Why Are My Calls Showing Up as SPAM? #
If your business number is showing up as “SPAM Likely” or “Potential Spam” when calling customers, you’re not alone. This issue is increasingly common across industries like healthcare, finance, customer support, and more.
The important thing to know: this is not caused by your VQTech phone system. It’s about how mobile carriers flag calls based on usage patterns.
What’s Actually Causing the Problem? #
Wireless carriers like Verizon, T-Mobile, and AT&T rely on third-party analytics companies (like Hiya, TNS, and First Orion) to flag suspicious or unwanted calls. These companies monitor how numbers behave over time. Calls may be flagged based on:
- High call volume in short periods
- Calling people who weren’t expecting your call
- Customers marking calls as spam
- Incomplete or unregistered caller ID info
This means even legitimate, well-meaning businesses can get caught in the filter just for having common calling patterns.
It’s Not a VoIP Software Issue #
VQTech phone systems fully support modern security standards like STIR/SHAKEN, which helps verify that your Caller ID is not being spoofed. But even with this technology in place, your number can still be marked as SPAM if it’s not registered or if your usage matches spam-like patterns.
How to Prevent or Remove SPAM Labels #
The best way to fix or prevent this issue is to register your phone number with the major spam analytics providers through one portal:
This free service submits your number to:
- TNS (used by Verizon)
- Hiya (used by AT&T)
- First Orion (used by T-Mobile)
Tips for successful registration:
- Use the 11-digit format (e.g., 1-800-123-4567)
- Register each business number separately
- Check your email and complete any required verifications
- Allow 2–5 business days for process
Important Notice for Calls to Verizon Users #
If you are making calls to Verizon numbers, Verizon may require you to register or provide feedback to ensure your calls are not blocked or marked as spam. To comply with Verizon’s requirements and improve call deliverability:

Follow the instructions on the site to submit the necessary information. This will help ensure your calls reach Verizon users without interruption.
For Medical, Financial, and High-Volume Callers #
Businesses in sensitive or high-volume fields (like medical practices, billing departments, or sales teams) may need to:
- Re-register periodically as carrier spam filters update frequently
- Warm up new numbers slowly before high call volume
- Rotate numbers if needed, and avoid blasting from a single line
These practices can help keep your business calls reaching customers reliably.
Other Helpful Tips #
- Double-check that your Caller ID is accurate and consistent
- Avoid automated call patterns that could look like robocalls
- Don’t share one number across too many agents or departments
- If your number keeps getting flagged, it may be worth starting fresh with a new number
