Caller Display allows you to see a caller's phone or extension number, if available, before you answer. You'll need a caller display phone or unit to use it.

There is a one-off set up fee for Caller Display on Featureline. For further information or to order, go to our sales pages.


  • All external calls displayed are prefixed with a 9.
  • Numbers are not displayed for calls made with a BT Chargecard on a network that does not allow Caller Display or if the caller withholds their number.
  • If a caller is diverted to you using Call Diversion, the number of the phone that made the original call is displayed.
