Build the campaign around the event, not the technology.
Sharad Navratri begins on Sunday, 11 October 2026. In Kolkata, the festival period is closely tied to Durga Puja. Maha Ashtami and Maha Navami fall on 19 October, with Vijayadashami on 20 October.
Local observances, puja schedules and ritual timings can vary by pandal, organiser and community. Match your call to the event you are actually promoting instead of using a generic “Navratri” message for every audience.
This approach works for very different businesses. A garment shop in Gariahat can call recent customers about a festive collection. A builder's sales office in New Town can invite prospects to a property event. An Indian grocery store in New Jersey can call Kolkata-origin customers about a festive offer. The workflow is similar; the audience, offer and script change.
20 ways to run a better Kolkata festival calling campaign.
Split your contacts by campaign.
Create separate lists for event registrations, existing-customer invitations, sponsorship enquiries, VIP guests and people who showed interest but did not register.
Tag every lead before the first call.
Useful tags include location, previous enquiry, preferred language, event type and whether the person has already registered.
Start with warm leads.
Call people who filled a form, messaged your business, attended a previous event or bought from you recently before testing cold lists.
Give the call one job.
For an event, the objective might be confirming attendance. For a retailer, it might be asking whether the customer wants festive offer details.
Use three qualification questions at most.
Ask whether the person is interested, whether they can attend and whether they want the details. Avoid turning a short call into an interview.
AI calling can do this: Route complex questions to a human.
Send sponsorship, bulk booking, pricing exceptions and customised package questions to your team instead of forcing the agent to improvise.
AI calling can do this: Follow up with interested leads.
A second call can ask whether the person received the information and whether they want to proceed, provided the follow-up is permitted.
Offer Bengali, Hindi or English.
Build the call around the language your audience actually uses. Troika Tech supports 9+ Indian languages for campaigns that need local-language calling.
Name the locality when it helps.
“Your event at Salt Lake” is more useful than “our Kolkata event” when the venue is fixed. Use the exact venue and landmark supplied by your team.
Keep Navratri and Durga Puja messaging distinct.
They overlap in the calendar but are not always described in the same way. Use language that matches the event and audience you are targeting.
Start registration calls before 11 October.
Use the days before Navratri to build registrations and reservations, then use the festival period for reminders and late conversions.
AI calling can do this: Run 24–48 hour reminders.
A reminder should contain the event name, date, location and one clear next step. Do not repeat the complete promotional pitch.
AI calling can do this: Follow up with selected no-shows.
If someone registered but did not attend, ask whether they want information about the next event or offer, subject to your campaign rules.
Track pickup, interest and qualified leads separately.
A high pickup rate is not a successful campaign by itself. Record answers, interest, registrations and human handoffs separately.
Set one target before you start.
If your event has 200 available registrations, build the campaign around filling that capacity rather than an arbitrary call-volume target.
Review the first 50–100 conversations.
Look for repeated objections such as the wrong date, inconvenient venue, price, unclear offer or language mismatch before scaling.
AI calling can do this: Apply your approved call flow.
Give the agent the exact offer, questions, approved answers and escalation rules rather than asking it to invent a sales pitch.
Record promotional preferences.
Give people a clear way to decline future promotional calls and record that preference so the person is not repeatedly contacted.
Check commercial-calling compliance before launch.
Review current consent, DND, registered-header and telemarketing requirements before uploading a promotional contact list.
AI calling can do this: Move leads through campaign stages.
Separate invitation, qualification, reminder, attendance and post-event follow-up so each lead receives the next relevant action.
Keep the calling flow short and measurable.
The agent should not replace your event team. It should handle repetitive first-stage conversations and send genuine buying or attendance intent to people.
Invite
Explain the event or offer in one short opening.
Qualify
Ask up to three questions tied to the campaign goal.
Register
Capture the next action and pass high-intent leads onward.
Follow up
Use approved reminders and post-event calls where appropriate.
What the AI calling agent should know
Give it the facts it needs to answer the first conversation without making it responsible for decisions your team has not approved.
Event facts
Date, time, venue, landmark, capacity and registration process.
Offer facts
Price, inclusions, eligibility, validity and exclusions.
Handoff rules
Which questions or lead types must reach a human immediately.
Localise the message before you increase call volume.
Kolkata campaigns can serve Bengali-speaking, Hindi-speaking and English-speaking customers. The most useful localisation is often simple: the right language, locality, venue and festival terminology.
Gariahat retailer
Call recent customers about a festive collection, store event or time-limited offer. Ask whether they want details before sending them onward.
New Town builder
Invite qualified property prospects to a festive open-house event. Route questions about pricing, inventory or site visits to a salesperson.
Event organiser
Call registrants to confirm attendance, answer basic event questions and identify sponsorship or bulk-booking enquiries.
Three rules for the Kolkata version
- Use Bengali, Hindi or English based on the audience.
- Use the exact venue and a useful local landmark.
- Call the event what the organiser calls it.
- Separate Navratri copy from Durga Puja copy where needed.
- Keep the offer and registration step identical across languages.
- Have a human available for questions the script cannot answer.
Measure the journey from answer to action.
Your dashboard should tell you what happened after the phone rang. Count connected calls, interested people, qualified leads and completed actions separately.
Conversation
Track calls attempted, answered calls and people who declined. This tells you whether your list and calling window are working.
Intent
Track people who asked for details, wanted a registration link, requested a human call or expressed a specific interest.
Outcome
Track registrations, attendance, appointments, sponsorship enquiries or sales separately from simple call engagement.
| Stage | What to record | What it tells you |
|---|---|---|
| Attempted | Calls placed | List and campaign volume |
| Connected | Answered conversations | Reach |
| Interested | Positive response or details request | Message fit |
| Qualified | Meets your campaign criteria | Lead quality |
| Converted | Registration, appointment or sale | Business outcome |

19 October matters particularly in Kolkata: it is listed as Durga Ashtami and Maha Navami in the local festival calendar. Individual puja organisers may follow different schedules, so verify the exact programme before putting timings into your call script.
Real examples and the practical lesson from each.
Troika Tech
Troika Tech describes event invitations, registration confirmations, festival promotions and lead qualification as AI voice use cases. Lesson: treat a festival campaign as a defined call workflow rather than simply “bulk calling.”
RabbitCalls
RabbitCalls describes workflows where an agent uses business FAQs and offers, conducts outbound campaigns and produces call summaries for follow-up. Lesson: prepare the information the agent needs before making calls.
NM Cloud Technologies
NM Cloud Technologies describes AI lead handling for jewellery businesses during festival demand spikes, including qualification, appointment booking and follow-up. Lesson: automate repetitive first-stage conversations while sending valuable prospects to people.
A 30-second script your team can start with.
Replace the placeholders and adjust the language to your audience. Keep the call focused on one action.
AI agent: “Hello [Name], I’m calling from [Business]. We’re inviting customers for our Navratri offer/event in Kolkata. We have [Offer] available for a limited period. Would you like me to share the details?”
Customer: “Yes, what is it?”
AI agent: “It is [Offer]. The event/offer is on [Date] at [Location]. Would you like the details and registration information?”
Customer: “Yes.”
AI agent: “Great. I’ll record your interest and arrange the next step. If you have questions, our team can speak with you. Thank you, [Name].”
Customer: “No, I’m not interested.”
AI agent: “No problem at all. Thank you for your time, [Name]. We won’t trouble you further about this offer. Have a good day.”
For a Troika Tech campaign, configure the agent around the approved script, qualification questions and escalation rules. Do not rely on an open-ended sales conversation for information your team has not approved.
Six checks before you press start.
- Event date, venue, offer and registration process are final.
- Contact list is segmented by source, audience and consent status.
- Bengali, Hindi or English script has been reviewed by a real team member.
- Three or fewer qualification questions and human-handoff rules are defined.
- DND, consent and applicable commercial-calling requirements have been checked.
- Pickup, interest, registration and conversion will be recorded separately.
Questions business owners ask before launching.
An AI calling agent is software that can make or receive phone calls, understand spoken replies and respond during the conversation. For an event campaign, it can handle repetitive invitation, qualification and reminder calls while routing selected conversations to your team.
They can call eligible leads with an event invitation, ask whether the person is interested, capture responses and follow up according to your campaign rules. They can also handle large numbers of repetitive calls without requiring your sales team to manually dial every contact.
Yes, depending on the calling system and configured voice flow. Troika Tech supports 9+ Indian languages, so a Kolkata campaign can be planned around Bengali, Hindi and English audiences rather than using one language for everyone.
Sharad Navratri begins on 11 October 2026 and runs through the Navratri period to Vijayadashami on 20 October. In Kolkata's festival calendar, Durga Ashtami is 19 October, with Maha Navami also falling on 19 October; Bengal-specific observances and puja timings should be checked against the individual puja organiser's schedule.
Give the agent a small set of questions tied to the outcome you want. For example, it can identify whether someone wants to attend, ask how many people are coming, and route a sponsorship or bulk-booking enquiry to a human.
Pricing depends on call volume, setup, telephony, integrations and the campaign workflow. Troika Tech operates in the ₹10–₹12 per-minute market range for AI calling, but your actual campaign cost should be calculated from expected connected-call minutes and the required setup.
Promotional calling is subject to India's commercial-communication rules, including applicable consent, DND and registered-telemarketer/header requirements. TRAI's current framework should be checked before each campaign, especially because the regulatory framework has been amended in 2026.
Put the campaign into production.
Start with the audience, offer and event date, not the technology. Finalise the list, script and qualification rules first; then use AI calling for the repetitive conversations and send genuine attendance or buying intent to your team. Troika Tech provides fully managed AI calling with a typical production deployment target of 3–7 days.
