A T1 does not connect to CUCM. If there were any active calls you would see.
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
6 Active Layer 3 Call(s)
CCB:callid=7D99, sapi=0, ces=0, B-chan=3, calltype=VOICE
CCB:callid=7DB8, sapi=0, ces=0, B-chan=16, calltype=VOICE
CCB:callid=7DE9, sapi=0, ces=0, B-chan=20, calltype=VOICE
CCB:callid=7DEA, sapi=0, ces=0, B-chan=21, calltype=VOICE
CCB:callid=7DEB, sapi=0, ces=0, B-chan=22, calltype=VOICE
CCB:callid=7DED, sapi=0, ces=0, B-chan=1, calltype=VOICE
CCB:callid=7DEE, sapi=0, ces=0, B-chan=2, calltype=VOICE
I agree with the answer DE.
STATE MULTIPLE-FRAME-ESTABLISHED
Is indication of successful connection with CUCM, it is part of CCIE Collab Lab as well.

From output of this command you cannot tell anything about CUCM and it does not have anything in common with it 🙂
