Telephony should belong to the business, not to the PBX vendor

We build a cloud PBX that doesn’t take your numbers away and doesn’t profit from your traffic. The telecom contract and its rates stay yours; our job is the smart layer on top — call flows, recordings, oversight. It’s cheaper for the customer and a more honest business model.

01

We don’t profit from traffic

No markup on minutes, no number rental, no bundles. The only line on the invoice is seats. Our incentives match the customer’s.

02

Openness instead of lock-in

Any SIP carrier, export of recordings to your own storage, call-event webhooks. Leaving us is technically easy — so we keep customers with quality rather than a lock.

03

Data in your jurisdiction

Voice runs through your region’s server and recordings stay there too. Russia for Russian customers, Singapore for South-East Asia.

How our business model works

A typical cloud PBX earns on traffic: it resells numbers, marks up minutes, sells bundles. The more the customer calls, the more they pay — and the less reason the vendor has to help them call less. We are built the other way round, and it is worth saying plainly, because it decides who we suit.

We are not a carrier and do not want to be

Numbers, minutes and the telecom contract sit between you and your carrier. We do not insert ourselves into that chain: no reselling traffic, no invoicing calls, no holding numbers hostage. If you already have a carrier you are happy with — good, we work on top of them.

One line on the invoice: seats

You pay for the people who need a phone. The team doubled its calling and our invoice did not move. That makes costs predictable and removes the conflict of interest: we gain nothing by nudging you towards more minutes.

Leaving us is technically easy

Recordings export to your storage, call events go out over webhooks, the numbers were yours all along. We deliberately do not build a lock: a vendor you cannot leave eventually stops trying. Keeping customers on quality is both more honest and better for us.

Data stays in your jurisdiction

Voice runs through the server of the region you pick, and recordings and history live there too. Russia for Russian customers, Singapore for South-East Asia. The region is chosen at onboarding and is never moved without your knowledge.

Questions about the company and terms

Who is sipbox not a good fit for?

Anyone who wants numbers and a PBX as a single package from a single vendor. Our model assumes telecom is yours: either you already have a carrier or you are willing to connect one. If you want a phone system handed over with no involvement, a carrier’s own PBX is simpler — one invoice, though more expensive at volume.

What happens if we decide to leave?

The numbers stay with you — they are on the carrier contract, not on us. Recordings export to your own storage. There is no exit procedure: you stop paying for seats and take your data. We write no lock-in clauses into the agreement.

Where are call recordings physically stored?

In the region chosen at onboarding: Russia or Singapore. Recordings can also be exported to your own storage, so a copy lives wherever you decided. That is a standard setting, not a separate service.

How stable are you as a vendor?

We are a young company and will not pretend otherwise. That is exactly why the model minimises dependence on us: your numbers, your carrier, exportable data. The cost of switching vendors here is markedly lower than with a carrier’s PBX, where the numbers leave together with the PBX.

Do you have customer case studies?

No published cases with company names and figures: not enough customers have given written consent yet. We will not invent them. Instead the site has a “Use cases” section, which honestly describes typical platform setups rather than the stories of particular customers.
