If you have multiple business Phone Numbers on your Tresta account, you can select which Phone Number you want your callers to see when you call them through your mobile app.
It's easy to select. On the Phone screen within your mobile app, the very top of the screen will show you the Phone Number that will display to callers. If you'd like to change this, simply click the drop-down and select the desired Phone Number.
If you do not see a Phone Number in the drop-down list, contact your System Admin so they can give you outbound dialing permissions on that Phone Number.
