<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>

Redundancy?</DIV>
<DIV><BR></DIV>
<DIV><SPAN class=740504113-06032008><FONT face=Arial size=2>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!</FONT></SPAN></DIV>
