[cisco-voip] Multiple CallManager Groups and Registration?

[Dustin S. Fowler]

John,

 

If I understand this right you have two sites. Each one with a CUCM.

 

If this is the case you could create a new CMGroup and change each Device
Pool affected to the new group. 

 

I have in production where one location always registers to the pub and the
HQ registers to the Sub.

 

In doing this you will still have server failover and the phones will not
have to reregister if the WAN link goes down.

We've been having issues over the past several months with our WAN
connection going down, and all of our phones at the remote office trying to
register and run across our backup 10meg line, which of course isn't making
things very happy. When our system was setup by our VAR, they configured us
to have one CallManager (CCM5.1) group, with a publisher at the remote
office, and the subscriber here at the main office.

 

Is it possible to split that out into two groups? What I'm looking at doing
is having both groups set to register to the subscriber here at the main
office, and in the event of a WAN issue, manually changing priority on one
group to register the phones directly to the publisher. Would that work at
all? How much of an overhaul would it be to split one group into two? Would
it even work, would changing the registration priority cause the phones to
automatically re-register?

 

Thanks.
