Did you know that in 2025 BT will turn off their ISDN and PSTN networks for voice calling? We asked Nick Cohen, business development manager at Time Communication Solutions, for his recommendations on how business owners can prepare for the ISDN and PSTN switch-off.
Your business telephone system might not be something you’ve given much thought to recently – or ever? There are two main services that business phones traditionally operated on - Integrated Services Digital Network (ISDN) and Public Switched Telephone Network (PSTN), more commonly known as analogue lines.
What is the ISDN and PSTN switch-off?
The communications industry is going through a huge shift right now, similar to the analogue TV switch-off that was finalised in 2012 (remember that?).
BT announced in 2015 that they will switch off their ISDN and PSTN services in 2025. The Integrated Services Digital Network (ISDN) service is a telephone-based network system that transmits voice and data over copper wires. They are used to allow businesses to make voice calls on multiple numbers, while transmitting data and conducting videoconferencing simultaneously.
PSTN systems also consist of physical copper telephone lines and are currently used by millions of homes and small businesses. They have generally been used in smaller businesses where only a single number and maybe only a few concurrent calls are required.
“The physical infrastructure has gradually become outdated and more expensive to maintain”, Nick explains. “As internet connectivity and reliability has improved, Voice over Internet Protocol (VoIP) telephony systems have increased in popularity. With BT’s announcement, all businesses will have to move over to VoIP by 2025.”
What do I need to do to prepare for the ISDN and PSTN switch-off?
While there’s certainly no need to panic, Nick’s advice is to start planning and complete your transition to VoIP as soon as possible.
“BT has said they will stop taking new orders for the ISDN service a few years prior to the switch off date, maybe even beginning as early as 2020, which has given everyone in the industry some clarity around when people will need to do something about this. As we approach the 2025 switch-off, communications businesses and number port migration departments will become increasingly busy”, Nick says.
Benefits of VoIP
Businesses that switch over to a VoIP service enjoy a number of benefits, including:
Are there any downsides to VoIP?
Nick explains that people are sometimes wary of VoIP because of poor experiences in the past.
“Ten years ago, when VoIP was a technology in its infancy, internet connections wasn’t as good. It relies entirely on internet connection, so if the infrastructure isn’t there, a different solution might be required”, Nick says.
If your area currently lacks high-speed internet connections, Nick says that a hybrid ISDN-VoIP system can be used, though the need for this is rare.
What help is available for transitioning to VoIP?
The government is making a big push for improving connectivity and have made £67m available for businesses to claim £2,500 towards the cost of installing full fibre gigabit capable connections.
The Better Broadband Voucher Scheme also provides vouchers of up to £350 for installation of basic broadband for businesses that will not benefit from superfast broadband in the next 12 months.
There are many other grant schemes available to help your business grow that you might not be aware of – some with a digital focus and others more general.
What are the main points to consider when getting a new telephone system?
“One of the first things to consider, whether you’re in a serviced office or a home office, is to get a number you’re comfortable with”, Nick advises. “Some people want to just use their mobiles, which is fine, but others who are targeting a local audience may want a local number.”
He continues: “03 numbers are also available and are counted in mobile inclusive minutes for callers to the number. It’s cheap to buy a number and then you own it.
“Sometimes business owners get caught out when they realise that their serviced offices won’t let them take their number with them when moving, so that is worth being aware of to save hassle in future if you move.”
Other than the number, the main choice for new phone systems will soon be between on-premise VoIP – for those that want the system on-site, and hosted VoIP – for those who want flexibility and off-site support with guaranteed uptime and backups. Your communications consultants will be able to advise you on packages.
