CoreReach blocks unwanted calls in two ways: automatic filters that are always on, and a custom list of phone numbers you maintain yourself. Both live under Activate → Call Blocking.
Automatic blocking
Two filters are enabled by default and can't be turned off:
Block Spam & Robocalls — calls flagged as spam or robocalls are blocked before they reach your agent.
Block Toll-Free Calls — incoming calls from toll-free numbers (1-800, 1-888, etc.) are blocked automatically.
Both appear at the top of the Call Blocking page as read-only Automatically Blocked toggles.
Blocking specific numbers
Below the automatic filters, you can block up to 50 specific phone numbers. This is useful for known nuisance callers, competitors, or numbers you've decided to ignore.
Each entry has:
Phone number — a US 10-digit number, validated when you tab out. Duplicates are flagged so you don't accidentally block the same number twice.
Note (optional) — context for yourself (e.g., "Persistent telemarketer," "Ex-employee — do not call back").
To add one, click Add Number To Block (or Add Another Number if your list isn't empty) and fill in the fields. The Add button disables once you've hit 50. Numbers are edited in place and saved with the Save button at the bottom. Deletion is per-row via the delete button — there's no confirmation step, so be sure before you click.
There's no bulk import, reordering, scheduled blocking, allow list, or "block all unknown numbers" option — only the targeted list above.
What happens when a call is blocked
A blocked call:
Doesn't reach your agent. Your agent never picks up.
Doesn't use any of your minutes. Blocked calls aren't billable.
Is recorded in your call history with the Blocked outcome and a label showing why it was blocked: Specified number, Spam call, or Toll-free number.
By default, blocked calls are filtered out of the Calls list view to keep your call history focused on real interactions with your agent. To review them, change the outcome filter to include Blocked.
