Caller ID control let's you select which number you want to display when calling 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.
The default number presented is your 0844 number but with caller id control you can change this to any of your other numbers or restrict your caller id so it's not displayed. For example, if you have a local Manchester (0161) 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.
