Voice

Voice on a SIP trunk we provision, or your own telephony account.

Programmable voice and IVR with Arabic text-to-speech, call masking, and voice OTP, on a SIP trunk we provision, or your own telephony account, and routed through vetted partners outside the region.

Capabilities

Everything from a single OTP call to a full call flow.

Programmable voice

Place and receive calls from your application through a single API, with full call event webhooks.

IVR

Build menu-driven call flows that route callers to the right team or the right answer, without a switchboard.

Text-to-speech

Natural-sounding speech generated on the fly, including Arabic, so you never have to record a prompt by hand.

Call masking

Connect two parties through a proxy number so neither side sees the other's real phone number.

Voice OTP

A spoken one-time passcode for the moments an SMS won't do, or hasn't arrived yet.

Call termination and origination

Route outbound calls and receive inbound calls on the same platform, priced per minute by country.

Routing

Your trunk or ours, partner routes outside the region.

Voice runs on a SIP trunk we provision for you, or on your own telephony account. Outside the region, calls are routed through vetted carrier partners so the same API still works.

Add voice to the channels you already use.
