# Call Blocking
> Call blocking allows administrators to block incoming calls from specific phone numbers on an account.
## Call blocking allows administrators to block incoming calls from specific phone numbers on an account. This guide provides step-by-step instructions for managing call blocking in the Omnia Admin Portal.
This document applies to the following user roles within Omnia:
Account Administrator
Partner Administrator
Call blocking works one number at a time — calls from exactly the numbers on your blocked list are rejected, and that's the only filter the system applies. There is no automated, network-wide spam filter you can turn on. Spam callers commonly rotate caller IDs (a tactic called *neighbor spoofing*) using a large pool of random numbers, so a number you block today may not be reused tomorrow. Block the specific numbers you can identify, but expect to keep adding new ones as patterns shift.
