DLT Registration for 160 Series Calls: Complete BFSI Guide

Last updated on July 15th, 2026 at 02:33 pm

For BFSI entities, DLT registration for 160 series calls is the single biggest operational bottleneck when migrating away from standard 10-digit numbers. In my practice advising telecom-sector clients, I have seen entities acquire their 1600 numbers from the Telecom Service Provider (TSP) and then wait weeks. DLT template approvals stall, and the first compliant call keeps getting pushed back. Understanding the process end-to-end saves that time. Moreover, it eliminates the significant compliance risk that delay creates. The underlying driver behind this migration is often a low call pickup rate on standard 10-digit numbers, a problem the 160 series is specifically designed to address. Consequently, this guide walks your compliance team through every step.

• DLT registration is a legal prerequisite under TCCCPR 2018. No entity may make a 160-series call without a valid Entity ID. It also needs a registered CLI and an approved content template on a TRAI-approved DLT platform.
• Registering on one major DLT platform (Airtel, Jio, Vi, or BSNL) syncs your Entity ID, headers, and templates. All interconnected platforms then share this information. You only need to register once.
• Template approval is the longest step. It typically takes 3 to 7 business days per platform. However, rejections for naming errors or variable-format issues can extend this to 2 to 3 weeks for first-time registrants.
• Every voice script used in a 160-series call must carry a valid Template ID in the call signalling. Calling with an unregistered or blacklisted template is a violation. This holds true regardless of whether your number is itself a valid 1600 allocation.
• BFSI entities must also implement routing segregation at the system level. The same dialer cannot route 140-series promotional traffic and 160-series transactional traffic through the same number pool.

Quick Answer: DLT registration for 160 series voice calls requires a BFSI entity to register as a Principal Entity on any one TRAI-approved DLT platform (Airtel, Jio, Vi, or BSNL), upload KYC documents, register the 1600 CLI as a voice header, pre-register every call script as a content template, and link the template to the CLI before making the first compliant service or transactional call.

What Is DLT Registration for 160 Series Calls?

DLT registration for 160 series calls is the mandatory process for Principal Entities. Through this process, specifically, a PE registers its business, its outgoing caller line identification (CLI), and its voice call scripts on a blockchain-based platform. A TRAI-authorised Telecom Service Provider (TSP) operates that platform. The registration creates an auditable, immutable ledger record. Specifically, it records every entity the regulator authorises to make 160-series calls and every script that entity may use.

The TCCCPR, 2018 makes DLT registration a legal precondition for all commercial voice communications in India. The substantial Second Amendment dated 12 February 2025 reinforced this obligation. The DoT Press Release dated 30 May 2024 (PRID 2022249) confirmed this directly. Specifically, TSPs must verify every entity before assigning a 160-series number. Additionally, the entity must undertake to use the number only for service and transactional calls. The DLT platform operationalises that undertaking. Specifically, every call script receives pre-registration as a content template with a unique Template ID. Consequently, that ID must accompany each call in the signalling layer.

In practice, this means your compliance team carries two parallel obligations. First, procure the 1600 number from your TSP. Second, complete DLT registration. Specifically, the number must have at least one approved content template mapped to it before any call goes out. Completing only one of these two steps does not constitute compliance.

Most BFSI compliance teams lose 2 to 3 weeks on avoidable DLT errors. FreJun’s legal and compliance team has guided banks, NBFCs, and insurers through end-to-end DLT setup and 1600 number activation. Book a session to walk through your entity’s specific registration path.

Who Must Complete DLT Registration for 160 Series?

Every entity that holds or plans to hold a 160-series number must complete DLT registration as a Principal Entity. This applies to both existing and new 1600-series number holders. The TRAI Direction dated 19 November 2025 (PRID 2191647) issued phase-wise adoption mandates. These apply to entities that RBI, SEBI, and PFRDA regulate. Subsequently, a follow-up Direction dated 16 December 2025 (PRID 2205350) extended the same mandate to IRDAI-regulated insurers.

BFSI Entities Covered

• RBI-regulated entities: Commercial banks (public sector, private sector, foreign banks), NBFCs, small finance banks, payment banks, and microfinance institutions making service or transactional voice calls.
• SEBI-regulated entities: Mutual funds and Asset Management Companies (AMCs) faced a deadline of 15 February 2026. Qualified Stockbrokers (QSBs) face a deadline of 15 March 2026 per PRID 2191647.
• PFRDA-regulated entities: Pension funds, National Pension System (NPS) service providers, and Point of Presence (PoP) entities.
• IRDAI-regulated entities: Life insurers, general insurers, health insurers, and insurance intermediaries.
• BPOs and recovery agencies: These entities do not hold their own 1600 numbers. Instead, they must use the Principal Entity’s allocated 1600 number and therefore must operate under the PE’s DLT registration as a Telemarketer (TM). The PE remains vicariously liable for every call its agents make.

What this means for your compliance team is straightforward. Consider any outbound voice call your organisation makes to a customer: account alerts, OTP delivery, EMI reminders, policy renewals, or any other service or transactional purpose. In all these cases, you must complete DLT registration and have an approved voice template in place before that call goes out.

Which DLT Platforms Are TRAI-Approved for 160 Series?

TRAI authorises major TSPs to operate DLT platforms. All platforms connect through a common blockchain layer. Therefore, registering on any one platform syncs your Entity ID, CLI headers, and content templates across all operators. You register once, and consequently your credentials receive recognition network-wide.

TRAI-Approved DLT Portals

Operator	Platform Name	Portal URL
Airtel	DLT Connect	dltconnect.airtel.in
Reliance Jio	TrueConnect	trueconnect.jio.com
Vodafone Idea (Vi)	Vilpower	vilpower.in
BSNL	UCC-BSNL	ucc-bsnl.co.in
Videocon / STPL	SmartPing	smartping.live

For BFSI entities, aggregators most commonly recommend Airtel and Jio due to their faster approval turnaround and more detailed documentation portals. That said, the choice of platform does not change the legal outcome. Any approved registration satisfies the TCCCPR obligation. The practical step is to select the platform where your primary TSP operates. That TSP’s support team can then assist with technical queries directly on the same platform.

What Documents Do You Need for DLT Registration?

Document accuracy at the DLT registration stage is the most frequent cause of rejection and delay. Entity name mismatches between the PAN card and the registration form cause a large share of first-submission rejections. Therefore, prepare every document before opening the portal, not during the form-filling process.

Mandatory Documents for Principal Entity Registration

• PAN Card of the entity: The entity name on the PAN must exactly match the name in the DLT registration form. No abbreviations, no trade name variations.
• GST Registration Certificate: Mandatory for all GST-registered entities. Confirms active tax status and business address.
• Certificate of Incorporation or equivalent: For companies, the MCA Certificate of Incorporation. For NBFCs, also include the RBI Certificate of Registration. For insurers, include the IRDAI registration certificate. For AMCs, include the SEBI registration certificate.
• Authorised Signatory identity documents: PAN card and Aadhaar card of the individual the entity authorises to sign on its behalf.
• Letter of Authorisation (LoA): A board-signed or company-sealed letter naming the individual who will complete DLT registration on behalf of the entity.
• Business address proof: Utility bill, lease agreement, or bank statement showing the registered business address.
• Contact details: Primary email address and mobile number for OTP-based verification during registration.

Additional Documents for BFSI Entities

For entities in the 1601 sub-prefix bracket (RBI, SEBI, PFRDA, IRDAI regulated), the TSP’s DLT verification team will additionally request the sectoral regulator’s registration or licence document. For example, an NBFC must attach its RBI Certificate of Registration. Furthermore, the TCCCPR Second Amendment dated 12 February 2025 requires the entity to confirm in writing its undertaking. Specifically, the entity undertakes to use the 160-series number exclusively for service and transactional calls. Most TSPs build this undertaking into their DLT onboarding form. However, your legal team should review that form before the authorised signatory executes it.

Step-by-Step: How to Complete DLT Registration for 160 Series Calls

The DLT registration process for 160-series voice calls has six sequential stages. Each stage must be complete before the next can begin. For first-time registrants, the total calendar time from first submission to first approved call is typically 2 to 4 weeks. That said, this varies by platform and document accuracy.

Stage 1: Select Your DLT Platform and Create an Account

Navigate to your chosen TSP’s DLT portal. Select the entity type as Enterprise or Principal Entity (the exact label varies by platform). Provide the entity’s legal name exactly as it appears on the PAN card. Use a dedicated compliance email address rather than a personal inbox. All approval notices, rejection notices, and Template IDs go to this address.

Additionally, set up two-factor authentication on the DLT portal account immediately after creation. The reason is straightforward: the DLT platform holds the Template IDs that drive your call routing. Unauthorised access would allow a third party to deactivate your templates. This would disrupt all 160-series calls immediately.

Stage 2: Submit KYC Documents and Pay the Registration Fee

Upload all documents from the previous section. Most platforms charge a one-time registration fee. Amounts vary by platform, so verify the current fee schedule on the portal at the time of registration. Payment channels include debit card, credit card, net banking, and, on most platforms, cheque or demand draft.

Account verification typically takes 1 to 2 working days after a complete document submission. If the platform requests additional documents, respond within the same business day. Otherwise, further delays accumulate. The clock on your compliance deadline does not pause during DLT processing.

Stage 3: Register Your 1600 CLI as a Voice Header

Once the platform approves your PE account, navigate to the Header or Sender ID section. A voice CLI for 160-series calls registers as a numeric header. This differs from a 6-character alphanumeric Sender ID, which is the SMS format. Select the voice category, enter the 10-digit 1600 number your TSP allocated, and link it to your approved Entity ID.

Each 1600 number requires separate registration as a header. If your entity holds multiple 1600 numbers, each one needs its own header registration. For example, separate numbers for OTP delivery, EMI reminders, and policy renewal calls all require individual registration. Header approval typically takes 1 to 2 working days.

Stage 4: Register Content Templates for Every Voice Script

This is the most time-consuming stage and the one most commonly mishandled. Navigate to the Template section of the DLT portal. Next, select the template type. Use Service Explicit or Service Implicit for service calls. Use Transactional for OTPs and account alerts the customer triggers within 30 minutes. Voice templates follow the same type taxonomy as SMS templates under the TCCCPR. Therefore, using the wrong type classification for a voice script is a violation in its own right.

Enter the script text for the voice call. Specifically, variable fields such as customer name, account number, or OTP value must use the prescribed variable syntax. Free-text variables face automatic rejection. Every template must include the brand name of the entity. Submit the template for approval. Upon approval, the DLT platform assigns a unique Template ID. Record this ID immediately. Your telephony system or IVR must then pass this Template ID in the call signalling for every call that uses that script.

Stage 5: Bind the Content Template to the CLI Header

Template approval and CLI header approval are two separate events. After both receive approval, therefore, you must explicitly link the template to the header within the DLT portal. Many first-time registrants skip this binding step. Consequently, their calls face network-level blocking even though both the number and the template already hold individual approval.

For BFSI entities with large template libraries, individual binding is critical. For instance, a bank may have separate IVR scripts for EMI reminders, OTP delivery, account alerts, and fraud warnings. Each template must bind to the relevant header individually. A single header can link to multiple templates, but each binding needs explicit confirmation.

Stage 6: Validate End-to-End With a Test Call

Before routing live customer traffic through the 1600 number, make a test call through your TSP first. This confirms that the Template ID passes correctly in the signalling layer and that the network does not block or flag the call. Document the test call with a CDR entry and the Template ID. Consequently, this creates an audit trail confirming that your DLT integration was validated before go-live.

How Do You Register a Voice Content Template on DLT?

Voice content template registration on DLT follows the same foundational rules as SMS template registration. However, it carries additional obligations unique to voice calls. The TCCCPR Second Amendment dated 12 February 2025 extended the template registration obligation explicitly to voice call scripts, not just SMS messages. This distinction is important. Indeed, many BFSI compliance teams initially miss it.

Template Type Classification for Voice Calls

Template Type	When to Use	Example
Transactional	Triggered within 30 minutes of a customer-initiated event	OTP for login, transaction confirmation PIN
Service Implicit	Service calls to existing customers within the contractual relationship	EMI due date reminder, account balance alert
Service Explicit	Service calls requiring explicit consent not covered by the existing contract	Policy renewal call to a lapsed customer, debt collection follow-up

Content Rules for Voice Templates

Every registered voice template must include the brand name of the entity. Templates without the brand name receive rejection at submission. Variable fields must use the platform’s prescribed syntax. For example, variables such as customer name or account number insert as tagged placeholders, not as free text. The variable count and type must match what the IVR or agent dialer will inject at call time.

Additionally, auto-dialer and robo-call scripts must include a disclosure at the start of the call confirming that the communication is automated. The TCCCPR Second Amendment, 2025, mandates this disclosure. Furthermore, the registered template text must reflect it, not just the calling system’s runtime behaviour. Templates that omit this disclosure for automated calls face a non-compliance finding. This applies even if the DLT portal approved them. In other words, the actual call still deviates from the registered template.

Approval Timeline and What to Do If a Template Is Rejected

Template approval typically takes 3 to 7 business days from submission. Rejections usually occur for one of four reasons: the brand name is missing, a variable uses incorrect formatting, the template type is misclassified, or the script contains promotional language in a service template. Upon rejection, the portal displays a rejection reason code. Address the specific reason before resubmitting. Do not simply resend the unchanged template. In my experience advising clients on this process, the most reliable approach is clear: have a compliance officer review the draft template against the DLT portal’s guidelines before the first submission. Fixing errors before submission is always faster than fixing them after rejection.

Consent Template Registration: What BFSI Entities Must Know

Consent template registration is a separate, parallel obligation on the DLT platform. It is distinct from content template registration. Specifically, it addresses how the entity captures and records the customer’s agreement to receive calls.

BFSI Consent Rules Under the Second Amendment, 2025

The TCCCPR Second Amendment dated 12 February 2025 tightened consent rules significantly for BFSI entities. Your consent template registration must align with these specific rules. Implicit consent for service calls remains valid only for the duration of the underlying contract between the entity and the customer. In other words, once the contract ends, so does the consent. Explicit consent for purposes the contract does not cover stays valid for only 7 days from the date of grant. After those 7 days, the entity must re-obtain consent. Once a customer opts out, the entity cannot contact them again for the same purpose for 90 days from the opt-out date. Importantly, this 90-day lockout applies per purpose, not per entity.

In practice, this means your consent templates must be purpose-specific. A single blanket consent template covering all voice communications does not satisfy the TCCCPR requirement. Instead, each communication purpose needs its own consent template. For example, a bank needs separate consent templates for collections calls (service explicit), product renewal reminders (service explicit), and OTP delivery (transactional). Moreover, each must receive individual registration on the DLT platform. It must also map to the corresponding content template.

Common DLT Registration Errors and How to Fix Them

These are the errors I see most frequently when BFSI clients approach me after a failed or stalled DLT registration process. Each one is avoidable with the right preparation.

Error 1: Entity Name Mismatch

The entity name in the DLT registration form does not exactly match the name on the PAN card. This is the most common rejection reason. The fix is simple: cross-reference the PAN card before filling the form and use the exact legal name with no abbreviations or trade name variations.

Error 2: Incorrect Template Type Classification

A service implicit call gets submitted as a transactional template, or a promotional call script goes in as a service implicit template. Template type misclassification is a regulatory violation. Notably, this applies regardless of whether the DLT platform approves the template. The fix requires your compliance team to classify each script against the TCCCPR definitions before submission. If the call is an EMI reminder to an existing borrower, classify it as service implicit. If it is an OTP the customer’s own login action triggered within the last 30 minutes, classify it as transactional.

Error 3: Missing Brand Name in Template

The DLT platform requires every content template to include the entity’s brand name. Scripts that open with a generic greeting such as “Your EMI is due” without identifying the calling entity receive rejection. The fix is to ensure every template script begins with or prominently includes the entity’s registered brand name, for example “HDFC Bank: Your EMI of Rs X is due on [date].”

Error 4: Template-to-Header Binding Skipped

As the step-by-step section explains, some entities approve both the template and the CLI header but never explicitly bind them together in the DLT portal. Consequently, calls face network-level blocking despite valid individual approvals. Therefore, the fix is to treat the binding step as a mandatory checklist item. Specifically, confirm it with a screenshot or portal audit log before going live.

Error 5: Promotional Language in a Service Template

A script containing phrases such as “upgrade your plan”, “limited-time offer”, or “exclusive benefit” will face rejection as a service template and may trigger manual review. Moreover, making a call from a 1600 number using a promotional script creates a dual violation. First, it breaches the purpose restriction on the 160 series. Second, it breaches the template registration requirement. The fix is to have your legal team review every script for promotional language before DLT submission.

Error 6: Using a 1600 Number Before Template Approval

Some entities receive their 1600 number from the TSP and begin routing calls before DLT template approval is complete. TRAI treats this as an unregistered commercial communication. As a result, it triggers the Unregistered Telemarketer enforcement path under the TCCCPR. The fix is straightforward: do not route any live customer traffic through the 1600 number until at least one content template has approval. That template must also have binding to the CLI header and end-to-end test validation.

What Happens After DLT Registration Is Complete?

Completing DLT registration marks the beginning of an ongoing compliance obligation. It is not a one-time event. After initial registration, the following recurring obligations apply to every entity holding a 1600 number.

Ongoing Template Maintenance

Every new call script must receive registration as a new content template before use. Entities that build new IVR workflows or update existing scripts must submit the revised template for approval. They must then obtain the new Template ID before deploying the script. In a large bank or NBFC with a continuously evolving IVR library, DLT template management must integrate into your change management process. Otherwise, standalone treatment creates compliance gaps.

CDR Retention and Template ID Mapping

The TCCCPR requires entities to retain Call Detail Records (CDRs) for the period the TSP’s licence conditions specify. However, RBI and other sectoral regulators typically require longer retention periods. Moreover, each CDR entry must map to the Template ID the entity invoked for that call. Indeed, both compliance audits and consumer complaint responses depend on this mapping.

Consent Record Uploads

Where explicit consent forms the basis for a call, therefore, the entity must upload the consent record to the DLT platform under the Digital Consent Acquisition framework. Consent records must be purpose-specific, timestamped, and linked to the corresponding consent template. Notably, uploading a batch consent record for all customers rather than individual purpose-specific records does not satisfy the TCCCPR requirement.

Routing Segregation: The Technical Obligation Most Entities Miss

DLT registration alone does not make a BFSI entity compliant. The TCCCPR and the DoT Press Release of 30 May 2024 (PRID 2022249) impose a separate technical obligation: routing segregation. The same dialer instance cannot route both 140-series promotional calls and 160-series service or transactional calls through the same number pool. Furthermore, this segregation must operate at the system level, not just on paper. A policy document stating this requirement does not satisfy it.

What Routing Segregation Requires in Practice

Separate outbound trunks must carry 140-series and 160-series traffic. Specifically, marketing campaigns and OTP delivery cannot share the same outbound trunk. Additionally, the dialer’s routing logic must prevent a 1600 number from serving as the originating CLI for a promotional call. Similarly, it must prevent a 140 number from handling a service or transactional call. Compliance auditors consistently hold that a written policy without enforced routing logic does not satisfy this obligation.

For BFSI entities using third-party BPOs or cloud telephony platforms, the entity must verify that the vendor’s infrastructure enforces this segregation technically. An SLA clause alone is not sufficient. Ultimately, the Principal Entity carries vicarious liability for every call its vendors make using its 1600 number.

How FreJun Helps BFSI Teams With DLT Registration

FreJun is a cloud telephony and AI-powered calling platform built for BFSI, SaaS, and enterprise teams operating under India’s regulatory framework. For the 160-series compliance journey specifically, FreJun’s platform addresses the three layers that most entities struggle with: DLT integration, routing segregation, and CDR-to-Template-ID mapping.

DLT-Native Integration

FreJun’s platform integrates natively with TRAI-approved DLT platforms. Consequently, Template IDs store at the trunk level and automatically pass in call signalling for every outbound 1600 call. Furthermore, new scripts go to the DLT platform directly through FreJun’s interface. As a result, this eliminates the manual portal-switching that typically causes binding errors and delays. Teams appreciate this time saving.

Routing Segregation by Design

FreJun enforces 140-series and 160-series segregation at the infrastructure level. Separate outbound trunks carry each traffic type. The routing engine prevents cross-series CLI assignment. Furthermore, FreJun integrates with HubSpot, Zoho CRM, Salesforce, and LeadSquared, so call disposition data, Template IDs, and CDR entries flow automatically into your CRM audit trail.

Compliance Team Guidance

FreJun’s legal and compliance team assists BFSI entities through the DLT onboarding process: document preparation, template drafting, type classification review, and post-registration template management. This is not legal advice and FreJun does not act as legal counsel. However, the operational guidance significantly reduces the document error rate and the time to first approved call in practice. In the telecom-sector engagements I have worked on, a guided DLT registration typically completes 10 to 14 calendar days faster. That time saving alone often justifies the engagement.

Frequently Asked Questions

What is the difference between DLT registration for 160 series versus 140 series calls?

Both series require Principal Entity registration and content template pre-registration on a TRAI-approved DLT platform. However, 160-series registration additionally requires the entity to be a regulated Principal Entity (bank, NBFC, insurer, or similar). It also requires a numeric voice CLI header rather than an alphanumeric Sender ID, and sectoral regulator credentials as part of TSP verification. The 140-series is open to all registered telemarketers for promotional calls. The 160-series restricts to verified BFSI entities for service and transactional calls only.

What penalty applies if an entity makes a 160-series call without an approved DLT template?

Under the TCCCPR Second Amendment dated 12 February 2025, financial disincentives per violation instance are Rs 2,00,000 for the first violation, Rs 5,00,000 for the second, and Rs 10,00,000 for the third and subsequent violations. Additionally, if 5 valid complaints arise in any rolling 10-day window, the entity faces outgoing service suspension across all its telecom resources for up to one year. For a BFSI entity, this means OTP delivery, customer alerts, and collections calls all stop simultaneously.

How do you apply for a 1600 number in India?

A BFSI entity applies for a 1600 number directly through its Telecom Service Provider (TSP). The TSP must verify the entity’s eligibility before assigning the number, per the DoT Press Release of 30 May 2024 (PRID 2022249). The entity must provide its sectoral regulator’s registration certificate, sign a formal undertaking to use the number only for service and transactional calls, and complete DLT registration as this guide describes before making the first call.

How long does DLT registration take for a 160-series voice call setup?

PE account approval typically takes 1 to 2 working days after complete document submission. CLI header registration takes a further 1 to 2 days. Content template approval takes 3 to 7 business days per template, though rejections for naming or variable errors can extend this. Total calendar time from first submission to first approved call is typically 2 to 4 weeks for first-time registrants with clean documents, and 3 to 6 weeks when rejections occur.

Do BPOs and recovery agencies need their own DLT registration for 160-series calls?

No. A BPO or recovery agency does not hold its own 1600 number. It must use the Principal Entity’s (the bank’s or NBFC’s) allocated 1600 number. The agency registers on the DLT platform as a Telemarketer (TM) and operates under the Principal Entity’s DLT registration through a PE-TM chain. The Principal Entity remains vicariously liable for every call the agency makes using its 1600 number, under the TCCCPR and the RBI Fair Practices Code.

Can the same template be used across multiple 1600 numbers held by the same entity?

Yes. A single approved content template can bind to multiple CLI headers within the same entity’s DLT account. However, each binding must receive explicit confirmation in the DLT portal. A template that the entity approves on one CLI header does not automatically become available on other headers the same entity owns. Your DLT portal audit log should confirm that every active 1600 number has at least one approved and bound template before go-live.

What happens if an entity uses a template that the DLT platform has blacklisted?

Using a blacklisted template is a TCCCPR violation regardless of whether the 1600 number itself holds valid allocation. The TSP’s DLT scrubbing layer blocks the call at the network level. In addition, the entity faces the same financial disincentive schedule as any other TCCCPR violation: Rs 2,00,000 for the first instance, rising to Rs 10,00,000 for the third and beyond. Entities should set up automated monitoring to flag template expiry or blacklist events before they affect live call traffic.

Key Takeaways

• DLT registration is a legal prerequisite under TCCCPR, 2018 for every entity using a 160-series number. Acquiring the number from the TSP without completing DLT registration does not constitute compliance.
• Registration follows six sequential stages: account creation, KYC and fee submission, CLI header registration, content template registration, template-to-header binding, and end-to-end test validation.
• Template approval is the longest and most error-prone stage. Common errors include entity name mismatches, missing brand names, incorrect template type classification, and the frequently missed binding step.
• Consent templates are a separate, parallel obligation. Each communication purpose requires its own consent template, aligned with the 7-day explicit consent rule and 90-day opt-out lockout from the Second Amendment, 2025.
• Routing segregation is a technical obligation, not a policy one. The same dialer cannot carry 140-series promotional traffic and 160-series transactional traffic. The boundary must operate at the infrastructure level.
• After registration, DLT template management becomes an ongoing compliance function. Every new IVR script needs a new DLT template before use, and CDR entries must map to Template IDs for the audit trail.
• Phase deadlines are live. SEBI-regulated Mutual Funds and AMCs had a deadline of 15 February 2026 and Qualified Stockbrokers a deadline of 15 March 2026 per TRAI Direction PRID 2191647. Entities that have not yet completed DLT registration are already in the enforcement window.
