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:
https://secure.experts-exchange.com/index.jsp?srid=7K/3ChQoB4Ji73zJZyYcTQ%3D%3D&redirectURL=/Networking/Telecommunications/IP_Telephony/VoIP/Q_23131537.html&rsid=20#a20804803
but it was not useful in my case.
Show part of running config of My MGCP gateway:
HQ#show running-config

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 (172.16.1.5) failed
*Mar  1 01:42:04.075: cmapp_mgr_check_hostlist: Active host is 0 (172.16.1.5)
*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...
