In today’s hyperconnected world, cold calling remains a cornerstone of B2B lead generation—but nothing derails outreach faster than seeing “Spam Likely” flash on your prospect’s screen. With stricter carrier algorithms and heightened consumer skepticism in 2025, businesses must adopt proactive strategies to protect their caller ID reputation while maintaining ethical outreach standards. Below are actionable steps backed by industry research and real-world insights from SalesHive’s decade-long expertise in scalable cold calling solutions.
1️⃣ Register Your Numbers with Carriers & Analytics Providers
Phone carriers like AT&T, Verizon, T-Mobile rely heavily on third-party analytics engines (e.g., Hiya or First Orion) to flag suspicious numbers globally registered via platforms like Free Caller Registry. To avoid mislabeling:
- Submit your business name, phone numbers, tax ID, website URL, email address, etc., directly through these registries.
- Work closely with your VoIP provider or IT teamto ensure consistent updates whenever you add new numbers.
SalesHive simplifies this process by integrating carrier registration into its AI-powered sales platform, automating compliance checksand reducing manual oversight. Clients benefit from pre-vetted U.S.-based phone pools optimized for minimal spam risk.
2️⃣ Implement STIR/SHAKEN Protocols
STIR (Secure Telephone Identity Revisited) / SHAKEN (Signature-based Handling of Asserted Information Using Tokens) frameworks authenticate caller IDs over IP networks, combating spoofing attemptsand signaling legitimacy. Key steps include:
- Partnering with VoIP providers certified for STIR/SHAKEN compliance.
- Obtaining certificates of authenticityfor every outgoing number.
- Regularly auditing call traffic patternsto detect anomalies early.
Platforms like SalesHive’s proprietary system embed these protocols into workflows, ensuring seamless authentication even during high-volume campaigns.
3️⃣ Optimize Call Volume & Distribution Strategies
Sudden spikes in outbound calls trigger red flags. Research suggests limiting daily calls per number below 501:
- Distribute activity across multiple local DID(Direct Inward Dialing) numbers matching prospects’ area codes. For instance:a Denver-based SaaS company could use separate Colorado-, Texas-, and California-specific lines.
- Schedule follow-ups strategically—avoid back-to-back dials within short windows unless responses demand urgency.
SalesHive addresses this through tiered service packages (Starter vs Crush)that allocate call volumes based on team size, geography,and campaign complexity.
4️⃣ Maintain Accurate & Consistent Caller ID Info
Carriers cross-reference incoming calls against public databases like Yelp or BBB listings:
- Ensure your business name matches exactly across directories (e.g., “SalesHive LLC” vs “Sales Hive Inc.”)!
- Update CNAM(Caller Name) records quarterly via your telecom provider. Mislabeled IDs erode trust instantly.
Pro tip:Test inbound/outbound displays monthly using secondary devices.
5️⃣ Monitor & Repair Number Reputations Proactively
Even compliant campaigns face occasional flags due to recipient reports or algorithmic quirks:
- Use tools like Nomorobo or carrier dashboardsto track spam complaints.
- If flagged,submit correction requests promptly through Hiya, TNS, etc. Include supporting documents proving legitimate use cases.
Rotate inactive numbers out*of circulation temporarily if remediation stalls.

6️⃣ Encourage Prospectsto Save Your Number Post-Call
When recipients save your contact info, future calls bypass default spam filters. Train reps*to end conversations politely:
“Before we wrap up,would you mind saving our number under [Your Company Name]? This ensures you never miss critical updates!”*
Consider SMS follow-ups linkingvCardsfor one-click saving.This tactic boosted answer rates by ~22%in recent tests conducted by SalesHive teams.*
7️⃣ Prioritize TCPA/DNC ComplianceAbove All Else
Ignoring regulations destroys credibility:even accidental violations prompt penalties(upwards of $500 per incident)AND irreversible carrier blacklisting. Best practices include:
- Scrubbing leads against National Do Not Call Registry weekly.
- Training repson explicit consent requirements(e.g., opt-ins for SMS/voicemail drops)before outreach begins.
Investing in automated compliance tools reduces human error significantly.
