Call Screening & Blocked Callers

Stop spam and scam calls automatically, and block specific numbers from reaching your team.

Overview

Both tools are in CRM → Admin → Phone Settings → Screen, on two tabs at the top of the panel, and require an organization admin:

Inbound Call Screening — checks callers against spam and scam databases, per number.
Blocked Callers — your own list of numbers that can't call you.

On the Inbound Call Screening tab, find the number (the table shows who it's Assigned To).
Tick Screening to turn it on.
Choose the Action. It saves immediately.

Screening only works on calls from the US and Canada, and only numbers bought through VINSI are listed.

Action	What happens to a suspected spam call
Reject (default)	The caller hears "call cannot be completed" and your phones never ring.
Flag only	The call rings through as usual, marked as possible spam.

Start with Flag only on your main line if you're worried about blocking real customers.

On the Blocked Callers tab, enter the Phone number to block (at least 10 digits).
Choose the scope: Org-wide (all numbers) or one of your numbers.
Optionally add a Reason so teammates know why.
Click Block.

Blocked callers hear "call cannot be completed". Numbers match on their last 10 digits, so 5551234567 and +1 (555) 123-4567 are the same entry.

Org-wide — the caller can't reach any of your numbers.
A specific number — blocked only when calling that number (e.g. a harasser of your support line who is still a sales prospect).

Click Unblock next to the entry and confirm. Their future calls ring through again.

Question	Answer
Can I block callers with no caller ID?	No — calls without a number can't be matched against the list.
Does blocking affect outbound calls?	No, you can still call a blocked number.
Can I block the same number twice?	No — you'll see "already blocked" for the same scope.
Does screening work for international callers?	Spam screening only checks US and Canadian calls; the block list works for any number.
