hi all, before all i'd like to thank all of you guys for your help and information provided recently SO...
I got stuck in one thing What's the main difference between Publisher the one who held the Data Base and where changes occurs and the Primary CallManager were ip Phones looks for when they are connected to the LAN so thanks for your reponse
Hope all is well! In the basic design of a CCM cluster there may be 1 - Publisher and 2 - Subscriber servers. The recommendation is that IP Phones are not registered on the Publisher. When you define your Calmanager Groups you might setup Group 1 as;
And Group 2 as;
In Group 1 the Pimary Callmanager is Pub-1 and in Group 2 the Primary Callmanager is Pub-2. This is in reference to the phones registered with each Callmanager Group (with the highest one listed being the Primary or "First choice") and is not related to the Publisher and its funtionality in any way :) The wording can be a tad confusing at times.
Hope this helps! (and makes some sense)
