HELLO EVERYBODY.
I have some problems between CallManager 4.2(3) and gateway 2851 with 5 E1s, I see that the gateway register to CallManager but I receive alarms on the EVENT VIEWER of the CCM that all E1s that the b-channel out of service, also there is an Transient connection attempt with the following explanation:
A conection was established and immediately dropped before completion registration. Incomplete registration may indicate a device is rehoming in the middle of registration.
Here is a show ccm, where you can see the registration ok:
