Hello, I would like to suggest 3rd party/ Customer managed device support for the Engenius DuraFon SIP Phone System. This cordless phone system operates on the 902-928 MHz range which works really well in the use cases that require broad wireless coverage in large industrial facilies such as a warehouse spanning several acres beyond the range of wifi and DECT cordless based systems. The manufacturer has confirmed support for TLS 1.2/SRTP and already has certified support with Broadsoft, OnSIP, RingCentral and Nextiva UCaaS platforms.
