As you may be aware, BT is retiring its public switched telephone network (PSTN) by December 2025. Other providers that use BT’s network and other companies with their own networks will follow a similar timescale.
In addition, telecoms providers are also investing in new systems and networks. They will need to switch customers away from the old PSTN at the same time as upgrading their technology. This means that in the future, landline calls will be delivered over digital technology, called Voice over Internet Protocol (VoIP).
Like residential customers, small businesses that want to continue using their landlines will eventually have to move to VoIP services. Equipment such as card payment machines, alarms, and monitoring equipment connected to landlines may also be impacted. Businesses will need to contact their landline provider and equipment suppliers for specific advice. Click here for more information
