Reef Voice · A Reef Telecom service
Still paying for copper?
Carriers are retiring copper phone lines and repricing what is left. Reef Voice finds the right replacement — cloud phones for your people, code-compliant lines for your alarms and elevators — and handles the switch.
$150–$400/line/mo
What a single copper POTS line commonly costs now — lines that were $30–$60 a few years ago.

How little notice a carrier can give before your lines are discontinued. Waiting for the letter is a strategy — a bad one.
The 60-second assessment
Seven questions. No email wall — you see your result first, then decide if you want us to act on it.
Your result
What are your copper lines costing you?
Drag the sliders. Most businesses are surprised by the yearly number.
Staying on copper:
Typical modern replacement:
Estimates only. Replacement range uses $20–$45 per person/line per month for cloud phone service; alarm, elevator and other specialty lines are quoted per line after a review.
What replaces what
A PBX that still works → SIP trunks
If your on-premise system has life left, we can feed it modern SIP trunks and cut the copper lines behind it. No forklift required.
Alarm, elevator, fax & gate lines → POTS replacement
Fire and burglar alarms, elevator phones, fax and door/gate lines can not become regular VoIP lines. They need code-compliant cellular POTS replacement that keeps them inspected and legal.
Already on VoIP → provider match
Contract creeping up, support gone quiet? We review your current setup and match you to a better-fit provider — or tell you honestly to stay put.

Common questions
Will VoIP work for my fire alarm?
No — and be careful with anyone who says yes. Fire and burglar alarm panels, elevator phones and similar life-safety lines need a code-compliant cellular POTS replacement, installed so the line stays supervised and passes inspection. That’s a different product from a VoIP seat, and it’s the first thing our assessment checks for.
Can I keep my phone numbers?
Yes. Your numbers port to the new provider as part of the migration, including toll-free numbers. We schedule ports so there’s no gap in service.
What does the match cost me?
Nothing. Reef is paid by the provider through our partner program when you sign up. Migration work and any phones are quoted up front before you commit to anything.
My PBX still works — do I have to replace it?
No. If the system is healthy, SIP trunks let you keep it and retire the copper lines behind it. If it’s end-of-life, we’ll show you the cloud numbers side by side and you decide.
What about 911?
Cloud phone service uses E911: each phone or app sends its registered address with a 911 call, and that address must be kept current when people move or work remotely. It works well, but it is different from a copper line’s fixed location — we set it up with you and explain the differences before go-live, not after.
How long does a switch take?
Most small and mid-size switches complete in 2–4 weeks, paced by number porting. Specialty-line replacements are scheduled around your inspection and monitoring-company requirements.

All prices and savings shown on this page are estimates, not quotes; final pricing depends on the provider, features and contract you choose. VoIP service uses E911, which works differently from traditional 911 on a copper line — ask us and we’ll explain before you commit.
