What can IT leaders replace PSTN & ISDN with?
Read on to understand how you can embrace this digital future
TalkTalk Business offers VoIP voice services, also called Digital Voice as an alternative to the traditional PSTN. As Digital Voice is Internet Protocol (IP)-based, it works over the broadband connection. VoIP phones must plug into your router/broadband hub or via an adapter.
Digital Voice services offers more features and can be used from more device types than just a telephone. They can integrate with your other IT systems, and enable greater collaboration to your teams, enhancing productivity and time. As well as voice calls, Digital Voice gives you a feature-rich solutions that can be tailored to you and grow with your evolving needs, future-proofing your telephony needs.
To be able to use Digital Voice, you’d need to have one of the following new Openreach line types: SOGEA, SOGFast or FTTP.

If you’re not ready to move to Digital Voice, our customers can still prepare for the 2027 Switch Off with Metallic Path Facility (MPF).
Unlike other providers, TalkTalk Business offers voice services via MPF. This technology utilises the existing copper wires, connecting directly from our equipment in the BT Telephony exchanges to our customers’ premises. This ensures a smooth connection for standard (i.e. non-VoIP-compatible) phones to our own telephony switches.
TalkTalk Business's MPF voice services are therefore unaffected by WLR stop-sell or withdrawal in 2025, which means that we can continue to offer broadband and Fibre to the Cabinet (FTTC) with MPF. MPF FTTC is functionally identical to SOGEA in respect of broadband performance and availability.
MPF is a seamless solution that puts control back in your hands, giving you more time to plan and implement your digital strategy to move onto Digital Voice, when you’re ready. We're proud to be offering this flexibility to the public sector.
Yes, very useful!

Not particularly
TalkTalk Business currently have equipment in 3000+ Openreach exchanges across the UK, which equates to 92% national coverage where customers can or are using MPF.
Where we don't have exchange presence, in the immediate-term, customers can remain on their existing WLR connections till December 2025 from which point they will need Digital Voice options for telephony. TalkTalk Business also offer IP-based telephony options including SIP (Session Initiation Protocol) and hosted voice, Digital Voice solutions.
We're working hard to ensure that all our customers have alternative connectivity solutions available and will continue to share updates as our coverage increases further.
Our MPF voice services are unaffected by the Switch Off, allowing us to continue offering broadband and Fibre to the Cabinet with MPF. This gives you control, providing more time to plan a move to Digital Voice. We are making it our mission to help and work hand in hand with the public sector.
