- WhatsApp Business calling
- Outbound dialers
From request to live calls, in three steps.
Request access
Tell us what you are building. We set up your account and reserve an Indian number for you during the beta.
Create a trunk
One click in the console. You get SIP credentials and a server address to point your system at — that is the whole setup.
Connect and call
Drop the credentials into your stack, attach your number, and calls flow in both directions.
Everything you need to put calling in your product.
The telephony is ours to run; the product stays yours. You keep your stack, your servers and your call logic — we carry the calls.
Bring your own stack
LiveKit, Pipecat or the dialer you wrote yourself — if it speaks SIP, it connects. No SDK to adopt, nothing to rewrite.
Both directions, one trunk
Make and receive calls on the same credentials. Incoming calls are delivered straight to your servers, with ordered failover when you list more than one.
Compliance, built in
Indian telecom rules — caller identity, domestic routing — are enforced in our network, so you ship your product instead of reading regulation.
Capacity that scales
Every number you attach adds calling capacity to its trunk, and guardrails keep a traffic spike from touching the calls already in progress.
Credentials you control
Passwords issued once and stored encrypted, rotation that never drops a live registration, and API keys scoped to exactly what they need.
A console and an API
Point and click in the portal, or automate everything — trunks, numbers, credentials, call logs — through a REST API that feels familiar on day one.
Built for the people doing the integration.
Everything you can click, you can also script. Create trunks, attach numbers, rotate credentials and read call logs from code.
- A REST API that feels familiar from the first request
- Copy-paste quickstarts, filled in with your own trunk
- Scoped API keys and one-time secrets, built for CI as much as for people
