Maximum number of route-patterns of CallManager cluster


Just wondering if there is a guideline for the maximum number of route-patterns of one callManager cluster from the performance perstective of view.

CCM 4.1(3), Two MCS7825 servers for one cluster.




Re: Maximum number of route-patterns of CallManager cluster

It depends on the load that each server supports, and is not an information for only the Route Patterns, you need to sum all the devices:

Maximum Number of Devices per Server Platform:

- MCS-7845 --> 7500

- MCS-7835 --> 2500

- MCS-7825 --> 1000

- MCS-7815 -> 300

Device wights determine the maximum number of physical devices that can be registered to a

CallManager subscriber. Some IP Pone models support multiple lines (directory numbers or

line appearances). Many IPT deployments have directory numbers that are shared across

multiple IP Phones and a large number of dial plan entries that include route patterns;

translation patterns require an extra amout of resources (CPU,memory) on the CallManager.

Dial plan weights provide the limit on the number os fuch dial plan entries configures in

a CallManager subscriber. Dial plan weight calculations provice guidelines to size the

cluster .

Base Dial Plan Weights:

IP phone device (excluding lne appearances) --> 5

Unique line appearance --> 5

Shared line appearance --> 4

Route Pattern --> 2

Translation Pattern --> 1

Re: Maximum number of route-patterns of CallManager cluster

Thanks for your information. But I am not sure how to calculate those route-patterns against to the number of MCS7825 supported 1000 devices.

For example, if I have 2500 route-patterns, with 300 IP Phones, each has two lines are configured. How many of devices will be calculated?
