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
