MIGRATING FROM ISDN/PSTN TO SIP OR VoIP

BT Announced in 2015 that it will be switching off its PSTN and ISDN networks in 2025, transitioning fully to IP Voice services and phasing out older networks from 2020. This means that BT will cease accepting ISDN orders and that any businesses looking for new or increased voice services will have to look at IP-based options for their Business Telephony Systems.

Recent surveys suggest that many businesses are still not aware of the impending switch-off and the affects that it may have on their business communications. If your business uses either PSTN or ISDN, we recommend looking into how you can migrate your own system onto an IP service.

Fear not, there is a great deal of positivity. Firstly, using IP and Cloud Telephony has significant cost benefits, reducing or eradicating line and call costs. Provisioning is much quicker and more easily controllable and service can be accessed from anywhere on multiple devices, making your business more agile and responsive. And there are a plethora of new features and functions available.

PSTN/ISDN IN BRIEF:

PSTN (Public Switched Telephone Network) is where analogue voice data travels across copper-based circuit-switched phone lines.

ISDN (Integrated Services Digital Network) offers voice and data over digital lines offering further services such as DDIs (direct dial in numbers) and Video Conferencing. And allows for multiple calls on different channels over the same line.

WHY THE SWITCH:

PSTN and ISDN are legacy technologies that have been significantly upgraded over their life-time but have high maintenance and running costs. BT is looking to switch to a single IP Network, allowing for SIP and VoIP, which offer multiple benefits to businesses. Investment in PSTN and ISDN networks is ceasing while there is ongoing investment in the IP Network.

SIP/VoIP IN BRIEF:

SIP (Session Initiation Protocol) provides a phone line over a fibre internet connection.

VoIP is cloud based telephony whereby your phone calls are sent over your internet connection and your phone system is moved ‘online’. You can access your system via multiple devices – deskphone, mobile and tablet and it offers many additional features such as call recording, voicemail to email and unified communication benefits.

Clarion Communication ManagementWHAT YOU NEED TO CONSIDER:

Find out your current contractual obligations and think very carefully before renewing any ISDN or PSTN contracts.

Look at the options available. Many newer Phone Systems support IP Telephony. If yours doesn’t, you will need to replace the system with a VoIP system or an IP-enabled on-premise PBX (phone system)

When switching to SIP/VoIP based systems, you will need to make sure that you have sufficient bandwidth to deliver voice on top of the existing services that your office data line supports, otherwise you may experience poor voice quality or intermittent service.

KEY BENEFITS OF SIP AND VoIP:

  • Massive Savings –  removal of line rental charges, free UK Landline and Mobile calls and between your organisation’s sites and much reduced Intl charges.
  • Flexible Working – Log into your Phone System from anywhere and any device with an internet connection, and take your number with you.
