MGCP Gateway using FXS/FXO registration problem

I have cisco Callmanager version 3.2 SpG and i have 3660 router Gateway.

in the 3660 router Gateway, i have one NM-HDA4FXS + 2*EM-HDA-4FXO.

I have configured in callmanger the gateway using mgcp protocol and i have selected

- in module slot 1 NM-HDA

- In Sub-Unit 0 NM-HDA-4FXS

- In Sub-Unit 1EM-4FXO-EM0

- In Sub-Unit 2 EM-4FXO-EM1

i have also configured each subunit.

I have configured the mgcp in the router

Problem :

The gateway (sub-unit) in the callmanager is not registred ! !!

I don't know why !!

Any comments ???

Re: MGCP Gateway using FXS/FXO registration problem

1.Can you ping the 3660 by it's hostname from the callmanager?

2.On the gateway configuration page, in the mgcp domain name field, you need to enter the router's hostame and not its ip address

3.Can you post the router's config...?

Re: MGCP Gateway using FXS/FXO registration problem

Edit the hosts or lmhosts file on the callmanager and add the router's hostname and ip address there. Then make sure you have configured the gateway in the callmanager using its hostname in the mgcp domain field.

>>In the MGCP Domain Name field, enter a name that identifies the gateway, from 1 to 64 characters. Use the Domain Name System (DNS) host name if it is configured to resolve correctly; otherwise, use the host name as defined on the Cisco MGCP gateway. If you are using the host name as it is configured on the Cisco IOS gateway, the name that you enter here must match exactly. For example, if the host name is configured on the gateway to resolve to vg200-1 and the IP domain name is not configured, enter the host name in this field (in this case, vg200-1). If the host name is configured on the gateway as vg200-1 and the IP domain name is configured on the gateway as cisco.com, enter vg200-1.cisco.com in this field.
