How Flow Builder works

The building blocks of a call flow

Inbound call flows in Voiso are built using “nodes” — each representing actions such as routing, IVR, messaging, audio, voicemail, and more.

Nodes can be configured and linked together using our drag-and-drop builder to easily create entire call flows in just one interface.

Starting the journey with IVR

Easily configure IVR menus to help callers navigate self-service options with ease. 

Want to provide personalized call flow instructions to your callers? Simply upload your audio file and drop it into your flow — it’ll play automatically when customers phone in.

other nodes

With our Flow Builder tool, you can freely design your caller journey with any number of nodes to meet the precise needs of your callers.

Text-to-Speech (TTS):
Personalized Automation

67% of customers prefer self-service over speaking with an agent.

In Flow Builder, you can easily include real-time and natural-sounding text-to-speech (TTS) messages — using data from your CRM — to offer callers personalized and swift resolutions to their queries.
Self-service
Empower customers to check their order statuses, account balances, opening hours, booking information, and schedule appointments.
20 languages
Offer multilingual support in English, Arabic, Spanish, French, Turkish, and many more. Choose from male and female voices to suit your needs.
< 1 second
Provide lightning-fast and natural-sounding responses to customers with our near-real-time solution — no matter where in the world they are.

Personalize every call with ease

To enhance CX, you can personalize caller journeys with HTTP requests. These powerful nodes can collect external data (e.g. from a CRM) and include them in your flow for more efficient call handling.

    Caller ID & authentication

    Use an HTTP Request at the start of a flow to verify customer phone numbers and automatically display their details to agents as soon as the call is answered.

    Conditional routing

    Avoid putting existing customers through IVR menus and immediately connect them with the agents best-suited to handle their call.

    Self-service

    Enable customers to carry out actions such as account updates, checking orders or making appointment bookings using just their keypad.

FAQ

What is a Flow Builder?

A Flow Builder is a visual tool that drastically simplifies the process of creating custom call flows. Think of it like building with Legos –  instead of writing complex code, users drag and drop pre-built elements (widgets or modules) to define the steps and logic of their call flows.

How does a Flow Builder work?

Flow Builders provide a visual interface where you can drag and drop pre-built modules representing different steps in your call flow. Here’s a breakdown:

  • Start with a trigger: This is always an incoming call, first element in a call flow tool.
  • Drag and drop flow builder elements: These elements could be greetings, menus with voice prompts or touch-tone options, routing calls to specific departments or agents, playing messages on hold, or recording voicemails.
  • Connect the elements: You define the call flow by connecting these elements. For example, a greeting might connect to a menu with options for Sales or Support.
  • Set up options: Depending on the element, AI flow builder lets you define details like recording options for voicemails, time limits for menus, or overflow options if a queue is full.
