What Is Cloud PBX and Why Are Businesses Switching?
Cloud PBX, also called hosted PBX, is a business phone system run from a provider’s data centre. A PBX (private branch exchange) routes calls inside a business: extensions, transfers, voicemail, hold queues and the greeting callers hear first. It used to mean hardware in a back room; with cloud PBX, the provider runs and updates it.
Phone systems are following a wider move to cloud services. In Statistics Canada’s most recent survey of business technology use, 48% of Canadian businesses with five or more employees used cloud computing in 2023, the most commonly used technology the survey tracked (Statistics Canada). Where people work matters too. Even as commuting has picked up, 17.4% of employed Canadians worked mostly from home in May 2025, and 10.0% usually worked both at home and outside the home (Statistics Canada). For hybrid and remote teams, a phone system tied to one office desk is a poor fit.
How Does a Cloud Phone System Work?
The Path of a Single Call
Picture a customer dialling your main number. The provider’s platform plays your greeting, the caller presses 2 for service, and the system rings the right extensions wherever those people are: a desk in Burlington, a home office in Hamilton or a mobile app at a job site.

What Your Office Needs
Getting started requires hardware and/or software. Some teams use IP desk phones; others use softphone apps on laptops and smartphones. Our guide to hosted PBX hardware requirements covers the options in detail.
The internet connection matters more than most people expect. Each call typically uses about 25 to 80 Kb/s in each direction, depending on the codec. That is modest per call, but it multiplies with every call running at once, and a stable connection matters as much as raw speed. Quality of Service (QoS) settings on your router tell the network to give voice traffic priority over large downloads. Under ITU-T G.114, the international standard for call delay, one-way delay below 150 milliseconds keeps most conversations natural (ITU-T G.114). For sizing advice, see how much internet speed a business VoIP phone system needs.
Which Cloud PBX Features Matter Most for Small Businesses?
The features that change day-to-day work:
- Auto attendant (IVR). A professional greeting that routes callers through a dial-pad menu to the right person or department, without a full-time receptionist.
- Find Me / Follow Me and mobile apps. Calls to your business number ring on your desk phone, then your smartphone, so customers reach a person instead of voicemail.
- Voicemail to email with transcription. Messages arrive in your inbox as text you can scan quickly.
- Call queuing and hunt groups. Callers wait in line while calls spread across the team.
- Call recording. Useful for training, quality reviews and checking what was agreed on a call.
- CRM and Office 365 contacts integration. Caller details appear before you answer.
On Intratel’s Hosted PBX, these features are configured to your call flow rather than sold as a fixed package. Which features you get depends on your Intratel plan.
What Are the Benefits of Hosted PBX for Canadian Businesses?
How Does Cloud PBX Lower Phone Costs?
In one Intratel case, consolidation made the biggest difference. Kodarin Industries and BlueSky Process Solutions, two industrial companies sharing office space, were running separate phone systems with separate bills. After moving to one Intratel system, they cut their monthly telephone costs by at least 50%. Your savings depend on what you pay today.
How Does Cloud PBX Help a Growing Business?
Adding an employee means adding an extension, not a new phone line or a hardware upgrade. Opening a second location works the same way, with every site on one system. Spectrum Patient Services, a healthcare organization going through an expansion, reduced the long-distance charges it was paying for calls between its own offices after moving to Intratel.
What Happens to Cloud PBX During an Office Outage?
Because cloud PBX lives in the provider’s data centre, a power cut or internet outage at your office does not stop your number from answering. Desk phones in the building go quiet, but with emergency forwarding set up, calls ring through to a backup mobile phone. Our post on what happens to your business phone system if the internet goes down walks through the scenarios.
Why Does a Canadian Network Matter?
When you compare providers, ask where your calls, voicemails and recordings are handled. Intratel partners exclusively and directly with 100% Canadian data centres and carriers, so your calls and data stay in Canada, and the support team you reach is Canadian too.

Is Cloud PBX Right for Your Business?
Cloud PBX is a strong fit for small and medium-sized businesses, especially those with staff who work remotely or on the road, more than one location, or a phone bill that keeps climbing.
On-premise PBX is a specialist option for large businesses and call centres that want to own and run their own hardware. For most teams, Hosted PBX is the simpler, more flexible choice.
Switching is less disruptive than many owners fear. In most cases, you can keep your existing business phone number when switching to Intratel. Ask about porting and any applicable fees before cancelling your current service. Professional VoIP setup and integration keeps the cutover smooth.
