All about Call Sign

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 >

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 - £5.82 a month
  • Two to four Calling Features - £10.31 a month
  • Five or more Calling Features - £13.49 a month
