[cisco-voip] Call Manager 6 upgrade and IPCC-X

[Scott Voll]

Steve--

This is my issue also.  I also bought it up at CIPTUG this year.
Historically UCCx upgrades have not been the best in the first place.

Responses I got were. put your UCCx on its own cluster. (not an option for
me)

replace hardware / do upgrade along side (no $$$s for that)

Deal with it (my default option)  I told Wade (CM BU) I would like to see
UCCx as +/-1 compatible.  Don't know if we will see it in the near future
but he was open.

So when I upgrade from CM 4.1 to 6.1 I also have to upgrade UCCx 4.0 to 5.0,
Xmedius, Berbee informaCast, Arc Console, School Messenger, etc.  So I feel
your indigestion.

As far as Unity... it should be able to integrate to more then one CM
Cluster

ICT trunk should work fine.  if codecs are anything other then G711 might
need transcoding.

If you have the money for Hardware...... I would do a upgrade of both CM and
UCCx hardware then do the switch during a small window.  may even be able to
use some old hardware to make the UCCx redundant. and setup a small IPT lab
;-)
