Programmable Voice
Place and receive calls, run IVR flows, send voice OTPs and text-to-speech alerts via a simple API.
Sometimes a call is the right channel — for a voice OTP, a critical alert, or an escalation from chat. WeZend's programmable voice lets you place and receive calls, build IVR menus, play text-to-speech in multiple languages, and route calls to agents, all as part of the same journeys and profiles the rest of the platform uses.
