VoIP Security in a Time of War
“You cannot choose your battlefield,God does that for you;But you can plant a standardWhere a standard never flew” Nathalia Crane Just when the stress of the pandemic was starting to ease and it looked as if the world might return to some sense of normal, we suddenly find ourselves on the cusp of World War […]

Thinking Holistically about SIP Security
Every so often I am asked to write an article for a blog other than my own. I usually respond with “no.” There are only so many hours in the day and those few are already over-scheduled without taking on additional work. However, I said “yes” to this one. After all these years, I still […]
