[cisco-voip] Call Manager Redundancy?

[Lelio Fulgenzi]

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.

  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!
