VoIP decision guide · Canada · EN / FR

Price the outage before you price the phone system.

Ce guide est aussi tenu en français. Décisions VoIP →

A VoIP proposal is usually compared against the current phone bill. The more useful comparison is what a connectivity or provider outage would actually cost the organization, and what the current system already survives that a new one needs to match.

The decision to enable

Decide whether to move to VoIP, what it depends on to keep working, and what an outage of the new system would actually cost—before comparing monthly prices.

Confirm what the current system already survives

A traditional phone line often keeps working during a power or internet outage in ways a VoIP system will not unless that is specifically designed in. Name what the business currently relies on the phone system to do during a disruption before assuming a like-for-like replacement.

Make the network dependency explicit

VoIP call quality is a direct function of the network guide’s own criteria: bandwidth, latency, and a properly configured, prioritized connection. A VoIP migration approved without confirming the network first inherits every unresolved network problem as a phone-quality complaint.

Separate the monthly rate from the full switching cost

Porting existing numbers, replacing handsets, training staff on a new system, and running two systems in parallel during cutover rarely appear in the advertised per-line price. Price the full transition before comparing the ongoing monthly figure to the current bill.

Confirm the exit path before signing the contract

Ask what happens to call history, voicemail, auto-attendant configuration, and the phone numbers themselves if the organization needs to change providers later. A system that is easy to enter and hard to leave shifts real risk onto the buyer.

Decision frame

What leadership should be able to verify.

These criteria do not produce a score. They expose the questions that need resolution before a responsible decision.

Practical scenarios

The same discipline applied to different decisions.

A provider quotes a low per-line rate that excludes hardware and porting

Situation: A VoIP proposal’s headline price looks well below the current phone bill, but handsets, number porting, and setup are quoted separately.

Useful response: Build the full first-year cost including hardware, porting, training, and any parallel-running period, and compare that total—not the bare per-line rate—to the current arrangement.

Boundary: This guide does not evaluate a specific VoIP vendor or guarantee call quality on any given network.

A weather event knocks out power and internet for several hours

Situation: Leadership discovers during an actual outage that the new VoIP system has no way to receive or redirect calls without power and internet.

Useful response: Decide this continuity requirement in advance—call forwarding to mobile numbers, a battery-backed router, or an accepted gap—rather than discovering the answer during the next outage.

Boundary: This guide does not design a specific business continuity or power backup solution.
