Is VoIP reliable for business?
Yes — with one honest caveat: VoIP is exactly as reliable as the internet connection underneath it, and it is your job (with your provider's help) to make that connection boring.
The numbers are less demanding than people expect. A single voice call needs about 100 Kbps in each direction, so even a modest broadband line carries several simultaneous calls without noticing. What matters is not raw speed but consistency — jitter and packet loss are what make a call sound choppy, not a low megabit number.
What genuinely improves reliability, in order of effect:
- Wire the phones, or use good Wi-Fi. Most "VoIP is unreliable" complaints trace back to congested Wi-Fi, not the service.
- Turn on QoS on your router so voice packets go first when someone starts a large download.
- Set failover rules. This is the important one, and it is included on every plan here.
What happens to my calls if the internet goes down?
Nothing that a customer notices, if it is set up properly. When your connection drops, calls follow the rules you defined in advance — ring your mobile, roll to another team member, go to voicemail, or hand off to an AI receptionist that answers and takes the details.
This is worth dwelling on, because it is where VoIP quietly beats copper. If a traditional landline goes down, the caller hears a dead line and you find out later. With call routing, an outage becomes a redirect: the call still lands somewhere, and you still get the customer. Failover routing is standard on all our plans — $6.95/mo, $14/user/mo and $24.95/user/mo alike — not an enterprise upgrade.
Are VoIP phones secure?
Yes, and the honest framing is this: the technology is secure, and the realistic risk to a small business is account security rather than someone intercepting your calls.
What protects the calls themselves: voice traffic is carried over encrypted connections, so casual interception is not a practical attack on a properly configured service. Outbound calls are STIR/SHAKEN signed, which is the industry framework that lets the receiving network verify the call really came from who it claims — the same system that helps your calls avoid being flagged as spam.
What actually goes wrong in the real world: toll fraud. Somebody guesses or phishes a weak account password, enables international dialling, and runs up charges overnight. It is unglamorous and it is the main thing worth defending against.
How to prevent it — and all of this is included, not sold separately:
- Strong, unique passwords on the account and every extension.
- International dialling switched off unless you actually need it.
- Sensible call restrictions and spend limits by default.
- User permissions so not everyone can change routing.
- Call recording and logs, so anything odd is visible quickly.
Our support team will walk through these settings with you on setup. If you handle medical, legal or financial calls, HIPAA-capable handling is available too.
Is VoIP a landline?
No. A landline carries your voice as an electrical signal over copper wires owned by the phone company. VoIP converts your voice into data and sends it over the internet.
To the person calling you there is no difference — same number, same ring, same conversation. The differences are all on your side:
| Traditional landline | VoIP | |
|---|---|---|
| Typical cost | ~$50–$100 per line/mo | From $6.95/mo; $14/user/mo unlimited |
| Works during a power cut | Often yes, on its own line power | Calls reroute to mobile automatically |
| Works during an internet outage | Yes | Calls reroute to mobile automatically |
| Take it with you | No — tied to the building | Yes — anywhere with internet |
| Auto attendant, recording, IVR | Extra equipment | Included on every plan |
| Adding a line | Engineer visit | A few clicks |
| Long-term availability | Being retired by carriers | The current standard |
That copper retirement matters for planning. Carriers are actively withdrawing traditional POTS service, so "our landline still works" is a position with an expiry date rather than a strategy.
How do I dial 911 from VoIP?
You dial 911, exactly as you always have. The part that is different — and genuinely important — is location.
A landline is tied to a building, so emergency services know where it is. A VoIP number can be used anywhere, so the system needs to be told where the phone physically is. That is what the registered emergency address on your account is for: when you dial 911, that address is what dispatchers receive.
Three things to do, and they take a few minutes:
- Register your correct physical address when you set up service — the actual street address where the phone is used, not a billing address or a PO box.
- Update it whenever you move, including a move to a different office, a new home-working address, or a second location.
- Tell your team that if they call 911 from a mobile app while away from the registered address, they should state their actual location out loud immediately.
How do I test 911 on VoIP?
Do not simply dial 911 to see what happens — that ties up a real emergency line. There are two proper ways to check:
- Verify the registered address in your account and confirm it is the exact physical address where the phone is used. This is the check that actually matters, because it is the data dispatchers receive.
- Ask us to run a verification. Contact support and we will confirm the address on file is correctly provisioned for emergency routing. If your area operates a non-emergency test line, we will tell you.
If you must speak to a dispatcher to confirm a setup, use your local non-emergency number and explain that you are verifying a new phone system — never 911 itself.
Why use VoIP for business?
Five reasons that hold up once the novelty wears off:
- Cost. Ten landlines at ~$75 is about $9,000 a year. Ten VoIP users at $14 is $1,680. The saving is not marginal.
- Features included rather than bolted on. Auto attendant, voicemail-to-email, call recording, IVR and SMS come with every plan here, including the $6.95 one.
- It goes where you go. The same business number rings on a desk phone, a laptop and a mobile, so a van, a home office and a shop are all just extensions.
- It scales in minutes. Adding a seasonal team member is a setting, not an engineer visit.
- Calls become data. Recordings, transcripts, missed-call reports and CRM notes turn the phone into something you can actually manage.
What are the downsides of VoIP?
Three, stated plainly, each with what to do about it:
- It depends on your internet. Fix: failover rules to a mobile, and QoS on the router. An outage becomes a redirect rather than a dead line.
- Power cuts take out your router. Fix: calls forward to mobiles automatically, and a small UPS keeps the router alive if you want desk phones working through short outages.
- 911 needs an accurate registered address. Fix: set it correctly at signup and update it when you move — covered above.
None of these is a reason to stay on copper. They are three settings to get right, and we set them up with you.
How do I use VoIP?
- Get a number — a new toll-free or local number, or port the one you have ($0 either way).
- Choose how you'll talk — the mobile app, the desktop app, a desk phone, or simply forwarding to the phone you already carry.
- Set your rules — who rings first, what happens after hours, where calls go if the internet drops.
- Register your 911 address.
- Start taking calls — a new number is usually live within minutes.
The short version
VoIP is reliable when your internet is stable, and safe when your account is — and both are things you can control in an afternoon. Call quality on a decent connection matches or beats copper, an outage becomes an automatic redirect rather than a dead line, calls are carried encrypted with STIR/SHAKEN signing, and 911 works as long as your registered address is accurate.
Against that: $6.95/mo for a business line instead of $50–$100, every feature included, and a phone number that works wherever you are. See the full rate card on our business phone service pricing page, or read what a VoIP number is if you are starting from scratch.
