Know your phone lines answer before your customers find out they don't

PingVo places real test calls against your numbers around the clock — from a ping to the trunk all the way to hearing your IVR — and alerts you the moment callers hit silence.

// WHAT WE CHECK

Four checks, from dial tone to menu

A number that rings is not a number that works. PingVo tests the whole path a real caller takes, so a fault anywhere along it surfaces as a specific, actionable alert.

Line check

Is the trunk alive? A lightweight ping to your provider every minute or two, at no call cost, so a dead SBC is caught long before anyone dials.

Real call

Does it connect? An actual call to the actual number — the same route your customers take — confirming it is answered rather than rejected or lost in routing.

Audio

Is there sound, or dead air? We listen to what comes back and catch the failures that look fine on paper: silence after answer, and one-way audio.

IVR check

Right menu, right greeting? We match the prompt that plays against the one you approved, so a wrong or stale recording does not run for weeks unnoticed.

IVRs, auto-attendants, conference bridges, hotlines — if it answers by itself, PingVo can test it.

// WHY TEST CALLS

Zero calls at 3 a.m. proves nothing

Call reports are passive. They show the calls your customers managed to make — never the ones that never connected.

When traffic is low — nights, weekends, public holidays — a quiet line and a dead line look exactly the same on a dashboard. PingVo places its own calls on a fixed cadence around the clock, so a quiet hour is checked exactly like the morning rush. A change that breaks your lines on Friday evening reaches you on Friday evening, not from your first caller on Monday.

// WHO IT IS FOR

Built for the people who get the angry call

Ops and support teams

Your support line, your sales number, your out-of-hours queue. When a carrier changes something at 3am or an IVR update goes out with the wrong recording, you find out from PingVo rather than from a customer who could not reach you.

Every alert says which number failed, at what stage, and whether the fault looks like your PBX, the carrier, or the route in between — so the first ten minutes go to fixing it instead of narrowing it down.

MSPs and telecom resellers

Every client's numbers in one account, grouped per client, with each group's alerts routed to the people who should get them — your NOC, the client's own helpdesk, or both.

Pricing is per number, so what you pay tracks your book of business, and catching a client's dead line before they notice is the kind of thing that renews contracts.

// WHEN SOMETHING BREAKS

Alerts you can act on, not a wall of noise

A single odd result never pages anyone — PingVo re-tests to confirm before opening an incident. What lands is one alert per fault, naming the number, the stage that failed and the likely cause: your side, the carrier, or the route in between. Failed calls keep a short recording so you can hear it yourself. Email on every plan; signed webhooks and a metrics endpoint on Pro, so incidents reach the tools you already use.
