Picture the least suspicious call imaginable. A customer asks for a quote. You prepare it. You call them back.

Their phone says "Spam Likely."

Your customer requested a callback. Their phone has declined on their behalf.

Those labels come from the customer's carrier or spam apps, not RocketVox. We do not control their filters.

There is no master spam list. Calling patterns and complaints matter; your appointment book does not.

What we do

Whenever you call from one of your RocketVox numbers, we digitally sign the call with STIR/SHAKEN "A" attestation, the highest level of caller-ID authentication. That confirms we know your business and have verified your right to use the number.

It is identification, not a character reference, and it does not guarantee freedom from spam labels.

Free Caller Registry

Free Caller Registry shares your business and number details with three major companies that help carriers identify spam. Registration is free and helps them recognize your business.

It does not guarantee your calls will ring or appear without a warning.

Spam apps

Apps such as RoboKiller and Nomorobo can block calls the carrier lets through. Your call passed security. Unfortunately, there is more security. Registering with one service does not mean every app will let you in.

Smartphone settings

iPhone settings can screen or silence unknown callers; Google's Phone app can filter suspected spam. An unsaved number can be silenced without ever getting a spam label. Sometimes your entire offense is not being in their contacts.

One business. One main number.

Advertising numbers that forward to your business can put one number in the ad and another on your customer's screen when you call back. Your analytics know the connection. Your customer missed that briefing.

Drop the substitute numbers. Publish one main business number, call from it, and receive calls on it. It will not override spam filters, but people can save it and call back.

Best practices

  • Register your main business number and keep business details accurate.
  • Use that number in ads and for incoming and outgoing calls.
  • Tell customers when to expect your call; ask them to save your number.
  • Space follow-ups sensibly and honor requests to stop. A sixth call rarely clears up the misunderstanding.
  • Request review from the carrier or app applying an incorrect label.

The bottom line

You cannot control every spam filter. You can give customers a familiar number and a reason to answer. Their phone may still have trust issues.
