The short answer
Your phone system currently lives in a box on a wall. Cloud phone service moves that box to a data centre you do not own, and delivers calls over your internet connection instead of copper lines.
The word VoIP just means Voice over Internet Protocol — your voice travels the same way your email does. UCaaS is the industry’s word for the packaged version: calling, texting, video and voicemail bought as one monthly subscription per person.
What actually changes
Nothing on your wall
No card to replace when it fails, no vendor to outlive. The system updates on the provider’s side.
Your number follows people
The same extension rings a desk phone, a laptop and a cell phone. Staff can work from the office, a truck or home without handing out a personal number.
You pay per person, per month
Not a capital purchase you amortise over ten years and then nurse for another five.
Adding someone takes minutes
Not a service call and a card order.
What does not change: your phone number. Porting moves it as-is, and done properly your main line never stops ringing.
What has to be true for it to work
This is where most sales conversations skip ahead, and it is the part that decides whether your cutover goes well.
Enough bandwidth, but less than you think
A call uses roughly 100 Kbps each way. Twenty simultaneous calls is about 2 Mbps. Almost any business connection handles that. Bandwidth is rarely the problem.
A network that prioritises voice
This is the real issue. Voice is unforgiving about timing — a video stream can buffer, a phone call cannot. If someone starts a large upload and your calls go choppy, that is not a bandwidth problem, it is a prioritisation problem, and it is fixable.
PoE on your switches
Desk phones draw power over the same cable that carries data. If your switch does not supply it, you need injectors or a different switch.
Cabling that can carry it
Cat5e or better. Cat5 from 2004 will often work and sometimes will not, and you want to know which before cutover day, not after.
The devices everyone forgets
This is the list that turns a smooth cutover into a bad week. Before anyone quotes you, someone should physically walk your building and count:
- Fax machines and the lines they sit on
- Overhead paging and door intercoms
- Elevator emergency phones — these are life-safety and legally required to work
- Alarm panel dialers
- Credit card terminals on analog ports
- Modems on lines nobody remembers ordering
Some carry over with an analog adapter. Some need a different answer entirely. Either way you want it in the quote, not in a change order.
What it costs
Service runs per user, per month, from the provider. Longer terms and larger headcounts bring the per-seat price down, which is why any honest quote starts with a headcount question.
Installation is separate and one-time: the account build, number porting, call flow design, handsets and training. You should see both numbers before you sign anything.
Hardware is optional. If your team works from laptops and cell phones, you may not need desk phones at all.
When you should not move
Worth saying plainly, because most people selling this will not.
- If your internet has a single connection with no failover and your business stops when phones stop — a medical practice, a dispatch operation — fix the connection first, or plan for cellular failover as part of the project.
- If you are mid-contract with real termination fees, the maths may say wait. We will tell you the date to revisit.
- If you are a two-person office with one line that works fine, you may not need any of this.
Where it usually goes wrong
Nobody inventoried the analog devices
Covered above. It is the single most common cause of a bad cutover.
Porting was treated as an afterthought
Number porting depends on the carrier you are leaving, and they are not in a hurry. It gets scheduled, not wished for.
The call flow was copied from a template
How your calls get answered is specific to your business. A default auto attendant will annoy your customers within a week.
Nobody trained the staff
The system works fine and everyone hates it, because the person who answers the phone all day was handed a link to a help article.
