CUCM 7.0 - Design Question

Answered Question
Sep 8th, 2009

I've a quick question for the design of our CUCM 7.0 cluster. We are going to be clustering over the WAN, using 3 servers - new 7825-I3 MCS - with at present about 350 phones.


Here's my design plan can anyone tell me if this looks good/bad/ugly? :)


Server 1: Publisher/TFTP (not providing call services)

Server 2: Subscriber, Primary CallManager

Server 3: Subscriber, Secondary CallManager


Thanks!

Hi Rob,


Looks pretty good :) The only change i would make is this;


175 IP Phones


Server 1: Publisher/TFTP (not providing call services)

Server 2: Subscriber, Primary CallManager

Server 3: Subscriber, Secondary CallManager



175 IP Phones


Server 1: Publisher/TFTP (not providing call services)

Server 3: Subscriber, Primary CallManager

Server 2: Subscriber, Secondary CallManager


This way the Call Processing load would be spread over Server 2 & 3.


Cheers!

Rob
