Is it safe to use on my home network? I don't care about encryption of calls or the like. I'm just worried that it might provide an entry point for a hacker.

Is there any up-to-date firmware available?

My network is thus:
The phone is attached to an unmanaged switch which also has a home PC (cable connection) a work-provided thin client (cable connection), and a wireless access point attached (mobile phones access the network via this). The switch is connected by cable to a home router which is a DHCP server. The phone is set to get IP address by DHCP. The network addresses in use are unrouteable (192.168.x.x). Service provider is Sipgate.

Any opinions or comment most welcome.

Most legacy phone systems can only support a specific number of phones; expanding beyond that limit requires purchasing additional hardware. Aging phones can also compromise security. Once vendors stop providing patches, updates and bug fixes, you'll face elevated cybersecurity risks and potential compliance issues
