How to Configuring After-Hours Call Blocking in Call Manager Express ?

In the traditional telephony realm, there have been many recorded incidents of unauthorized phone calls being placed after-hours, when most, if not all, staff has left for the evening. To prevent this, you can implement after-hours call blocking on CME.

After-hours call blocking allows you to define ranges of times specified as after-hours intervals. You can then list number patterns that are disallowed during those intervals. If a user places a call during the after-hours time range that matches one of the defined patterns, CME will play a reorder tone and disconnect the call. Of course, there are exceptions to every rule. You may want to have some phones completely exempt from the policy, or give users a "back door" around the restrictions if they are working late and need to make business-related calls that CME would typically restrict. The after-hours call blocking configuration on CME provides for both of these scenarios. You have the option to completely exempt certain IP phones from the after hours restrictions or to provide users with a PIN they can enter into the IP phone. If they enter the PIN correctly, CME exempts the IP phone from the after-hours policy for a configurable amount of time

After-hours call blocking has three major steps of configuration:

 Step 1. Define days and/or hours of the day that your company considers off-hours.

Step 2. Specify patterns that you would like to block during the times specified in Step 1.

Step 3. Create exemptions to the policy, if needed.
