Make a forwarding phone number

Either use this service : https://app.burnerapp.com or…apparently Twilio does this neatly:

You can forward incoming calls from your Twilio number to another phone ==using Twilio Studio or a Twilio Function==. [1, 2]

Option 1: Forward Calls Using Twilio Studio (No-Code Method)

• Log in to the Twilio Console.

• Go to Studio > Flows and click the + (plus) icon to create a new flow.

• Select Call Forwarding from the template list (or start from scratch and use the Connect Call Towidget).

• Click on the forward widget and enter your destination phone number in E.164 format (e.g., +1followed by your 10-digit number).

• Click Save, then click Publish at the top of the flow.

• Navigate to Phone Numbers > Manage Numbers and select your Twilio phone number.

• Scroll down to the Voice & Fax section.

• Under A Call Comes In, select Studio Flow, choose your newly created call forwarding flow, and click Save. [1, 2, 3, 4]
