Primary rule:
If the User (who logged in to send the SMS) is in your account's My staff tab and has a Twilio Number assigned to themselves, the lead will get the SMS from the Twilio number assigned to that User. If the Twilio number is SMS incapable, we use the default number to send out the SMS instead.

Go to your account Settings > My staff > Edit the user
Expand Call & Voicemail Settings
If the User (who logged in to the software) is not inside that account OR the User doesn't have a
Twilio number assigned, we will first use:
- Channel number (first Twilio number ever used with that contact)
If that number got removed, we will then use:
- Default outbound number
When we hover over the text messages in the conversation, we can click on the three dots to view Details. This helps to indicate which Twilio number is used when sending SMS.
