You can select the number your contacts will see when you call them. Before making a call, it's important you verify the Amplemarket number you wish to contact from.
The default number you selected in your Calls settings (see article) will populate automatically when using the Amplemarket Dialer, but if you have more than one number assigned to you can always change it between calls.
You can do this In the Dial view, by clicking on the settings icon before placing a call. Here you can select between your assigned numbers.
Note that we will save the Amplemarket number selected when you are in a dialing session but when the session is over, we will always revert to the default number in your Calls settings.
