Yes. Interactive Voice Response (IVR) systems are fundamentally supported via our powerful Voice XML API platform. You can build highly dynamic, multi-layered branching trees and conversational menus.

Building Voice Menus

Vobiz does not limit you to a drag-and-drop web builder. Instead, you have full programmatic control by returning valid XML from your own backend webhooks.
  • Speech & DTMF input (<Gather>) - The core of any IVR is collecting user input. Prompt the caller (“Press 1 for Sales or 2 for Support”) or ask a free-form question (“How can I help you today?”). Vobiz fires a webhook back to your server containing the digits pressed or the transcribed speech text.
  • Text-to-Speech (<Speak>) - Combined with <Gather>, the <Speak> tag synthesizes prompts on the fly using neural AI voices across multiple languages - useful for variable content like account balances.
  • Playing audio (<Play>) - Point <Play> at an accessible MP3 or WAV URL to broadcast pre-recorded studio prompts or hold music.
  • SIP routing & transfer (call transfer methods) - Branch calls out via SIP based on user navigation. Connect to an external SIP trunk or E.164 number with <Dial>, or perform a native network-level blind/attended transfer via RFC 3515 SIP REFER if your endpoint supports it.
