The Cisco best practice is: to point a route pattern to a route list to point a route list to one or more route groups to point a route group to one or more devices. To learn more about route lists before starting with the config, I suggest you check this good theoretical introduction . Implementation of the Example Setup I configured for HQ site: a CUCM route list named CorpHQ-RL a route group named CorpHQ-RG  that points to the HQ H.323 gateway. I configured the same for Branch1: a CUCM route list named Branch1-RL a route group named Branch1 – RG  that points to the Branch1 H.323 gateway. Let us start with HQ site: In my home lab, I pointed all route patterns to the same route list. For example, pattern 911: Now the branch site: The same pattern 911 in the Branch1 office ...

In this blog post I am going to describe the concept of Class of Service with an example based on the configuration of Calling Search Spaces (CSS).

For example, for HQ phones, line 7175438411 is a local PSTN line, while for Branch1 phones the same line is considered long distance. We define the following partitions: CorpHQ-internal_PT CorpHQ-Local_PT CorpHQ-LD_PT CorpHQ-International_PT CorpHQ-EMS_PT And we define Calling Search Spaces: CorpHQ-Internal_CSS CorpHQ-local_CSS CorpHQ-national_CSS CorpHQ-international_CSS In the following...
