Calculators

Put numbers on the messy mornings

Two estimates, using your fleet size. They are models, not promises — useful in a QBR or when you are deciding whether monitoring is cheaper than another Friday of console-hopping.

Time saved

How much tech time you spend just checking that each 3CX is “fine”, versus glancing at one fleet board.

Default assumes eight minutes a week per box (a login, a glance, a note) down to about a minute on a fleet view. Adjust to how your shop actually works.

If 3CX goes offline

Cost of an outage that stays silent until someone notices — overnight trunk death, missed detection, morning pile-on.

Six hours is a 2am failure found at 8am. Fifteen minutes is “alert fired, someone looked”. This is staff time / margin only — it does not add brand damage or missed emergency calls.

Kestrel is the board and the alert, not a guarantee of zero downtime

We poll and we page. 3CX, the network, and the person who answers still have to do their jobs. Pricing is per PBX so you can line it up against the numbers above.
