ISDN Switch-off

ISDN lines are still used in most industries, including the finance industry however, like most industries you need to start looking at alternative solutions because of the BT ISDN Switch-off.

ISDN Phone lines are being phased out; from September 2023, BT will withdraw the ability to purchase any additional ISDN lines. Between April and December 2025, there will be a forced migration period before they switch them off.

Essentially, you have time to consider and budget accordingly for your alternative solution but it is inevitable; you need an alternative phone line solution.

Alternative Phone Line Options for your Finance Company

A direct replacement to ISDN phone lines would be SIP Trunks or Phone Line + but if you are considering your phone system options at the same time; different phone systems can replace the need for SIP Trunks.

You could potentially keep your ISDN phone lines and purchase the additional lines that you think you may need to carry you through for the next few years and switch to one of the other options at a later date. This would give you some time to plan and budget accordingly.


Phone Line + replaces traditional landlines using VoIP technology to deliver voice calls over the broadband network.

Phone Line + is an easy-to-use software-based solution which is updated and maintained remotely. You’d have complete control over users; easily adding/removing users, allocating your phone numbers and changing privacy settings such as including any numbers that you want to block.

With Phone Line +, you’ll be able to:

  • Access from any Device
  • Manage more than one number
  • Use Key Features such as Voicemail, Call Divert, Call Hold, Contact Directory, Call Transfer, Call Forwarding and Number Withholding.
  • Set an Out of Hours profile 
  • Store business essential phone numbers
  • Receive email notifications of missed calls and voicemails
  • Access Call Analytics 

SIP Trunks (SIP Lines)

SIP and SIP trunks is an on-premise or hosted solution for a telephone system that will use virtual phone lines rather than physical wires.

SIP Trunking is fast becoming the best alternative to ISDN as it is cheaper on a per line basis, it offers flexibility and control over your phone numbers and quicker to install.

Any finance company with a compatible PBX can switch to SIP trunking service and immediately benefit from more flexible, less expensive and more resilient phone service.

Our top five benefits for upgrading your finance company to SIP:

  • Save Money on call costs and line rental – IP connectivity costs less than ISDN so you’ll benefit from lower call costs; free internal calls between sites and free calls to UK local/national and mobiles. Typically, you are looking for saving of up to 50% on line rental and 25% or more on call costs.
  • Flexibility with phone numbers – SIP trunking enables you to reduce the number of PBX’s you need to maintain whilst maintaining your existing phone number(s).
  • Scalability – You are always in control because you can add lines, remove lines and split calls at any time.
  • High Quality – We can proactively monitor and manage the quality of service across the entire network – it’s the underlying network quality that makes a real difference to SIP trunking. 
  • Business Continuity – SIP trunking allows you to take your phone lines with you quickly and cost-effectively should a disaster strike.

Hosted Phone System

The Hosted Phone system is cloud-based which means you connect to it using an internet connection (IP technology) but effectively you are renting the system rather than purchasing your own dedicated system.

A Hosted Phone system is a low-cost alternative to other phone systems because you don’t have significant upfront capital costs and its usually a pay-per-seat cost model.

IP Phone System

An IP Phone System uses Internet Protocol (IP) technology and the handsets are connected via an Ethernet connection either on a Local Area Network (LAN) or a Wide Area Network (WAN.)

When you choose an IP Phone System, you purchase the phone system for your own use and you choose where to host it. It gives your finance company more ownership over the use of your phone system but you’ll need to account for more of the time element in maintenance.
