Submitting your outbound phone numbers to the Free Caller Registry is the standard method to protect your Caller ID Name (CNAM) from being flagged as SPAM or “Scam Likely.” Paid third-party platforms offer additional monitoring and remediation capabilities beyond basic registration; contact your CyberLynk sales representative to learn more about these options.
Free Caller Registry Submission #
The Free Caller Registry allows legitimate businesses to register phone numbers directly with major U.S. wireless carriers and analytics providers (Hiya, First Orion, and Transaction Network Services) at no cost. We recommend submitting all primary business lines and publicly distributed Direct Inward Dialing (DID) numbers every six months to maintain clean caller ID status.
What to Expect During Registration #
When submitting numbers to the registry, be prepared to provide the following information:
- Business Information: Legal business name, corporate address, main phone number, and official website URL.
- Contact Details: Name, email address, and phone number of a authorized contact person within your company.
- Number Inventory: A list of outbound phone numbers (DIDs) you want to register and protect.
- Call Use Case: A brief explanation of the nature of your outbound calls (e.g., customer service, appointment reminders, sales follow-ups).
Once submitted, analytics algorithms and carriers review the details to verify legitimacy. Approval and vetting usually take a few business days to complete.

How to Avoid Being Flagged as Spam #
Do:
- Register your business numbers with Free Caller Registry (as noted above) and keep the registration current if your business name, address, or authorized contact changes.
- Use consistent Caller ID / CNAM across all your numbers so your business name displays correctly and doesn’t look spoofed.
- Warm up new numbers gradually. Start with low call volumes and increase over days or weeks rather than blasting high volumes from a brand-new number on day one.
- Maintain a steady, predictable calling pattern. Sudden spikes in outbound volume are one of the biggest triggers for spam analytics.
- Keep your outbound answer rate healthy. If most of your calls go unanswered or get sent straight to voicemail, that’s a signal carriers use to flag numbers.
- Space out calls to the same number. Repeated, rapid-fire calls to a person who hasn’t answered look like harassment or robocalling behavior.
- Use dedicated numbers for outbound campaigns (sales, appointment reminders, collections-adjacent calls, etc.) separate from your main inbound business line, so a flagged campaign number doesn’t take down your primary line’s reputation.
- Keep your information accurate and up to date with CyberLynk (business name, contact person, physical address, EIN/TIN) since carriers cross-reference this data when scoring your traffic.
Don’t:
- Don’t use auto-dialers, predictive dialers, or robocalling software on TalkAnywhere lines. This is a violation of the our Use Policies and is one of the fastest ways to get flagged and suspended.
- Don’t call from a number immediately after porting it in without checking its prior reputation; a number’s history follows it.
- Don’t make cold outbound calls at very high volume or velocity (many calls per minute from one line), which mimics telemarketing/robocall patterns.
- Don’t ignore high complaint or block rates. If recipients are consistently blocking or reporting your number, continuing to call from it will accelerate a bad reputation.
- Don’t use the service to originate calls for telemarketing, lead generation, or call center operations unless you’ve arranged for the appropriate service tier.
- Don’t share or resell your number/service to third parties. Reputation is tied to usage patterns, and mixed traffic from unrelated parties makes flags more likely and harder to resolve.
- Don’t let a number sit unused for long periods and then suddenly ramp up heavy outbound calling; dormant-then-spiking usage is a common spam signature.
