MGCP Registration Problems with Cisco 3725 and CCM6.1

I have some problems in registering my MGCP gateway into the cisco call manager . I have read a similar post here:
but it was not useful in my case.
Show part of running config of My MGCP gateway:
HQ#show running-config
Building configuration...

Current configuration : 1757 bytes
version 12.4
service config
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
hostname HQ
ip domain name site1.com
ip host ccm-sdk
interface FastEthernet1/0
 ip address
 duplex auto
 speed auto
ccm-manager mgcp
ccm-manager music-on-hold
ccm-manager config server
ccm-manager config
mgcp call-agent 2427 service-type mgcp version 1.0
mgcp dtmf-relay voip codec all mode out-of-band
mgcp rtp unreachable timeout 1000 action notify
mgcp modem passthrough voip mode nse
mgcp package-capability rtp-package
mgcp package-capability sst-package
mgcp package-capability pre-package
no mgcp package-capability fxr-package
no mgcp timer receive-rtcp
mgcp sdp simple
mgcp fax t38 inhibit
no mgcp explicit hookstate
mgcp rtp payload-type g726r16 static
mgcp profile default
Also I have thses outputs:
HQ#show ccm-manager
MGCP Domain Name: HQ.site1.com
Priority        Status                   Host
Primary         Registering with CM
First Backup    None
Second Backup   None

Current active Call Manager:    None
Backhaul/Redundant link port:   2428
Failover Interval:              30 seconds
Keepalive Interval:             15 seconds
Last keepalive sent:            23:59:59 UTC Feb 28 2002 (elapsed time: 01:41:32)
Last MGCP traffic time:         01:41:04 UTC Mar 1 2002 (elapsed time: 00:00:27)
Last failover time:             None
Last switchback time:           None
Switchback mode:                Graceful
MGCP Fallback mode:             Not Selected
Last MGCP Fallback start time:  None
Last MGCP Fallback end time:    None
MGCP Download Tones:            Disabled
TFTP retry count to shut Ports: 2

Unfortunately this process is in registering mode and doesn't change. These are the debug ccm messages:
*Mar  1 01:42:04.075: cmapp_mgr_process_ev_active_host_failed: Active host 0 ( failed
*Mar  1 01:42:04.075: cmapp_mgr_check_hostlist: Active host is 0 (
*Mar  1 01:42:04.075: cmapp_try_fallback(set_to_mode=ON)
*Mar  1 01:42:04.079: cmapp_shut_backhaul: backhaul link shutdown is not configured
*Mar  1 01:42:04.079: cmapp_try_fallback: fallback is not configured
Also, I attached my add gateway in ccm6 page here...I don't understand what is the problem...

I finally solved the problem and still did not get any response from here!!!
alihashemiAuthor Commented:
I just removed configurations about domain name and used HQ(my router name) in the CCM gateway list and problem was solved.
I had the same probelm .
Could you please explain more?
We were getting a trap every minute to our NMS system:

sysUpTime=141 days 21 hours 46 minutes 4.41 seconds

We removed the "ip domain name acme.com" and then the router registered.
Thanks for your help alihashemi
