Every calling product demos well. The difference shows up on a Tuesday afternoon in the third week.
In a demo the network is fine, one person is calling, and the number being dialled has been dialled before. Nothing in that resembles fifty people working a cold list over a shared office connection.
So the demo tells you almost nothing about the thing you are actually buying, which is whether the call connects and stays up.
Ask questions the happy path cannot answer.
We run our own certification network on this platform every day, so an outage reaches us before it reaches you. That is the honest version of a reliability claim: not an uptime number in a marketing box, but the fact that we are on it too.
What we do not have is a decade of published uptime history, because the calling module is not a decade old. Anybody quoting you five nines on a young product is quoting you an aspiration.
Tell us what you need — education, study abroad, healthcare, property, technology, marketing, recruitment or outsourcing — and the right team will come back to you.
