Call recording options with unlimited storage (price per month)

up to 7 years £7.00
up to 5 years £5.00

up to 3 years £3.50

The price for broadband, line rental, call plans and call charges will be increased each March from 2022 by the Consumer Price Index (CPI) rate of inflation published by the Office for National Statistics in January of that year, plus 3.9%.

There are two members of the BT One Phone family: BT One Phone Office and BT One Phone Professional.

BT One Phone Office replaces your office phone system with a Cloud-based one – creating communications solutions whilst maintaining the call centre and centre solutions software code of practice. A dedicated private mobile network, installed in your office, gives guaranteed mobile UK call coverage and call forward capacity – so you can use your mobiles without fear of losing signal with a phone line, and with guaranteed call quality as your branch offices communicates with clients and customers.

Thanks to VoIP solutions, your people will have access to all the call management features they expect from their desk phones, through their mobiles.

BT One Phone Professional uses the BT One Phone Cloud-based VoIP phone system to give your mobile workers the same access to call management features that they rely on in the office, no matter where they are in the UK. (This does not replace your office phone or telephone system).

Small businesses depend on their phone number. It’s known to existing customers and widely advertised to attract new ones.

PhoneLine+ has been specifically designed to replace your traditional landline service using VoIP technology to deliver voice calls over the broadband network, all at a highly competitive price – available now at a Special Introductory Price (See below).

PhoneLine+ can be accessed on a choice of devices including computers, tablets, smartphones and IP handsets, or via an adaptor for your current phone, so there is no need to invest in new equipment unless you want to.

It supports all the key features expected of a traditional telephone system including voicemail, call divert and call hold, as well as other features designed to make your life easier.

As well as future-proofing your business, you’ll be able to:

  • improve customer experience and retention
  • keep your existing landline phone number
  • use your choice of devices and add the app on to your smartphone so you can take and make calls using your office number
  • access your PhoneLine+ account on your computer and use the analytics to see how calls are managed and returned
  • set messages for your Voicemail and Out of Hours to better manage customer expectations
  • add a second number and have calls announced so they can be answered appropriately


Why do you need it?
The PSTN network is being turned off, so to keep your phone and your number working you need to move to the new IP network. Using IP, voice calls are delivered using the same infrastructure as data, using VoIP technology. If you already have a broadband service then it is likely that it will be able to support PhoneLine+, keeping disruption to a minimum.

£9.00 per month

  • Includes Calls to UK landline and mobile numbers
  • Includes International calls to landlines in USA, Canada, Australia, New Zealand and Eire

Minimum contract 24 months. Price per seat. Choice of IP handset devices available – prices on request.

Easy to use
The user interface is designed to be intuitive and familiar in its choice of icons, and the main functions are on the front page. Plus, there are ‘How to’ guides available online that can be accessed from within PhoneLine+.

Key features
PhoneLine+ offers all the key features of a traditional telephone line including:

  • Voicemail
