If you’re short on time, start with Step 1: Register your numbers.
Start here
If your customers see “Spam Likely” or “Scam Likely” when you call, you’re not alone. Even legitimate businesses can be mislabeled—and that can reduce answer rates and slow down your business.
This article explains why it happens, what triggers it, and the best steps to reduce it.
Why this is happening more now
Phone carriers and call-protection partners use analytics to protect consumers from unwanted calls. Over the last few years, these systems have become more aggressive, and normal business calling behaviors can sometimes look “spam-like” to automated filters.
Important: Call labeling is typically determined by the receiving carrier and its analytics partners, not OneCloud. While we can help you troubleshoot and improve outcomes, we can’t directly control how another carrier displays labels.
What triggers “Spam Likely”
Common patterns that can increase the chance of labeling include:
•High-volume bursts (many calls in a short time from one number)
•Very short calls (repeated 3–10 second attempts)
•One-way calling (lots of outbound calls with limited two-way conversations)
•Rapid repeat attempts to the same person/number
•Calling people who aren’t expecting you (cold outreach increases reports)
•Missing or inconsistent Caller ID Name (CNAM)
•Recipients tapping “Report Spam”
•Ignoring opt-outs / Do Not Call best practices (if applicable)
Step 1 (Most important): Register your outbound numbers (Free)
Registering your numbers helps call-protection systems recognize your business identity. This is the best first step to reduce the likelihood of being mislabeled.
What to do:
•Register the numbers you use to call customers (main number and/or direct dials)
•Use consistent business information
•Keep it updated if your business name or contact info changes
Note: Registration helps, but does not guarantee immediate removal of labels across every carrier/app.
Step 2: Keep your calling behavior “human”
Carriers often flag patterns that resemble automated dialing. These adjustments typically help:
•Keep volume consistent (avoid sudden bursts from one number)
•Avoid burst dialing from a single direct dial
•Encourage two-way conversations when possible
•Leave a voicemail when unanswered (reduces “silent/abandoned call” patterns)
•Clean your lists (wrong numbers + repeat failures increase risk)
•Honor opt-outs / Do Not Call best practices
•Avoid spam-like tactics (examples: rapid redial loops, calling large lists repeatedly, or campaigns that generate many short/abandoned calls)
Step 3: Make sure your Caller ID is complete and consistent (CNAM)
Caller ID Name (CNAM) helps recipients recognize your business. Missing or incorrect CNAM can increase distrust and spam reports.
•OneCloud supports CNAM registration.
•CNAM is typically set up on the main number; additional numbers may have an added cost.
•Customers may choose to present a main number or direct dials, either is acceptable. The key is consistency and registration.
Optional: Monitoring tools (not required)
If outbound calling is critical (sales teams, service scheduling, collections, etc.), monitoring can help you catch issues early across carriers and blocking apps.
An example tool is CallerIDReputation (optional third-party):
If you’re already being flagged: quick recovery checklist
1.Register your numbers (Free Caller Registry)
2.Reduce burst calling and very short attempts for several days
3.Confirm CNAM is present and accurate
4.Rotate/replace numbers if needed (customer-controlled)
5.Submit disputes/remediation with the relevant labeling/analytics providers (customer-owned process)
How OneCloud can help
We’re here to help you troubleshoot and improve outcomes.
OneCloud can assist with:
•Helping you understand your call history to identify patterns
•Requesting CNAM updates
•Confirming your outbound calling configuration and recommending best practices
•Guidance on number rotation/replacement (customer-controlled)
Service note: If you need OneCloud to take a hands-on role beyond standard guidance (ongoing repeated pattern analysis, continual number rotations, or OneCloud-led dispute work), professional services may apply.
If you have questions for individual companies or believe your calls are being impacted by a specific company, you may contact each of the companies directly here:
