Description (partial)

The MGCP process will remain in a Down state after the Router is back online from a reboot or power cycle. The following message is showing in the console logs while the Router is coming back online:

%MGCP_APP-6-GEN_INIT_NO_IP_INTF_FAILED: Suspended initialization of MGCP services. No IP interface up yet

After this message gets printed the MGCP process will not register with CUCM and remains in a Down state even when the IP Interfaces are in an UP state:

Router#show ip interface brief | exc unassigned
Interface              IP-Address      OK? Method Status                Protocol
GigabitEthernet0/0/0   x.x.x.x   YES NVRAM  up                    up  

Router#show ccm-manager
Load for five secs: 46%/0%; one minute: 47%; five minutes: 41%
MGCP Domain Name: 
Priority              Status                   Host
Primary             Down                     x.x.x.x
First Backup       None                     
Second Backup   None

- ISR4300 Router platforms.
- MGCP is configured without the "ccm-manager config" command.
- "mgcp bind control source-interface [interface]" command is configured pointing to a physical interface or sub-interface
- This only happens after a Reload or Power Cycle.
