Call Blocking and Spam Protection
AI Phone System · Answer and route
Call blocking stops unwanted callers before your phones ever ring. Voxtell blocks specific numbers and number patterns at the system level, so robocalls and repeat spam callers never reach your staff. The same protection covers spam text messages too.
What it does
Call blocking and spam protection lets you shut out unwanted callers at the system level. You can block a specific number, or a whole pattern of numbers, so robocalls and repeat spam callers never ring a single phone in your business. The protection extends to text messages as well, keeping junk out of your business inbox.
Every blocked call is time your team gets back. Front desk staff stop picking up recorded pitches. Lines stay open for customers who actually want to reach you. And because blocking happens at the system level, one rule protects every user, desk phone, and mobile app on your account at once.
Fewer junk calls means faster answers for the calls that count. Voxtell customers have seen 25% fewer abandoned calls and a 21% faster speed to answer after switching.
How it works in Voxtell
Setup is white glove. Tell our team which numbers or patterns are hitting your lines and we configure the blocks with you during onboarding. There is nothing to build or figure out on your own: our in-house support team in Orlando handles it with you, and they keep handling it whenever a new spammer shows up.
Blocks apply at the system level, so they cover your whole account: every user, every desk phone, every mobile and web app. Legitimate calls keep flowing exactly the way you designed, through your auto attendant, your call queues, or the AI Receptionist that comes included with your plan.
Spam texts get the same treatment. SMS blocking stops junk messages before they clutter your inbox, so the texts your team sees are the ones from real customers.
How businesses use it
Realty
A busy brokerage runs on inbound calls, and spam competes directly with buyers and sellers for an agent's attention. Blocking robocall patterns at the system level keeps every agent's line clear. When a real lead calls, someone picks up.
Restaurants
During a dinner rush, a phone line taking takeout orders cannot afford a robocall. Blocking repeat spam callers keeps the line open for hungry customers. Staff stop losing seconds they do not have.
Pet Grooming Retail
Front counter staff at a grooming shop juggle walk-ins, appointments, and the phone at the same time. Spam calls interrupt all three. With blocking in place, the phone only rings for real pet owners.
Logistics
A dispatch office fields drivers, carriers, and customers all day, sometimes across many locations. One system-level block covers every location at once. Nobody has to block the same robocaller at each site separately.
RV Resorts
A resort front desk takes booking calls year round, and a guest who hits a busy line may just call the next resort. Blocking spam keeps the desk phone free for reservations. Guests get through the first time.
County Health
Residents calling a county health office need to get through, and every spam call in the queue slows them down. System-level blocking keeps queues moving. Staff spend their time on residents, not robocalls.
Best practices
- Give our team a list of known spam numbers during onboarding so your blocks are live from day one.
- Block patterns rather than single numbers when spam keeps arriving from a range of similar numbers.
- Pick one person to collect spam reports from your staff, then send the list to Voxtell support to block in one pass.
- Have our team set up SMS blocking too, since spammers who cannot get through by voice often switch to texting.
- Review your blocked list with our support team every few months and clear out entries that no longer matter.
- Keep blocking for confirmed spam, and let your auto attendant or the AI Receptionist handle callers you are not sure about.
