A recent report of a Cisco VoIP phone vulnerability is very disturbing.

This is more serious than phone calls.
If the network world article is accurate, its first paragraph “vulnerability in its IP phones that allows hackers to access calls and call data” should read
“vulnerability in its IP phones that allows attackers to eavesdrop in people’s offices, boardrooms and bedrooms”
— or in fact, “continuously monitor and record all sound in people’s offices, boardrooms and bedrooms”.
