PSTN switch off FAQs
Unsure how it will affect you when the Public Switched Telephone Network (PSTN) is fully retired in 2027? You’ve come to the right place. These FAQs cover the key things to know about the PSTN switch off, including when and why it is happening, along with the best ways to prepare.
Please note that specific details, including timelines and available options, may vary depending on your location and service provider.
8 common questions about the PSTN switch off
Why is the PSTN being switched off?
The PSTN is being switched off primarily because it uses outdated technology that relies on deteriorating copper phone lines.
As the old cables are becoming costly to maintain, and newer technologies offer more advanced features, the PSTN no longer offers the best options for phone and internet connection.
Instead, newer digital communication technologies like VoIP and mobile phone networks are being prioritised as they offer better scalability and cost efficiency for both network operators and end users.
When is the PSTN switch off?
The PSTN lines will be completely retired on 31 January 2027. If you still rely on traditional copper wires for your phone or broadband connection, you will need to switch before 2027 to avoid disruptions.
Will the ISDN be affected?
As the Integrated Services Digital Network (ISDN) relies on the PSTN, this too will be switched off on 31 January 2027.
If you currently use the ISDN for any technologies, such as for voice or video calls, you will need to switch to an alternative like VoIP.
What are my options to switch?
Several good PSTN alternatives are available. A particularly popular option is VoIP technology which transmits voice calls over the internet.
Other options include mobile networks with cellular-based digital voice services, and unified communications (UC) platforms that integrate various communication channels into a single system.
Will I save money by switching phone lines?
In the long term, switching from PSTN to VoIP or other digital communication technologies should be cost-effective.
While there might be some initial investment in upgrading infrastructure and equipment, the operational costs are typically lower for digital voice systems.
How long does it take to switch to VoIP?
The time required to transition from PSTN to VoIP depends on various factors, including:
- The complexity of the existing infrastructure
- The size of the organisation
- The chosen implementation strategy
However, it can potentially take just a couple of weeks for the entire process, including the planning, equipment installation, network configuration and user training.
What will happen if I delay switching?
If you delay switching from PSTN connections, you may face issues with your phone and internet service.
As the PSTN is phased out, service providers will gradually reduce support for and quality of analogue phone systems.
Switching sooner rather than later ensures your business is protected from disruption.
Do VoIP packages include devices?
When switching to VoIP, check whether the package deal includes handsets and related equipment. This will depend on the service provider and the chosen deployment model.
In some cases, service providers might offer hardware as part of their service package, while others could require you to purchase or lease the equipment separately.
