“With over 60 of our sites having EnGenius DECT handsets connected to our analogue emergency call systems, and the news that this product had become obsolete, Housing 21 needed to ensure sufficient maintenance spares availability to cover over 90 EnGenius devices. We had to be sure that any investment in DECT technology to free up these spares, would be protected by ensuring the equipment was compatible with our future digital installations.”

David Mayes, Property Improvement Manager at Housing 21
