1

Create an H.323 trunk group and enter the H.323 trunk group view.

trunk-group name [ h323 h323-type ]

• In the peer gateway mode, the trunk group type is set to symmetrical.
• In the peer gatekeeper mode, the trunk group type is set to gk-gk.
• Registration mode:
  • In one-to-one registration mode, the trunk type on the gateway is set to gw-gk and that on the gatekeeper is set to register-gateway.
  • In one-to-many registration mode, the trunk type on the gateway is set to gw-gk and that on the gatekeeper is set to gatekeeper.

If a trunk group has been created, you can directly enter the trunk group view.

2

Configure the local media IP address or dynamic media IP address name.

media-ip { ip-address | addr-name addr-name-value }

-

3

Configure the gateway ID of the trunk group.

gwid gwid-value

This command is applicable to the H.323 trunks of the register-gateway and gw-gk types.

The H.323 trunk group of the gw-gk type must have a gateway ID configured, and the gateway ID must be the same as that on the peer H.323 trunk group of the register-gateway type; otherwise, authentication will fail.

4

Configure the remote IP address and port.

peer-address static primary-ip-address primary-port-value [ secondary secondary-ip-address secondary-port-value ]

This command is applicable to the H.323 trunks of the symmetrical, gw-gk, and gk-gk types.

The connection data on the trunk group must be the same as that on the peer.

5

(Optional) Configure IDs of the active and standby gatekeepers with which a gateway registers on the gateway.

gkid id secondary secondary-id

This command is applicable to the H.323 trunk groups of the gw-gk type.

6

Reset the H.323 trunk group.

reset

After creating or modifying an H.323 trunk group, run this command to make the configuration effective.

7

(Optional) Configure a technical prefix.

techprefix techprefix-value

When multiple H.323 trunk groups are configured, this step is required.

-

17

(Optional) Configure the description for the H.323 trunk group.
