Don't let the BT switch-off stress you out. With PSTN Replacement Solutions, you can continue using your existing phone systems and future-proof your phone lines with ease!

Are you tired of worrying about the upcoming BT switch-off and the need to replace your existing phone system? Look no further than PSTN Replacement Solutions. Designed for home users and small retailers, these solutions allow you to carry on using your existing handsets and phone systems while future-proofing your phone lines for the switch-off.

So how do PSTN Replacement Solutions work? Simple! We provide customers with a router with an integrated analogue telephone adapter (ATA) or a multiport ATA and router for multi-line services. You then connect your existing handsets to these devices. We replace your phone line with a Multinet Mobile SIM that is connected to all four main mobile providers. These Multinet SIMS can only be used for our SIP Overlay service.

Our SIP Overlay service uses mobile data to make and receive VoIP calls using your existing handsets and landline number. It's that easy! And if you just want to use the SIP Overlay service with mobile handsets, you don't even need a router or ATA device. We can provision your service with a geographic landline number, and the same number can be shared with up to three mobile devices.

Our PSTN Replacement Solutions offer a range of features, including two channels, voicemail, call recording, call forwarding, DND, emergency services access, proactive network monitoring, and contact integration. They're perfect for school classroom extensions, hotels and serviced apartments, care homes, home users, shops and small retailers, lift line replacement, alarm line replacement, and fax line replacement.
