How many IP phones will our setup support

Answered Question
Jun 25th, 2009

I was curious what the max number of phones we can operate with Call Manager 6.1.2.1000-13 and Unity 5.0 Build 5.0(1)

on Cisco MCS 7800 Series servers.

Would it handle at least 5000 phones?

I have this problem too.

Hi Ryan,

Just thought that I would add a note to the great tips from Java and Kelvin (+5 points each guys :)

I just looked this up the other day;

Cisco MCS 7845 (All supported models)

Maximum Users per Server 7500

Cisco MCS 7835 (All supported models)

Maximum Users per Server 2500

Cisco MCS 7825 (All supported models)

Maximum Users per Server 1000

Cisco MCS 7815 or MCS 7816 (All supported models)3

Maximum Users per Server 300

From this excellent SRND 6.x Guide;

Hope this helps!

You're not proving the information needed to tell you, just saying you got MCS is not enough.

Read these links and you'll get your answer.
