How to Add Voicemail Forwarding and Transcription for a Twilio Number – BizStackPro Help

Voicemail Forwarding & Transcription for a Twilio Number

Q: How do I forward calls to voicemail in Twilio?

Leave the Call Forwarding field blank in BizStackPro Phone Number settings, then attach your voicemail TwiML configuration (via TwiML Bin/App) to the Twilio number so calls route to voicemail.

Q: Can I customize the voicemail message and have it transcribed?

Yes. Customize your TwiML using the verb and set transcribe="true" to generate a transcription (based on your Twilio settings and billing).

Configure voicemail routing and transcription for your Twilio numbers using TwiML Apps and TwiML Bins, and set BizStackPro correctly so calls route to voicemail the right way.

Making Sure Missed Calls Route Properly Instead of Disappearing

Missed calls can quickly turn into lost opportunities when voicemail routing is not configured correctly or callers never reach a working voicemail system.

BizStackPro voicemail handling depends on Twilio routing behavior, TwiML Apps or TwiML Bins, proper Voice & Fax configuration, and correctly managed call forwarding settings.

Without proper voicemail setup, businesses may lose customer messages, create broken voicemail experiences, fail to capture recordings, or miss important follow-up opportunities when calls go unanswered.

This guide explains how to configure voicemail forwarding, connect TwiML Apps or TwiML Bins, enable voicemail transcription, and stabilize voicemail routing behavior for Twilio numbers inside BizStackPro.

Before troubleshooting voicemail problems, it helps to understand how Twilio routing, call forwarding settings, TwiML Apps, TwiML Bins, and voicemail transcription work together inside BizStackPro phone systems.

Step 1: Update BizStackPro Settings

Before enabling Twilio voicemail handling, BizStackPro must allow Twilio to manage the incoming call instead of forwarding it to another number.

Go to: Settings → Phone Numbers

Leave the Call Forwarding number field completely blank.

Step 2: Build a TwiML App in Twilio

Next, create a TwiML App that controls your voicemail behavior.

Log in to your Twilio account.
In the left navigation menu, select Develop → TwiML Apps.
Click Create new TwiML App.
Enter a Friendly Name for your voicemail app.
Fill in the Voice (and optional Messaging) configuration details.
Click Create to finalize the app.

Step 3: Apply Your TwiML Bin/App to the Twilio Number

After creating your TwiML App (or TwiML Bin), attach it to the phone number that will receive voicemails.

Go to: Develop → Active Numbers

Select the phone number you want to modify.
Scroll to the Voice & Fax section.
Change the routing method from Webhook to TwiML Bin (or select your TwiML App if applicable).
Select the TwiML Bin/App you created for voicemail.
Click Save (typically in the bottom-left corner).

Pro tip: Call your Twilio number to confirm it goes directly to voicemail, plays the correct greeting, and accepts a recording.

Pro Tips

To generate a transcription, use the <Record> verb and set transcribe="true" in your TwiML.
Maximum voicemail length is typically 2 minutes.

Example: If you want a custom greeting, place a <Say> before <Record> in your TwiML so callers hear your message first.
