Programmable Voice

Build multi-level voice menus that greet, qualify and route every caller — designed as Callr Actions scenarios, with no telephony stack to run.

Bridge a customer and an agent in a single API call — turn any button on your site or app into a live phone call.

Bring several participants into one managed session, with per-leg control over who can speak and who only listens.

Collect and send keypad tones to capture menu choices, PINs or confirmations during a live call.

Detect answering machines automatically so outbound campaigns reach live people first — and leave the right message when they don’t.

Redirect, transfer, play audio or hang up an in-progress call from your backend, in real time over the API.

Send calls down different paths by opening hours, time zone and public holidays — no rule engine to build yourself.

Deliver a pre-recorded message to thousands of contacts at once, with delivery status reported back per call.

Originate and receive calls on the same platform and numbers, with full programmatic control over each leg.
