Caller ID control let's you select which number you want to display when call regular phones.
Because freespeech supports multiple numbers, you may want to select which number is displayed on the phone when calling to regular land lines and mobile.
Using caller id control you select any of your numbers from caller id display or restrict your caller id so it's not displayed. For example, if you have a local Dublin (01) number, you could select to have this displayed. The caller-id is set via your web control panel.
NOTE: Caller-id display to VOIP networks is controlled by your phone.
