Can I use the BT Call Sign facility or business Direct Dial (DDI) numbers?
BT Call Sign lets you have two landline numbers on the same phone line, both giving a slightly different ring tone. If you nominate one of them as being the destination number you can identify how to answer the call if you work from home for example. We advise you to get in touch with BT to confirm that Call Sign is available for you and then login to My Windsor or your Targetmaster service to redirect the calls to go to your relevant Call Sign number. Equally, DDI phone numbers are simply another landline that routes to an extension using your own switchboard facilities, so they are compatible also.
