Elevator phones: same phone, new line
The elevator phone stays in the cab, on the same wiring, calling the same number.
How it works
The box replaces the copper where it comes in. No work in the hoistway or machine room. We test a call from the cab; your elevator contractor checks it on their normal inspection.
- No new device, no reprogramming
- Two boxes on a post at the road, solar powered
- Copper business lines are billing $200–2,700 a month. Cellular service for a line typically runs $15–45 a month.
Ooma found about 50% of the elevator lines it checked were already dead before migration. A test call during the survey shows which ones.
