Block certain incoming numbers?

I know how frustrating it can be to get a lot of unwanted calls. I apologize for the delay in our response. You can always block unwanted numbers from reaching you buy using our selective call rejection feature. More information on this service and how to access it can be found through this link https://comca.st/2SyUWW1

When you don't want to be interrupted by certain callers, Selective Call Rejection allows you to create a list of up to 12 numbers that will receive an announcement indicating you are not presently accepting calls. 

Add Phone Numbers to Selective Call Rejection:

1. Log in to Comcast Business My Account.
2. Under the Services tab, select your voice service.
3. On the right-hand side, select Feature Settings and then select Privacy.
4. Scroll down to Selective Call Rejection and select Add New Rule.
5. Add a Rule Name. To add specific phone numbers, select Selected phone numbers and add the phone numbers you would like to be a part of the rule.
6. Select Add Rule.

Just block? Without a stupid announcement, please? I need to block block certain callers.
