Customers ring through. Every incoming call is checked against a national spam database. If you like, GBPN can also check caller ID verification from the carrier, which catches spoofed numbers. Real callers go straight through to your greeting and your phone, the same as always. Each call shows what happened, step by step, so you can see it was checked.

You decide what happens. ### Send spam where you want Flagged calls go where you choose instead of ringing you: hang up, or send them to voicemail. GBPN can also mark them done or block them for you automatically. ### Still on the record Every flagged call is saved and labeled "Flagged as spam". If a real customer ever lands there, you can see who called and call them back. ### Block anyone in two taps Block a caller from the app or your computer and pick a reason: spammer, scammer, unwanted contact, or abusive. Their calls never ring through, and their texts notify no one. Unblock any time. Spam screening isn’t switched on for every account. Ask, and we turn it on for you, free. ## Spam call questions How does GBPN know a call is spam? The spam filter checks every caller against a national spam database before your phone rings. You can also turn on a caller ID verification check, which catches calls the carrier could not verify. What happens to a call that is flagged as spam? It goes where you choose instead of ringing you. Most people hang up on it or send it to voicemail. The call is still saved in GBPN and marked "Flagged as spam", so you can always check it. Is spam screening turned on automatically? Not on every account. Ask, and we turn it on for you, free. It takes a real person a few minutes on the phone with you. What happens when I block someone? Their calls never ring through, and their texts do not notify anyone on your team. You can add a reason, such as spammer or scammer, and unblock them any time. Will a real customer ever get blocked by mistake? Flagged calls are never deleted. Each one stays in GBPN with the label "Flagged as spam", so you can see who called and call them back if it was a real customer. ## More of what’s included - [Business calling Know it’s business before you answer. →](https://gbpn.com/business-calling) - [Greetings, hours, and menus Calls go where you want, when you want. →](https://gbpn.com/call-routing) - [Voicemail Read every message in your email. →](https://gbpn.com/voicemail) - [Missed-call text back Callers get a text when you can’t pick up. →](https://gbpn.com/missed-call-text-back) - [Business texting Text and send photos from your business number. →](https://gbpn.com/business-texting) - [Business contacts Every customer and their whole history. →](https://gbpn.com/contacts) - [Never forget a follow-up Always know who you owe a call or text. →](https://gbpn.com/follow-ups) - [How the inbox works Needs, Waiting, Snoozed, and Done. →](https://gbpn.com/workflow) - [Caller ID and trust Look like a real business when you call. →](https://gbpn.com/caller-id) - [How GBPN uses AI Less busywork, and you stay in charge. →](https://gbpn.com/ai) - [AI call summaries Know what every call was about. →](https://gbpn.com/ai-call-summaries) - [Work as a team Add teammates and ring the right person. →](https://gbpn.com/team) - [Call reports Missed calls, busy hours, and who answered. →](https://gbpn.com/reports) - [iPhone and Android app Free with every line.
