If your outbound calls are showing up as Spam Likely, Scam Likely, or Fraud Risk, the issue isn’t with your Unitel service or your phone number. Mobile carriers like AT&T, Verizon, T-Mobile, and analytics partners (Hiya, First Orion, TNS) use their own independent reputation databases to flag suspicious traffic — and those flags can sometimes be wrong.
Why This Happens
Carriers use algorithms and reputation databases to detect possible spam patterns. Your number may be flagged if your traffic shows signs like:
High call volume in a short time
Low answer rates (many call attempts / few pickups)
Short-duration calls
Repeated calls to the same number
Calling people who frequently mark unknown numbers as spam
No caller ID name registered
Use of auto-dialing tools
Brand-new numbers making large call bursts
Previous activity from another business that owned the number before you
Even small businesses making legitimate calls can sometimes get flagged by mistake.
How to Check if Your Number Is Flagged
You can manually check your phone number against the major reputation databases used by wireless carriers:
1. Free Caller Reputation Lookup Tools

These services allow you to request reclassification if your number is legitimate.
Best Practices to Avoid Being Flagged
Carriers judge your “reputation score” based on traffic patterns. To protect your number:
Keep answer rates healthy (avoid repeated unanswered calls).
Make sure your Caller ID Name (CNAM) is set correctly.
Avoid short-duration calls that look like autodialer traffic.
If you purchased a new number, call lightly for the first week (“warm-up period”).
Do not run political, survey, marketing, or auto-dialed campaigns.
If you’re using business texting, make sure your 10DLC registration is approved — unregistered or high-volume SMS traffic can also impact your call reputation.
Unitel Voice’s Role
Unitel Voice can help by:
Checking your CNAM record
Reviewing call patterns to identify possible triggers
Replacing a number that appears permanently tainted (rare)
However, Unitel Voice cannot override the carriers’ spam databases — only the carriers and their analytics partners can remove flags.
Frequently Asked Questions
“Does registering CNAM fix spam labeling?”
Not always. CNAM helps, but reputation databases are separate from caller ID name databases.
“Can Unitel Voice remove the spam tag for me?”
No carrier allows VoIP providers to remove flags on your behalf. Only you (the business owner) can submit tickets directly.
“How long does it take for a spam label to be removed?”
Usually 24–72 hours, depending on the analytics provider.
“Will changing my number fix the issue?”
Only if the number’s reputation is permanently damaged. In most cases, a review request resolves the problem.
“Why do only some people see Spam Likely?”
Each carrier uses different analytics providers, so one network may flag you while another does not.
“Can my number be flagged again later?”
Yes — if calling patterns trigger the carrier algorithms again. Following best practices helps prevent this.
What to Do Next
If your outbound caller ID is showing as “Spam Likely,” we recommend:
Run your number through the lookup tools above.
Submit correction forms to Hiya, First Orion, and TNS.
Review your calling patterns for any behaviors that could trigger flags.
Contact Unitel Voice Support if you need help analyzing call logs or updating CNAM.
