Table: Task Roadmap
Task Reference

(Optional) If your gatekeeper is not yet configured or defined in your call-control device, then configure your gatekeeper.

See the Configuring the Gatekeeper: Identifying the Hostname, Zone, and Technology Prefix.

Configure your particular call-control device.

Configure Cisco Unified MeetingPlace Express to integrate with your chosen call-control device.

See the Configuring Cisco Unified MeetingPlace Express: Adding the Gatekeeper.



Configuring the Gatekeeper: Identifying the Hostname, Zone, and Technology Prefix

If your gatekeeper is already configured with a hostname, zone, and technology prefix, do not perform this task.


Before You Begin
Restrictions
  • This task is performed in the Cisco IOS command-line interface (CLI) of the gatekeeper.


Procedure
  1. On the Cisco router, enter privileged EXEC mode or any other security level set by a system administrator. Enter your password if prompted.
    Router# enable
  2. Enter global configuration mode.
    Router# configure terminal
  3. Enter interface configuration mode.
    Router(config)# interface type number
  4. Configure the IP address and subnet mask used by this gateway.
    Router(config-if)# ip address [ip-address] [subnet-mask]
  5. (Optional) If you configured a Fast Ethernet interface, configure duplex operation as auto, which specifies the autonegotiation capability. The gateway automatically operates at half or full duplex depending on environmental factors, such as the type of media and transmission speeds for the peer routers, hubs, and switches used in the network configuration.
    Router(config-if)# duplex auto
  6. (Optional) If you configured a Fast Ethernet interface, configure the speed for this gateway.
    Router(config-if)# speed auto
  7. Configure this interface as an H.323 gateway interface.
    Router(config-if)# h323-gateway voip interface
  8. Define the name and location of the gatekeeper for this gateway.
    Router(config-if)# h323-gateway voip id [hostname] ipaddr [ip-address]
  9. Configure the H.323 name of the gateway identifying this gateway to its associated gatekeeper.
    Router(config-if)# h323-gateway voip h323-id hostname
  10. Define the technology prefix that the gateway will register with the gatekeeper.
    Router(config-if)# h323-gateway voip tech-prefix prefix
    • prefix-Defines the numbers used as the technology prefixes. Each technology prefix can contain up to 11 characters. Although not strictly necessary, a pound (#) symbol is frequently used as the last digit in a technology prefix. Valid characters are 0 though 9, the pound (#) symbol, and the asterisk (*).
  11. Exit the current mode.
    Router(config-if)# exit
  12. Enter gatekeeper configuration mode.
    Router(config)# gatekeeper
  13. Configure the zone name and the name of the domain served by this gatekeeper.
    Router(config-gk)# zone local zone-name domain-name [ip-address] [port]
    • Optionally, you may specify the IP address of one of the interfaces on the gatekeeper. When the gatekeeper responds to gatekeeper discovery messages, it signals the endpoint or gateway to use this address in future communications.
    • Set the gatekeeper port for Registration, Admission, and Status (RAS) signaling to 1719. This is the default.
  14. Configure the technology prefix, also called the gateway-type prefix.
    Router(config-gk)# gw-type-prefix type-prefix
  15. End your configuration session by exiting to privileged EXEC mode.
    Router(config-gk)# end


Example

In the following Cisco IOS configuration example, the gatekeeper router hostname gk-1.example.com is also used as the zone name. Matching these names is not necessary but simplifies administration.

 !

interface FastEthernet0/0 ip address 1.1.100.200 255.255.0.0 duplex auto speed auto h323-gateway voip interface h323-gateway voip id gk-1 ipaddr 10.1.100.200 1719 h323-gateway voip h323-id ipipgw_core h323-gateway voip tech-prefix 1# ! gatekeeper zone local gk-1.example.com 1.1.100.200

Configuring Cisco Unified Communications Manager Express and Other Standards-Based H.323 Call-Control Devices: Configuring the Dial Peer

This topic describes how to enable your call-control device to route calls to Cisco Unified MeetingPlace Express by configuring a dial peer. Configuring dial peers is the key to implementing dial plans and providing voice services over an IP packet network. Dial peers are used to identify call source and destination endpoints and to define the characteristics applied to each call leg in the call connection.
