Call Firewall
Stop the calls that cost you time.
Block nuisance callers before your phone rings, and let the people who matter straight through.
Rules that work the way you think.
Set them once. Every decision is logged so you can see what was stopped and why.
Block exact numbers
Block a number for a day, a week or for good.
Block withheld callers
Stop calls that hide their number, or send them to screening instead.
Block prefixes and countries
Block by number prefix or the country shown on the caller ID.
Catch repeat callers
Set a limit, such as three calls in an hour, and block anyone who goes over.
Protect your contacts
An allowlist overrides every other rule, so customers never get caught.
Screen the unsure ones
Hand uncertain calls to the receptionist and only ring you if they pass.
An honest limit
Country blocking uses the caller ID presented with the call. Callers can disguise it, so it reduces nuisance calls but cannot guarantee where a call really comes from.
Get your quiet back.
Add a Firewall rule in a few clicks and see it work on the next call.
