What is Call Sign?
Call Sign lets you know who the call is for, or who is calling because calls from certain numbers will have a different ring tone.
Call Sign gives you an extra number with a different ring tone so you can make sure the right person answers the phone.
You can also add it to a Calling Features Pack, if there are other Calling Features you'd like to use. You can order it online now and check out our other calling features at www.bt.com/callingfeatures >
How much does it cost?
The monthly cost depends on how many calling features you have from those offered in the Calling Feature Pack. A 30-day minimum term applies. Line Rental Plus customers can choose to opt in to take the Calling Feature Pack at no extra cost.
- One Calling Feature - £5.57 a month
- Two to four Calling Features - £9.87 a month
- Five or more Calling Features - £12.91 a month
