want to add for the endpoint.

 

[e164 e164-address] [h323id h323-id]

 

 

 

 

The keywords and arguments are as follows:

 

 

• ip-signalling-addr—Specifies the IP address of

 

 

the H.323 node, used as the address to signal

 

 

when establishing a call.

 

 

• port—(Optional) Specifies the port number other

 

 

than the endpoint call-signaling well-known port

 

 

number (1720).

 

 

• gkid gatekeeper-name—Specifies the name of

 

 

the local gatekeeper of whose zone this node is a

 

 

member.

 

 

• ras ip-ras-addr—(Optional) Specifies the node

 

 

remote access server (RAS) signaling address. If

 

 

omitted, the ip-signalling-addrparameter is used

 

 

in conjunction with the RAS well-known port.

 

 

• port—(Optional) Specifies a port number other

 

 

than the RAS well-known port number (1719).

 

 

• terminal—(Optional) Indicates that the alias

 

 

refers to a terminal.

 

 

• mcu—(Optional) Indicates that the alias refers to

 

 

a multiple control unit (MCU).

 

 

• gateway—(Optional) Indicates that the alias

 

 

refers to a gateway.

 

 

• h320—(Optional) Indicates that the alias refers

 

 

to an H.320 node.h320—(Optional) Indicates

 

 

that the alias refers to an H.320 node.
