Numbers, agents and calls, in one account.

call2all gives you Indian phone numbers, AI agents that answer and make calls in eleven languages, a contact book, campaigns and triggers, and an API for all of it. You pay by the minute from a Prepaid Balance.

01Agents

An agent: instructions, a voice and a model

You write who the agent is and what it should do, in plain words. It answers your numbers, makes your outbound calls, looks things up while it talks and leaves a transcript, a summary and an outcome on every call.

Before you use an agent with customers, ring your own verified mobile with a test call from the editor.

Up to 12 outcomes you name (such as booked or call_back) and the fields you want captured.

02Numbers

Local +91 numbers with their own hours

Search by city and rent up to 50 numbers, at ₹499 a month each. Each number adds one line to your account; extra lines cost ₹299 a month and are shared by all your numbers.

Indian numbers need business verification first: a registration certificate and a GST certificate, checked by our licensed telecom partner. Searching needs no verification.

03Contacts

One contact book, one row per number

A number appears once in your account, whether it called you, you called it, or it came from a CSV, the API or a webhook. Its calls in both directions sit on the same record.

Imports take a CSV of up to 10 MB and 50,000 rows. You map the columns, the rows are matched on the number, and the report says exactly what happened to each one.

04Campaigns

The same call, to a whole list

Choose who to call (lists, tags or numbers), what they hear, when, and how many calls run at once: up to 50. Retry the people you didn't reach, up to five attempts in all.

Every campaign carries your statement that it is a service or transactional call. A new account's first three campaigns reach at most 1,000 people each.

05Triggers

Webhook URL
Your store, CRM or booking system posts to a private URL; the call is queued, after a delay if you set one.
Missed call
Someone rang one of your numbers and nobody answered: the agent calls them back inside your hours.
Date on a contact
A date held on the contact, such as appointment_at, comes due: call a set time before or after it.
Retry by outcome
The person said “call me later”: the agent calls back at the time they asked for.

06Calls

Every call, with what it cost

The call log holds every inbound and outbound call: who, when, how long, the transcript, a summary, the outcome, the fields the agent captured, and the recording.

Each call shows its list price, the discount from the recharge that paid for it, and the amount charged. The rate is fixed when the call starts, and calls are billed in 60-second blocks.

07API and webhooks

Your systems hear about every call

Everything above is in the REST API: create agents, rent numbers, sync contacts, queue calls, run campaigns and read the statement. Webhooks tell your systems when a call starts, ends and is analysed, when a campaign finishes, when someone opts out, and when your balance runs low.

Deliveries are signed, retried for 24 hours and listed in a delivery log you can replay. Resellers tag every resource with their own external_ref and metadata.

The default agent costs ₹4.50 a minute.
