Anti-Spam & DND Policy
Standard operating procedures for National Customer Preference Register (NCPR) scrubbing, DND enforcement, telemarketing calling windows, and zero-tolerance policy towards unsolicited commercial communications (UCC).
Zero Tolerance for Unregistered Commercial Calls
Under the Telecom Commercial Communications Customer Preference Regulations (TCCCPR, 2018), making promotional calls or automated AI voice marketing to numbers registered on the National Do Not Disturb (DND) registry without explicit, verifiable consent is punishable by carrier blacklisting, CLI revocation, and financial disincentives up to ₹50,000 per violation.
Regulatory Foundation & Scope
7Silicon Group ("7Silicon Group", "we", "our") provides carrier-grade cloud telephony, virtual phone numbers (DID), concurrent SIP trunks, and autonomous AI voice agents. This Anti-Spam & DND Policy applies unconditionally to every client, enterprise, reseller, and end-user utilizing our voice infrastructure to initiate outbound voice calls across Indian telecommunication circles.
All voice telecommunications originate through licensed Access Service Providers (ASPs) and are strictly bound by the rules framed by the Telecom Regulatory Authority of India (TRAI) and the Department of Telecommunications (DoT), Government of India.
Classification of Voice Communications
Calls triggered by a direct user action (e.g., OTP delivery, order tracking, flight cancellation alerts, customer-requested callback, or critical security verification). These may be routed through registered virtual numbers (e.g. 9XXXX or 1600/1800 series) and are exempt from standard DND restrictions when explicit prior transaction context exists.
Any voice outreach intended to promote products, solicit investments, sell services, or generate commercial leads. Under TRAI regulations, these calls MUST ONLY originate from designated 140-series prefixes and must undergo automated real-time NCPR DND scrubbing prior to call initiation.
Calling Time Windows & Hours of Operation
Promotional calls are strictly restricted by TRAI to the following operational parameters:
- Permitted Hours: 10:00 AM to 09:00 PM Indian Standard Time (IST), Monday through Saturday.
- Strictly Prohibited Hours: 09:00 PM to 10:00 AM IST on all days.
- National Holidays: Outbound promotional campaigns are strictly disabled on Gazetted National Holidays.
7Silicon Group's platform-level automated rate limiters will automatically throttle or cancel outbound promotional campaign queues scheduled outside these statutory windows.
DLT Principal Entity & Consent Verification
Every client deploying outbound campaigns or inbound virtual numbers must maintain an active, verified Distributed Ledger Technology (DLT) Principal Entity (PE) registration with an authorized telecom operator (Airtel, Jio, Vodafone Idea, or BSNL).
- Clients must record and preserve timestamped consent logs (web opt-ins, physical forms, or recorded IVR consents) for at least 6 months.
- In the event of a TRAI or consumer complaint, the client must furnish verifiable proof of consent within 24 hours of notification from 7Silicon Group.
- Failure to furnish valid consent will result in immediate suspension of outbound calling privileges on that CLI.
Penalties & Disincentive Pass-Through
TRAI imposes graded financial disincentives on telecommunications providers for Unsolicited Commercial Communications (UCC) registered against any assigned CLI. 7Silicon Group operates a strict pass-through indemnity model:
| Violation Count | Statutory Fine / Penalty | Platform Action |
|---|---|---|
| 1st Offense | ₹1,000 per valid UCC complaint | Formal warning + 48h campaign pause |
| 2nd Offense | ₹5,000 per valid UCC complaint | CLI suspended for 7 days + audit required |
| 3rd+ Offense | Up to ₹50,000 + Carrier Blacklisting | Permanent CLI termination + forfeiture of security deposit |
Consumer Opt-Out Mechanism
Every promotional voice campaign must offer the recipient an immediate, cost-free mechanism to opt out of future communications (e.g., "Press 9 on your dialpad to unsubscribe from future calls"). Once a recipient presses the opt-out key, our system instantly appends the mobile number to the client's universal suppression list in real-time.
