Voice & IVR

Contact center queues, IVR flows, Twilio webhooks, and call logs.

Syntra Voice handles inbound phone calls with configurable IVR menus, DTMF routing to queues, Twilio-compatible TwiML, and a console flow builder with live simulator.

GET/POST /v1/voice/queues — contact center queues

IVR flows

GET/POST /v1/voice/ivr/flows — create menus with digit → action mapping
Actions: queue, submenu, repeat, handoff, say_hangup, dial, voicemail

Console → Channels → Voice & IVR for visual editor and simulator

Webhooks (no API key)
