How to: Avaya IP Office: Block Specific Incoming Caller IDs Found

This How-To covers blocking a specific number from being able to get through your Incoming Call Routes on an Avaya IP Office.

This guide is based around release 9.1, but it also covers earlier releases.

4 Steps total

Step 1: Create A New Incoming Call Route
Go to Incoming Call Routes, right click and select New to create a new Incoming Call Route. Modify the Standard tab as follows:

Line Group ID: Set this to the incoming Line Group ID.
Incoming Number: * (for some earlier versions, you may need to put the Incoming Number in there instead).
Incoming CLI: Set this to the number you want to block calling in.

Press OK to save the changes. We will come back to add the Destination in Step 3.

Step 2: Create A New Short Code
Go to Short Codes, right click and select New to create a new Short Code. Modify the Short Code as follows:

Code: Set this to an unused Short Code (for example *810)
Feature: Barred

Press OK to save the changes.

Step 3: Modify The Incoming Call Route

Go back to the Incoming Call Route you created in Step 1 and click on the Destinations tab. Set the Destination to the Short Code you created in Step 2 on the Default Value Time Profile entry.

Press OK to save the changes.

If you wish to block the number at certain times of day, you can use Time Profiles to accomplish this by routing to the Barred Short Code at specific times and to the desired User/Hunt Group at other times.

Step 4: Save The Configuration
All that is left to do now is to save the changes you have made to the live system. To do this, press File -> Save Configuration.

The changes made should only require a Merge, not a Reboot.

This should now stop the callers from being able to get through the Incoming Call Route. If you wish to block callers that withhold their Caller ID, you can use the following in the Incoming CLI field of the Incoming Call Route:


Using the exclamation mark matches all calls where the Caller ID was withheld.
