Last Updated: 15 November 2025
Effective Date: 15 November 2025

This Fair Usage Policy (“FUP”) applies to all services provided by Tellimon Inc. (“Tellimon”, “we”, “our”), including:

  • Virtual Numbers (DIDs, Toll-Free, Mobile, UIFN)

  • SIP Trunking (Inbound & Outbound)

  • Cloud PBX / Routing

  • SMS & 2-Way Messaging

  • CPaaS API Services

  • Number Porting

  • Call Analytics

  • Hosted Telephony Services

This FUP ensures service quality, prevents abuse, and protects the stability of our global telecom network.
All customers (“you”, “your”) must comply with this FUP at all times.

Violating this FUP may result in traffic blocking, service limits, suspension, or termination.

1. PURPOSE OF THIS FUP

This Policy ensures:

  • Fair resource usage

  • Network reliability and protection

  • Compliance with international carrier rules

  • Prevention of fraudulent or excessive use

  • Equal access to all customers

  • Protection against service degradation

Tellimon services must be used responsibly and in line with global telecom regulations.

2. GENERAL FAIR USAGE PRINCIPLES

All usage must be:

  • Reasonable

  • Lawful

  • Consistent with typical business communications

  • Non-abusive

  • Non-excessive

  • Non-fraudulent

Any use that causes network strain, carrier blocking, or regulatory risk violates this FUP.

3. VOICE SERVICES FAIR USAGE

3.1 Call Volume & Pattern Restrictions

Tellimon may limit calls if:

  • CPS (Calls Per Second) exceeds plan limits

  • ASR (Answer Seizure Ratio) is unusually low

  • ACD (Average Call Duration) is abnormally short

  • Call attempts exceed normal human dialing behavior

  • Large bursts of calls are generated in short time frames

Examples of abusive behavior:

  • Dialing thousands of numbers in minutes

  • Predictive dialer activity without approval

  • Short calls (<3 seconds) repeated frequently

  • Traffic patterns resembling call blasting

3.2 Robocalls & Auto-Dialers

Robocalls, auto-dialers, predictive dialers, or outbound campaign tools require explicit approval.

Usage without approval violates this FUP.

3.3 Concurrent Calls

Concurrent call limits apply per plan.
Exceeding limits may result in:

  • Automatic blocking

  • Quality reduction

  • Temporary throttling

4. SMS & MESSAGING FAIR USAGE

4.1 SMS Volume & Rate Limits

Tellimon enforces:

  • Maximum SMS per second (SPS)

  • Daily volume thresholds

  • Anti-spam rate limiting

  • Carrier-specific throughput caps

Excessive bursts may trigger automatic throttling.

4.2 Content & Consent Requirements

To comply with carriers worldwide:

  • All SMS must be opt-in

  • Promotional SMS must follow local regulations

  • Sender IDs must be registered where required

  • SHAFT content (Sex, Hate, Alcohol, Firearms, Tobacco) is limited or banned

Failure to follow content rules violates this FUP.

5. VIRTUAL NUMBER USAGE FAIR RULES

5.1 Local Presence Restrictions

Some countries require:

  • Local business registration

  • Local address proof

  • Local use case justification

You must comply with all number-specific rules.

5.2 Inbound Call Limitations

Inbound call volumes must be reasonable and consistent with standard business usage.

Examples of abuse:

  • Using DIDs for high-volume call center traffic without approval

  • Generating artificial inbound traffic

  • Traffic pumping

5.3 Number Reselling

Reselling numbers without explicit permission violates this FUP.

6. CPaaS & API FAIR USAGE

6.1 Rate Limits

API calls must not exceed plan limits.
Abuse includes:

  • Excessive API polling

  • Uncontrolled automation

  • High-frequency SMS/Voice API bursts

You must secure your API tokens.
If compromised:

  • Tellimon may suspend usage

  • You remain liable for traffic generated

7. FRAUD, MISUSE & UNUSUAL ACTIVITY

Tellimon monitors:
