How to Configure a Cisco Call-Control Device in an H.323 Environment
This topic describes how to add Cisco Unified MeetingPlace Express as an H.323 gateway to a Cisco call-control device other than Cisco Unified Communications Manager. This includes Cisco Unified Communications Manager Express and Cisco IOS software voice-enabled routers.

Configuring a Cisco Call-Control Device in an H.323 Environment: Adding the Gateway
Before You Begin
Restrictions
- This task is performed in the Cisco IOS command-line interface (CLI) of the router. For more information about the Cisco IOS commands used in this procedure, see the Cisco IOS Commands Master List for your Cisco IOS software major release.
Procedure
- 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
- Enter global configuration mode.
- Router# configure terminal
- Enter interface configuration mode.
- Router(config)# interface type number
- Configure the IP address and subnet mask used by this gateway.
- Router(config-if)# ip address [ip-address] [subnet-mask]
- (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 {full | half | auto}
- (Optional) If you configured a Fast Ethernet interface, configure the speed for this gateway.
- Router(config-if)# speed {10 | 100 | auto}
- Set the source IP address to be used for this gateway. This command binds all H.323 messages from the gateway to this IP address.
- Router(config-if)# h323-gateway voip bind srcaddr [ip-address]
- Exit the current mode.
- Router(config-if)# exit
- Proceed to the Configuring a Cisco Call-Control Device in an H.323 Environment: Configuring the Dial Peer.
Example
The following example displays an H.323 gateway configuration with an IP address of 10.10.10.1. Both duplex operation and interface speed are configured for autonegotiation and all H.323 messages are bound to this IP address.
!
interface FastEthernet0/0
ip address 10.10.10.1 255.255.255.0

Configuring a Cisco Call-Control Device in an H.323 Environment: 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.
Before You Begin
- Read the Integrating with Cisco Unified Communications Manager Express and Other Standards-Based H.323 Call Control Devices
- Complete the task described in the Configuring a Cisco Call-Control Device in an H.323 Environment: Adding the Gateway.
Restrictions
- This task is performed in the Cisco IOS command-line interface (CLI) of the router. For more information about the Cisco IOS commands used in this procedure, see the Cisco IOS Commands Master List for your Cisco IOS software major release.
Procedure
- 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
- Enter global configuration mode.
- Router# configure terminal
- Enter dial peer voice configuration mode and define a remote voice over IP (VoIP) dial peer.
- Router(config)# dial-peer voice number voip
- number-is one or more digits that identify the dial peer. Valid entries are from 1 to 2147483647.
- voip-indicates a VoIP peer that uses voice encapsulation on the IP network.
- (Optional) Provide a comment or a description to help you remember what is attached to this interface.
- Router(config-dialpeer)# description string
- Route calls to the Cisco Unified MeetingPlace Express server.
- Router(config-dialpeer)# destination-pattern digits
- digits-indicates the numbers that match the destination pattern.
- Configure the IP address of the Cisco Unified MeetingPlace Express server.
- Router(config-dialpeer)# session target ipv4:ip-address
- Configure the router to use dual tone multifrequency (DTMF) relay to transport DTMF digits.
- Router(config-dialpeer)# dtmf-relay h245-alphanumeric
- Configure the router to use a particular codec.
- Router(config-dialpeer)# codec [g711ulaw | g711alaw | g729 ]
- Disable voice activity detection (VAD) for the calls using this dial peer.
- Router(config-dialpeer)# [no] vad
- Exit the current mode.
- Router(config-dialpeer)# exit
- Proceed to the Configuring Cisco Unified MeetingPlace Express: Connecting to a Standards-Based H.323 Call-Control Device.
Example
The following example displays dial peers that were configured to direct calls to a primary Cisco Unified MeetingPlace Express number and an alternate Cisco Unified MeetingPlace Express number. The Cisco Unified MeetingPlace Express IP address is configured as 10.10.10.4.

Configuring Cisco Unified MeetingPlace Express: Connecting to a Standards-Based H.323 Call-Control Device
This topic describes how to configure Cisco Unified MeetingPlace Express to connect directly to a call-control device in an H.323 environment. This topic supports the following call-control devices:
- Cisco Unified Communications Manager Express and Cisco Unified CallManager Express
- Cisco IOS software voice-enabled router
- Third-party standards-based H.323 call-control devices
Before You Begin
- See the Prerequisites for Integrating with Cisco Unified Communications Manager Express and Other Standards-Based H.323 Call Control Devices.
- If you are integrating with Cisco Unified Communications Manager Express or a Cisco IOS software voice-enabled router, complete the tasks described in the How to Configure a Cisco Call-Control Device in an H.323 Environment.
- If you are using a third-party standards-based H.323 call-control device, configure your device as outlined in your product documentation.
- When you modify the parameters on the H.323 Configuration page, Cisco Unified MeetingPlace Express reinitializes H.323 signaling with the call-control device. During the reinitialization process, which can take up to 2 minutes, calls and voice meetings may be affected.
Procedure
- Log in to Cisco Unified MeetingPlace Express and click Administration.
- Click System Configuration > Call Configuration > H.323 Configuration.
- Configure the fields in Table: Required Configuration for H.323 Configuration Page on Cisco Unified MeetingPlace Express for Integration With a Call-Control Device Without a Gatekeeper.
Table: Required Configuration for H.323 Configuration Page on Cisco Unified MeetingPlace Express for Integration With a Call-Control Device Without a Gatekeeper
| H.323 Configuration Page Field | Required Value |
|---|---|
|
Yes | |
|
1720 (default) | |
|
No | |
|
IP address of your call-control device.
| |
|
IP addresses of other call-control devices in the cluster, if any. Note: If the primary call-control device goes down, Cisco Unified MeetingPlace Express cannot complete dialed-out calls without a gatekeeper. These fields enable only incoming calls to be routed by the failover call-control devices. |
4. Click Save.
5. Click System Configuration > Call Configuration > Dial Configuration.
6. Set the Outdials field to H.323.
7. Click Save.
8. Test this integration by placing a call from any phone to the phone number that is used to access the Cisco Unified MeetingPlace Express system. You should hear the "Welcome to Cisco Unified MeetingPlace Express" greeting.
