Do you support IVR?
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 constrain you to a limited drag-and-drop web builder; instead, you have full programmatic control by returning syntactically valid XML from your own backend webhooks.
Speech & DTMF Input (`<Gather>`)
The core of any IVR is collecting user input. With the <Gather> tag, you can prompt the caller to "Press 1 for Sales or 2 for Support" (DTMF collection) or ask "How can I help you today?" (natural speech recognition). Once the user responds, 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 allows you to utilize dozens of neural AI text-to-speech voices across multiple languages to dynamically synthesize prompts based on database lookups (e.g., variable account balances).
Playing Audio (`<Play>`)
If you prefer to broadcast pre-recorded studio prompts or hold music, simply point the <Play> tag to an accessible remote MP3 or WAV URL.
SIP Routing & Transfer (SIP REFER)
Based on how your user navigates the IVR tree, you can seamlessly branch calls out via SIP protocol. You can connect the caller to an external SIP trunk or E.164 number using the <Dial> tag, or you can perform a native network-level blind/attended transfer if your connected endpoint supports RFC 3515 SIP REFER messaging.
