Call Manager Redundancy?
	2008-03-06 07:47:12

We are discussing a disaster recovery plan which would include the placement of a Call manager in a remote location in case the site where our publisher resides was inaccessible/non functional. What is the best way to achieve this? ; Could we move the Pub to the remote location (connected by the MPLS) and keep the Sub in place at our main office or is it more complicated than that? ; Is there such thing as a two-Publisher scenario?  We currently have a Pub and Sub in our main location, a Sub at another location and an SRST site at our third office. Just a quick response would be very helpful so that I can begin to wrap my brain around this. ; Thank you!

CallManager v6/v7 have improved the functionality of services in the event a publisher is down. While moving a subscriber to the remote office is an option, I'd hate to have to travel to a remote site for an upgrade procedure. Consider using SRST and Unity Express with VM/AA/IVR as a backup solution as well. Of course, it all depends on how many people you have in the remote location and what services they are using.

Our main office has 800 people.  That's where the Pub (and Sub for that location) resides.  We would be looking at a scenario where both the Pub and Sub are down.

As long as your link is up, the phones at the main office should be able to connect to the sub in the remote office. That should keep things running. What are your gateways on? If they are on an ISR, you've got the h/w to configure SRST, you just need s/w licences.
