Microsoft PSTN Calling… Have you waited long enough for it? As the preview of Microsoft PSTN Calling is currently available and its full launch is imminent, today’s blog is all about Microsoft PSTN Calling!

Back in 2015, Microsoft began to offer Cloud PBX services with PSTN Calling, which was, at the time, heralded as an ambitious step by Microsoft. They wanted to provide their users with the traditional phone calling capabilities, but without the need to manage on-premises equipment.

Since this announcement, Microsoft has significantly opened up Cloud PBX with PSTN Calling, expanding this service to over 32 countries, and allowing customers in those countries the ability to take advantage of flat-rate, per-user, per-month pricing. In January of 2018, Microsoft PSTN Calling preview reached Canada, with Microsoft’s intention being to make this generally available in the near future.

From the questions we have received from our customers, we know many organizations in Canada have anxiously waited for Microsoft PSTN Calling service to become available. In this blog, we’ll discuss what you need to know about Microsoft PSTN Calling, including what it is, who needs it, the benefits, and how you can get started.


PSTN Calling – A Brief History

The traditional Public Switched Telephone Network (PSTN) system is circuit-switched telephony – a dedicated channel (circuit) between the person making and the person receiving the call – that uses copper lines that Bell (or whatever telephone company owned the infrastructure) runs from their central hub into your home or office. Then, your Private Branch Exchange (PBX) logs the call and route it to the appropriate receiver.

Before the digitization of these calls, these PSTN systems manually connected those pieces of copper wire through a switchboard. The longer distance the call, the more copper wire was needed, and the more expensive the service was.

Over the years, technology advanced and phone calls became more digitized, allowing for the introduction of fibre optic cables, cellular networks, communications satellites, microwave transmission links, and undersea telephone cables.

This traditional way of PSTN calling was set on edge after the emergence of Voice over Internet Protocols (VoIP) around 1995, which allowed people to use the Internet to make and receive phone calls at a significantly reduced cost (in some cases, completely free). When VoIP originally emerged, it was plagued with poor sound quality and connectivity issues, but with the introduction of broadband Ethernet internet, that improved, and by the early 2000’s, companies were starting to realize how this technology could benefit them.

What is Microsoft PSTN Calling?

Microsoft PSTN Calling is now in preview in Canada, and marries the traditional PSTN Calling with VoIP technology to provide those organizations that have a traditional on-premises “landline” with a completely Cloud-hosted PSTN solution. Available through the Skype for Business Cloud PBX, Microsoft PSTN Calling can give people in your business their own, primary phone number, which they can use to make and receive calls – all through the Internet.

Simply put, with Microsoft PSTN Calling, you can ditch the cumbersome on-premise structure and move to a Cloud solution that lets you make and receive calls from your PC, handset, or mobile device – often at a significant cost reduction.
