CUCM Initial Configuration - Checking Service Parameters

After installing CUCM, some initial configuration steps need to be done before deploying endpoints, they are as follows:

1. Configure network settings
2. Verify network and feature services
3. Configure Enterprise Paraeters
4. Configure Service Parameters

Point 4. Checking Service Parameters
Service parameters are used to define settings for a specific service that was enabled by activating Feature Services. These default parameter values should be verified and or modified before registering endpoints.

Some of the most import service parameters are:

• T302 timer - Reducing this default value reduces the interdigit timer for variable length number, basically shorter post-dial delay. (See how this can be done on CUCME IOS).
  
• CDR and CMR - Used for call reporting, accounting and billing.
  
• CUCM Extension Mobility maximum login time - Logs user out of extension mobility regardless of idle timer on device.

These parameter values can be found if you goto System > Service Parameters
