I applied the DST patch to our servers today (CUCM 6.0(1)) and rebooted the publisher and then the subscriber. Later, I noticed that phones are all registered to the publisher, which is 2nd in our CMGroup list. Upon further investigation, I noticed that the callmanager service is activated but not running on the subscriber. I can restart it and it will run for about 20 to 25 seconds but then stops again. I rebooted the subscriber, but that did not resolve the issue.
Any ideas on how to dig further into this or on what might be causing it?
Hmmm Try rebooting the SUB again. If that does not work, I would recommend to enable detailed SDI and SDL CCM traces on the SUB and then try to restart the service? Once it stops, gather the traces from RTMT. Also check the Application logs to see if there are any related errors or any replication issues.
Seems like the port used by CCM Service is used by another service (You can see which port is used under System--> Unified CM), but if you did not make any change this should not be the issue.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
