BD.

As you can see the T1 0/0/0:23 interface is active in layer 1,2(multi frame established) & 3,it means Q.931 signaling terminates at gateway and using backhauled technique q931 messages are going to CUCM server.

But in case of T1 0/2/1 port multi frames are not established in layer 2.So, its not configured properly & doesnt backhauling q931 messages to CUCM.
