Blocking Inbound Call by Caller ID

1. Brekeke Product Name and Version:
SIP Server 3.13.0.0
2. Java version:
11.0.15
3. OS type and the version:
Windows Server 2016
4. UA (phone), gateway or other hardware/software involved:
Mostly 3CX
5. Your problem:
I would like to block incoming calls from a specific Caller ID. I've tried the following, but it did not work. What am I doing wrong?

Matching:
$Request = ^Invite
From = sip:12223334444

Deploy:
$action = 603

The '12223334444' represents the Caller ID number that I'm trying to block.

"^Invite" should be "^INVITE" so the Matching pattern will be like this

Matching Patterns:
$request = ^INVITE
From = sip:12223334444

I did use ^INVITE (just didn't capitalize it here).

I tried it in the Preliminary Rules (at the top) and in the regular Dial Plan rules (at the top) and neither worked.

Found my problem. The Matching and Deployment entries did work. Hand another problem.
