Click the drop-down box and select the preferred number to appear on outbound calls.

Important: For most accounts, it is not necessary to set the Caller-ID settings at the user level in Callflows, this is now done in the SPBX app. If Caller-ID is set via CallFlows, leave notes on the account in SPBX.
