✓ Applicable under TRAI's Telecom Commercial Communications Customer Preference Regulations (TCCCPR), as amended, which extend the same Promotional / Transactional (Service) treatment to Voice Calls that already applies to SMS.
Transactional / Service Voice Calls
- Ideal For: order confirmations, delivery/service updates, appointment reminders, payment or collection alerts, and OTP/verification calls to your own existing customers.
- Permitted 24x7x365, including on DND/NCPR-registered numbers, once your Voice Header and undertaking are approved.
- Requires a registered Voice Header (Sender CLI) on the DLT platform before dispatch — a Promotional Voice Header cannot be used for Transactional calls.
- Download the undertaking for sending Transactional Voice Calls, print on company letterhead, sign, and email a scanned copy to support@smsgatewayhub.com along with your username and the category of use.
- Script/recording approval is required before your first campaign; refer the sample templates guidance used for SMS as a starting reference.
- Billed per connected call on a 30-second pulse (see Billing Pulse under General below); busy, switched-off, unreachable or invalid numbers are not charged.
- Payment is 100% advance; GST @ 18% is mandatory on all packages.
- Credit validity: 1 Year from the date of purchase.
Promotional Voice Calls
- Ideal For: marketing announcements, offers and outbound campaigns to numbers that have not opted out of commercial communication.
- Permitted only between 10 AM and 9 PM as per TCCCPR; calls attempted outside this window are blocked by the network.
- Blocked on DND/NCPR-registered numbers unless the recipient has given explicit, recorded consent to receive promotional voice communication.
- Requires a separately registered Promotional Voice Header on the DLT platform — a Transactional Voice Header cannot be used to send Promotional calls.
- Repeated complaints or a high spam-reporting rate on a Promotional Voice campaign can lead to the Header/Entity being blacklisted on TRAI's DLT platform.
- Script/recording approval is required before your first campaign.
- Billed per connected call on a 30-second pulse (see Billing Pulse under General below); payment is 100% advance; GST @ 18% is mandatory on all packages.

General
- Billing Pulse: Voice Calls are billed on a standard 30-second pulse, in line with industry practice for Voice SMS/OBD in India. 1 credit = 1 pulse of up to 30 connected seconds — e.g. a 28-second message costs 1 credit, and a 45-second message crosses into the second pulse and costs 2 credits.
- Pulses are counted only from the moment a call is answered by the recipient; dialling, ringing, and unanswered/busy/switched-off attempts are never billed.
- Providers that bill on the attempted (dialled) duration rather than the answered duration will charge you for time the recipient never heard — ours does not.
- Do email us the payment details with transaction ID at support@smsgatewayhub.com.
- Setup fee applies for custom IVR / DTMF flows — confirm the amount with our sales team before recording your final script.
- Any changes in rules and regulations by TRAI or the Operator will be applicable with effect from the date of communication.
Important Awareness Notice: Don't be fooled by voice call providers selling calls below the industry standard by billing every dialled attempt as connected. Please stay away from those providers — we remain committed to industry-best service & support at the competitive, lowest possible price, billed only on successfully connected calls.
