Call Manager/CUCM co exist advice please.

Unanswered Question
Mar 21st, 2010

Hi all

Looking for a little advice if possible.

We have a Callmanager Pub Sub config (4.1(3)  at the moment with IPCC 4.0(5),

we have new servers coming in, new install CUCM 7, but not upgrading IPCC for another 8 months.

We have quite a complex dial-plan, I am after advice really how best to tackle this as we will have

to co-exist both callmanager versions and they must be connected (Inter Clus Trunk)

How would you suggest I replicate the dial plan and CSS,PARTITION etc.  to CUCM 7, also 4.1 will have to carry on serving IPCC.

All new phoned#s added will have to go onto CUCM 7.

The gateways I presume will have to remain registered with CM 4.1, to handle offnet calls ?

Any advice or docs would be appreciated.

I have this problem too.
