What is the maximum number of route patterns configurable on the Call Manager (version 4.23)? How significantly will this large number of route patterns affect the performance of the Call Manager? We have several route patterns (over 150), but I am reviewing the option of using Route Filters in order to minimize this number. Let me know the concerns.

There is no software limitation about the maximum number of route patterns and

translation patterns. However, the limit is really based on how much memory the

server has and hard drive.

You need to use the CallManager Capacity Tool to determine the number.

In 4.1.3 I remember that with 7500 Phones, 2500 CTI Lines, 25,000 Route Patterns and 25,000 Translation Patterns are supported by one MCS 7845-H1/H2 Server.

Thank You

I have one Call Manager cluster using one CM4.2-K9-X306M publisher and one subscriber. I know it supports a maximum of 500 Phones however I am not sure about the number of route patterns and translations. Can you assist?
