[cisco-voip] MTP won't register

[Brian Schultz]

CUCM 7.1.3.10000-11 and a 2951 router running 15.1(3)T1.  I am unable to get
the router to register as a transcode resource.  I've tried rebooting the
router and upgrading IOS.  Transcoder is built as an Cisco IOS Media
Termination Point.  Below is my router config.  I always see TCP_CONN_ERROR
for the SCCP status.  Am I missing something with the config here?  Maybe a
CUCM bug?  This one is really stumping me...
