[cisco-voip] what do i lose with the publisher being down?

[Ryan Ratliff (rratliff)]

The full list of user-facing features is in the docs, for example http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/7x/uc7_0/callpros.html#wp1043656.
CCMAdmin will be up but consider it readonly while the pub is out.

Brian covered services, though 7940s and 60s don't use internal directories so those guys will be out of luck for directories.

Make sure your pub isn't the only TFTP server available.

CFA is a user-facing feature/table so that does get updated when the publisher is down.  Same for all the dynamic tables.

You don't lose much.

I believe any write operations on the db will fail.
Example - trying to set CFA from phone.

Also I've run into a problem with EM where users attempted to logout from sub service URL and could not however that may have been a bug with version we were on so it may be a good idea to test that if that's a concern.

With internal services provisioning, phones now reach out to their subscriber for things such as Directories.

Make sure the publisher isn't the only MTP/MOH/CFB resource for any MRGLs.

Make sure the gateways are set to send calls to the subscriber primarily if using H.323/SIP.

I'm hoping I can get some "real world" comments here...

I need to take the publisher down in order to move it. From what I understand, for the most part, service will continue to operate. However, some things will not be available. From what I gather:

  *   CUCMUser pages will not be available
  *   CUCMAdmin pages will not be available
  *   Services Subscription listing when Services URL pointing to the publisher

What else will be unavailable? We are not using extension mobility.


If I program the service URL of a phone to point to a different server, will the phone continue to call that separate server? Or does it need the publisher to get that information first?


Thoughts?
