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.
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
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
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?
