Cisco mgcp gateway not registering

More specifically, it disects an MGCP Message in order to better understand each of their components, and what makes them important. This document utilizes configuration examples as well as debug and show command outputs as reference points.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared default configuration.

If your network is in production, ensure that you understand the potential impact of any command. The entire control intelligence is controlled by a Call Agent who instructs the endpoint what action to take once an event is detected.

An identifier is needed per endpoint for the Call Agent to be able to determine whom it needs to send an event, or where an event comes from. Endpoints Identifiers have two main components:. You only need to add this configuration to start the registration process, as the rest of the configuration is then downloaded from CUCM:.

Now that you have selected the hardware and protocol used, you need to configure the Domain NameCisco Unified Communications Manager Groupand the Module Information. These are the major fields that are required to register an endpoint via MGCP. The Domain Name is comprised of 1 to 2 parts. At a minimum in the Domain Name field you need to enter the Host Name of the router.

In my scenario, the Host Name is:. However, if you have a domain name configured on the gateway, you need to configure the Fully Qualified Domain Name of this device:. Now, you must hit Save. This updates the page and allow you to select a Subunit now.

You can now see your configurable ports:. Once you select a port you are prompted to configure the port type:. In this case, you select POTS. Once this is selected, you can enter all the necessary values for the device information like you would for any other Call Manager Endpoint. The only required field is Device Pool, however you might want to enter values for things such as a Calling Search Space. Once you have done this, you can then click Save. You can now associate a DN with this port, save, and the apply the configuration.

Once this is done, back at the port configuration page you can now see the port as registered:. The response from the Gateway is an ACK with the endpoints capabilities. This is a sample debug output:.

When you troubleshoot MGCP there are some helpful show commands and debugs that you can view in order to determine why registration or a call has failed. You can check this via the show command show ccm-manager or show mgcp :. These commands have been shortened to contain just the pertinent output. For additional information, you can look at these show outputs:.

Resolution In order to resolve this issue, complete these steps: In order for the gateway to register with Cisco CallManager, use the minimum configuration required: mgcp mgcp call-agent CallManager IP Address ccm-manager mgcp If the gateway is configured as shown and it still does not register, make sure there is IP connectivity to Cisco CallManager.

The easiest way to do this is to issue the ping command from the gateway with the IP address of Cisco CallManager. Note: If the host name of the gateway is changed, the MGCP domain name changes as well, which makes the gateway unable to register with Cisco CallManager. Make sure that if the host name of the gateway is changed, the MGCP domain name that is configured in Cisco CallManager is also updated.

Lab 1.5b MGCP Gateway

Endpoints are references to specific voice ports on a gateway while call-agents are the control devices that administer the gateways. Endpoints are any of the voice ports on the designated gateway. Ports on gateways are identified by endpoints in very specific ways. It is important to note that gateways can have multiple endpoints dependent on the number of ports it contains, and that the endpoints are case insensitive.

This is a sample endpoint and an analysis of each portion of it:. This name is used to designate that the type of endpoint is analog. This value changes dependent on what type of endpoint is in use. For example, if a DS3 interface is used, this value would be "ds3". More on the digital endpoint specification is given later in this document. This is the slot number on the chassis that holds the voice network module. If the gateway has been configured with a domain name, it is appended to the hostname as seen in this example.

Note the only difference is the trunk type and the B-channel. The trunk type designates what type of trunk the endpoint describes. Some examples of valid trunk types are ds1, ds3, e1, and e3. The B-channel specifies which B-channel on the trunk this endpoint is associated with. Call agents are external control devices in a voice system. Cisco CallManager is the call agent referenced in this document. In MGCP, the call agent is the device that has complete control of the gateway.I checked the router name domain name everything is correct nothing changed.

Did you try to make a call to make sure it's not just the wrong status being shown??? The problem is I cannot test. Reason being our existing office is going to relocate to this new site where this gateway is. I have seen same symptoms in past with mgcp gw and if i try to remove and add back the bind commands it had worked for me.

If the issue was with your RIS service there will be lot of other devices showing the same way - for example phones, they will be showing unregistered in CUCM but working otherwise. If that's the case restarting RIS service will help.

To rule out RIS service issue you can create a route pattern say your mobile and point to this gateway and make a call to this number. As said before RIS service will have no impact on the call processing, you can restart to rule it. Yes I can ping the cucm I tried to change the name on the cucm to see whether the router will get registered or not and it is not registering with cucm. When I put the correct name on cucm the router get registered immediately however the status on cucm still says unregistered.

Here is the out put you requested. I did ask you to remove and add them back. Am facing the same issue. As you suggested Terry, i followed with your steps but no luck. I have attached output of. Pls suggest.

If your network is live, make sure that you understand the potential impact of any command.

Refer to Cisco Technical Tips Conventions for more information on document conventions. The VG starts with a default configuration, as it comes shipped. The mgcp call-agent command is used to configure the address and protocol of the call agent for MGCP endpoints on a media gateway. This command can be used to specify the version of the protocol used. For more information, refer to mgcp call-agent. Always issue this command in uppercase unless you know that your software release is not case-sensitive.

Look at the output of the show running-config command in order to check whether your software release is case-sensitive. Issue the command on only one of these ports. You also need to create a default network, or gateway of last resort. This step shows how to perform both tasks:.

It behaves more like an end station client as far as IP connectivity is concerned. Default commands do not usually show up in a Cisco router configuration. The VG Cisco IOS images override this default behavior by hardcoding the no ip routing command into the initial configuration. This configuration is created when the image is booted:.

Refer to Cisco Technical Tips Conventions for more information on document conventions. These steps do not need to be performed in the order in which they appear. The show commands are useful because they display the current status of the configuration as well as verify that the changes that you made took effect. This command verifies the active and redundant configured Cisco CallManager servers.

It also indicates if the gateway is currently registered with the Cisco CallManager. Use this command to verify the status of the router MGCP parameters. All the other parameters are left at their default behavior in this configuration. Use this command to show the voice ports endpoints that are under MGCP control in the router. This command verifies which voice ports have been bound to the MGCP application.

Use this command to display any active MGCP connections. This tells you which port on the router is the endpoint in the call. Use this command to verify the current status and configuration of the voice ports on the router.

Use the no battery-reversal command on FXO ports to disable this action. On FXO ports that do not support battery reversal, the battery-reversal command can cause unpredictable behavior, while the battery-reversal answer command prevents calls from being answered.

Use the no battery-reversal command to ensure that battery reversal answer is disabled on FXO ports that do not support battery reversal. Use these commands when you experience problems that you believe are not related to configuration errors or hardware problems.

Keep an example of each debug command from a working configuration to use for comparison when you experience problems.
