As Openreach’s plans to switch off PSTN and ISDN services by December 2025 loom closer, businesses and customers will need to transition to a fully digital alternative. The two main alternatives to consider are VoIP and SIP, which offer several benefits over traditional telephony systems.
Switch to VoIP
VoIP, or Voice over Internet Protocol, allows calls to be made over a data network, such as the internet, instead of a landline. This provides benefits such as higher call quality, smaller and more manageable bills, and scalability. VoIP is a great option for small to medium-sized enterprises that need a flexible system to keep up with their growing business.
Upgrade to SIP
SIP, or Session Initiation Protocol, facilitates the connection of private phone systems to a public telephony network, such as the internet. This approach preserves many of the current features, numbers, and call quality of legacy telephone systems while adding the benefits of a hosted voice solution. Larger enterprises with longstanding legacy telephone systems or operators of essential services might find SIP to be a better fit.

Which solution is right for me?
When choosing the right solution, it is critical to consider factors such as whether retaining a private phone system (known as a Private Branch Exchange) is important and if the business is restricted by specific considerations. Partnering with a technology provider can help advise and guide you through the many connectivity solutions available.
Opus work with businesses to understand their current setup, how they operate, and their future strategy to recommend the best course of action that meets the demands of your business and allows for scalability. Being prepared and working with a provider who understands where a business wants to go is essential in preparing for The Big Switch Off in 2025.
