📞 Best Practices to Reduce Spam Flags & Improve Call Answer Rates

Following the right calling practices can help improve your caller reputation, reduce the chances of your numbers being flagged as spam, and increase call answer rates.

✅ Maintain a Positive Caller Reputation

Keep Your Calling Lists Updated

• Regularly clean your contact lists
• Remove invalid or unreachable numbers
• Avoid repeatedly calling numbers that never connect

Provide Contact Information

Ensure customers can easily reach you or report concerns through:

• A callback number
• Support contact details
• Your business website

Avoid “Neighbour Spoofing”

Do not use phone numbers that mimic the recipient’s local area code or prefix to increase answer rates.

This practice is commonly associated with spam callers, and carriers actively monitor and flag such behaviour.

🔄 Be Consistent with Phone Number Usage

Avoid using the same phone number for multiple purposes, such as:

• Marketing campaigns
• Surveys
• Support callbacks

Using a dedicated number for each purpose helps carriers identify your traffic as legitimate.

Recommendation

If a number has been used for one campaign type, wait at least 45 days before reusing it for another purpose.

📈 Maintain Consistent Outbound Call Volume

Sudden spikes in call activity may trigger spam detection systems.

Best Practices

• Gradually increase call volume for new campaigns
• Avoid jumping from low to high traffic instantly
• Maintain stable outbound calling patterns whenever possible

Avoid Excessive Calling

Calls made too frequently or outside standard working hours are more likely to be flagged.

For example:

• Calling the same recipient excessively within a short timeframe may be considered harassment under regulations such as the Fair Debt Collection Practices Act (FDCPA).

Always respect customer communication preferences and applicable laws.

🛡️ Business Profile Registration (STIR/SHAKEN)

STIR/SHAKEN helps authenticate outbound calls and reduce caller ID spoofing.

This process verifies the authenticity of your calls using digital certificates, helping prevent your numbers from being marked as spam.

To Register:

Submit:

• Your business name
• Phone number details
• Proof of ownership

Once approved, your calls may appear as verified, improving customer trust.

⚠️ Important

Business Profile registration and STIR/SHAKEN registration are mandatory for users making calls with US phone numbers.

🏷️ CNAM Registration (US Numbers Only)

CNAM registration displays your business name as the caller ID during outbound calls.

This can:

• Improve answer rates
• Increase customer trust
• Reduce spam suspicious

Important Notes

• CNAM supports US local numbers only
• US toll-free numbers are excluded
• Business names are limited to 15 characters, including spaces

Processing Time

CNAM updates typically take 48–72 hours to reflect.

📢 Telemarketing & Advertising Compliance

If you use JotPhone for telemarketing or promotional calls, ensure that you:

• Obtain proper customer consent
• Clearly identify yourself or your organization at the start of the call
• Explain the purpose of the call clearly

Compliance requirements may vary by country and region. It’s recommended to consult legal counsel regarding applicable laws and regulations.
