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.
