  • One Calling Feature - £6.36 a month
  • Two to four Calling Features - £11.26 a month

The cost of the calls

Once you've ordered and activated Call Diversion, you’ll then be charged for the duration of any calls that are diverted, plus the standard call set-up fee. The call diversion cost per minute will be same as if you were making a call from your landline (outside of your calling plans inclusive calls). So the cost of a diversion will depends on:

  • The duration of the diverted call
  • The type of number you're diverting to. For example, diverting to a mobile number will cost more than a landline

Call Diversion with Call Minder or Voicemail

If you use Call Diversion with either of these services, then Call Diversion will take priority over the handling of the incoming call.
