Overview

Vobiz is a cloud-based telephony service provider that offers global reach with competitive pricing. Bananaflow AI’s Vobiz integration provides reliable voice connectivity for your conversational AI agents.

Prerequisites

Before setting up Vobiz integration, you’ll need:
  • A Vobiz account
  • Auth ID and Auth Token from your Vobiz dashboard
  • A Vobiz Application (optional – leave the field blank in Bananaflow and we’ll auto-create one for you on save, with the answer_url pre-set)
  • At least one Vobiz phone number

Configuration

Step 1: Get Vobiz Credentials

  1. Log in to your Vobiz dashboard
  2. Find your Auth ID and generate an Auth Token for API access
  3. (Optional) Navigate to the Applications section and create (or open) the application you’ll use with Bananaflow, then copy its Application ID. Skip this if you want Bananaflow to auto-create the application for you on save.
  4. Navigate to Phone Numbers and copy the numbers you plan to use

Step 2: Configure in Bananaflow AI

  1. Navigate to /telephony-configurations and click Add configuration
  2. Select Vobiz as your provider
  3. Enter your credentials:
    • Auth ID
    • Auth Token
    • Application ID – optional. Leave blank and Bananaflow will auto-create a Vobiz Application on save (with the answer_url already configured) and store its Application ID on this configuration.
  4. Click Save Configuration
  5. Open the configuration you just created and add at least one phone number (with country code, in E.164 format – + then country code then number, no spaces or dashes, e.g. +1234567890). The default caller ID is used for outbound calls.
    If Bananaflow auto-created the Vobiz Application for you, you still need to attach your Vobiz numbers to that application in the Vobiz Console under Applications. The auto-created application is named bananaflow-<random> – its Application ID is shown on the saved configuration.

Step 3: Test Your Configuration

  1. Create a test workflow
  2. Click “Call” to verify connection
  3. Check call logs for successful connection

Inbound Calling Setup

Vobiz numbers don’t carry an answer_url directly – the URL lives on a Vobiz Application, and each number is linked to one application. When you save an inbound workflow on a phone number, Bananaflow automatically pushes the webhook URL to your Vobiz Application’s answer_url (provided the credentials are correct). If Bananaflow auto-created the application during configuration save, the answer_url is already set and this push is a no-op.
  1. Log in to your Vobiz Console and open the Applications section
  2. Edit the application whose ID you configured in Bananaflow
  3. Attach the phone number you want to use for inbound calls
  4. Save

Step 2: Assign an Inbound Workflow to the Phone Number in Bananaflow

  1. Go to /telephony-configurations and open your Vobiz configuration
  2. In the Phone numbers section, edit the number that should receive inbound calls
  3. Set its Inbound workflow to the agent that should answer
  4. Save

Step 3: Verify the Answer URL on the Vobiz Application

  1. Open your Vobiz Console and navigate to Applications
  2. Open the application whose ID you configured in Bananaflow
  3. Confirm:
    • Answer URL is set to: https://app.bananaflow.ai/api/v1/telephony/inbound/run
    • Answer Method is POST
    Bananaflow pushed this URL automatically when you saved the inbound workflow in Step 2. The same URL is shared across every number linked to that application – Bananaflow routes each inbound call to the right agent based on the called number’s inbound workflow assignment. If the field is empty, shows a different URL, or Bananaflow surfaced a sync warning on save, the auto-push failed – most often because the Auth ID/Token or Application ID in Bananaflow is incorrect. Paste the URL into the field yourself, set the method to POST, and save.

Test Inbound Calling

  1. Call your configured Vobiz phone number from another phone
  2. Verify your Bananaflow AI voice agent answers and responds
  3. Check call logs in both Bananaflow AI dashboard and Vobiz dashboard

Troubleshooting

Ensure phone numbers include country code in E.164 format: +1234567890
  • Verify Auth ID and Auth Token are correct
  • Check for extra spaces in credentials
  • Ensure credentials haven’t been regenerated in Vobiz dashboard
  • Confirm your Auth Token matches exactly
  • Ensure audio pipeline is configured correctly
  • Verify the phone number is linked to the same Vobiz Application whose ID you configured in Bananaflow - Confirm the called number exists in your Bananaflow telephony configuration and has an Inbound workflow assigned
  • After assigning the inbound workflow, confirm Bananaflow successfully updated the application’s answer_url (no warning shown on save)
  • Confirm the phone number has an Inbound workflow assigned in /telephony-configurations - Check webhook signature validation is working (Auth Token in Bananaflow matches Vobiz dashboard) - Verify WebSocket connection establishes successfully - Review call logs for error messages

Best Practices

  • Test your configuration with a single call before running campaigns
  • Monitor Vobiz dashboard for usage and billing
  • Keep your Auth Token secure and rotate it periodically
  • Use a dedicated Vobiz Application for Bananaflow so the shared answer_url doesn’t conflict with other systems
