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 most important thing to understand:
This is not caused by your VQTech phone system. It is determined by how mobile carriers evaluate your calling behavior and number reputation.

What’s Actually Causing the Problem? #

WWireless carriers like Verizon, T-Mobile, and AT&T rely on third-party analytics companies (such as Hiya, TNS, and First Orion) to decide whether a call should be labeled as spam.

These systems use machine learning and large-scale call data to analyze patterns over time—not just individual calls.

Your number may be flagged if it shows patterns such as:

• High call volume in a short period of time
• Sudden spikes or inconsistent calling activity
• Low answer rates or short call durations
• Repeated calls to the same numbers
• Calling customers who are not expecting your call
• Calls placed outside normal business hours
• Customers marking your calls as spam
• Missing, inconsistent, or unregistered caller ID

Even legitimate businesses can be flagged if their calling patterns resemble robocall or telemarketing behavior.

Why New Numbers Get Flagged More Easily #

New phone numbers are especially likely to be labeled as spam.

This is because they do not yet have an established call history or reputation. Carriers treat new numbers cautiously since spam callers frequently rotate numbers.

If a new number immediately begins making high volumes of outbound calls, it significantly increases the chance of being flagged.

It’s Not a VoIP Software Issue #

VQTech phone systems fully support modern security standards like STIR/SHAKEN, which verifies that your caller ID is legitimate and not being spoofed.

However, STIR/SHAKEN only confirms identity—it does not control how carriers label your calls.

Carriers still evaluate:

• Your calling behavior
• Customer engagement (answer vs ignore)
• Spam reports and complaints
• Overall number reputation

Because of this, even fully verified numbers can still appear as “Spam Likely.”

Why Answer Rate Matters #

Carrier analytics pay close attention to how recipients interact with your calls.

If your calls are frequently:

• Ignored
• Declined
• Hung up on quickly

This signals that your calls may be unwanted. Over time, this lowers your number’s reputation and increases the likelihood of being flagged.

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:

FreeCallerRegistry.com

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
• Ensure your business name matches your caller ID (CNAM)
• Allow 2–5 business days for process

Additional Best Practices to Avoid Spam Labeling #

To improve your number reputation and reduce the risk of being flagged:

• Maintain consistent call volume (avoid sudden spikes)
• Gradually increase usage on new numbers (warm-up period)
• Call during normal business hours
• Clearly identify your business at the start of each call
• Use separate numbers for different purposes (sales, support, billing)
• Keep accurate customer consent and opt-in records
• Provide a clear way for customers to opt out of calls
• Avoid aggressive or repeated dialing patterns

These practices help carriers recognize your calls as legitimate and expected.

How to Fix a Number Already Marked as Spam #

If your number is currently labeled as spam:

• Register your number through FreeCallerRegistry.com
• Identify which carrier is flagging your calls
• Submit a review request if available
• Adjust your calling patterns immediately
• Monitor answer rates and engagement

There is no instant fix. Spam labels are based on ongoing behavior, and removal can take several days or longer depending on the carrier.

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:

Visit: https://voicespamfeedback.com/vsf/

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
• Consider using multiple numbers for different teams or functions

These practices can help keep your business calls reaching customers reliably.

Other Helpful Tips: There Is No Single Fix #

There is no one-step solution to eliminate spam labeling completely.

• Successful long-term results require:
• Consistent calling behavior
• Verified and registered caller identity
• Strong number reputation over time
