You can select a phone number to call forward. This will call forward for up to 5 telephone numbers, so you can choose which numbers you would wish to ring. This is an extra feature, and will count as another telephone number, however for those that needs to be assured to be reached no matter where they are, this might be an ideal solution. Call Forward can forward to any other number including those not in the PCS-1 service. You would need to set up call forward in the control panel.
