[Linphone-users] hardware with secure key for linphone

[Louis Holbrook]

I was looking into getting a hardware SIP phone today, but couldn't find
any alternatives which tell me that key is not potentially compromised
with a back door somehow.

Putting linphone on an Android kind of suffers the same fate, with
google ultimately controlling the bottom layer.

So I'd like to ask: Are there any certified (open) hardware solutions to
put linphone on, where I can have a greater guarantee that key integrity
is kept and no (deliberate by design) backdoors are implemented?

Thanks.
