DIGI-VOICE | Digital Upgrade for PSTN Phone Lines

DIGI-VOICE is an all-in-one solution to upgrade mission-critical phone line communications from analogue (PSTN) to digital (CLOUD).

DIGI-VOICE maintains full compliance on emergency lift phone installations after the PSTN fixed phone line infrastructure is retired. 

The DIGI-VOICE routes voice calls using any data connection ie: LAN, WiFI or SIM card. The calls are then delivered via Cloud SIP service with an impressive array of visibility, analysis and monitoring features compared to landline or GSM.


An ideal and very simple retrofit solution designed to resolve issues associated with the BT fixed line switch off in 2025.

DIGI-VOICE requires no configuration whatsoever. It is provided ready to dial out and dial in using an included UK local 01/02 phone number. Power on and the dial tone will be present after approximately 30 seconds.

It couldn’t be easier to replace a landline and at a fraction of the annual running cost. Upgrade any landline system in less than 1 hour!

For applications such as emergency lift phones, it is highly recommended to adhere to the requirements of BS EN81-28 for remote communications. The DIGI-VOICE device complies with and exceeds all EN81-28 standards including remote dial-in, battery back up for 8 hours and up to 4 hours talk time.
