With Twilio Voice, customers call a real phone number and agents answer in their browser. 

What you'll need from your Twilio account:

* Account SID and Auth Token

* An API Key SID and API Key Secret (secure tokens to connect each agent to the call)

* A TwiML App and a Twilio phone number


## Steps to create a new Voice Channel inbox

1. In Chatwoot, create (or open) the "Voice Channel" inbox — *Settings → Inboxes → Add Inbox → Voice Channel*.
