RingCentral POTS replacement, compared with WilloWeb
RingCentral POTS Replacement is a device that connects your building’s analog lines to RingCentral’s cloud over your own internet. We replace those lines on site and run the circuit under them; your RingCentral seats can stay.
Which one fits your building
Buy RingCentral if
- Your people already work in RingEX, and you want the analog lines on the same account and managed on the same platform as their seats.
- Your sites are spread across the U.S., and you want the same device and the same vendor at every address.
- Your IT team runs the network at each site and can set the device up to RingCentral’s network rules.
Talk to us if
- You have a Bay Area building and want our technicians to replace its lines in person and support them afterward.
- You want to keep RingEX for your staff and hand us the fire panel, elevator, fax and intercom lines.
- You want those lines and the circuit under them from the same company.
If your sites are spread across the country and already run on RingEX, RingCentral is the better fit, and you should buy it.

On RingEX, with fire alarm, elevator or fax lines still on copper in a Bay Area building? Have us look at the lines.
Request a site checkKeeping RingEX while we take the building’s lines
If your staff already use RingEX, the lines still on copper belong to the building: the fire panel’s dialer, the elevator phone, a fax line, the intercom at the door. Those lines can come to us without any change to your RingCentral account.
Stays with RingCentral
Your users, their numbers and extensions, the RingCentral app, the desk phones on RingEX, and RingCentral’s support for all of it.
Comes to us
The building’s analog lines, moved onto our voice service, and the circuit we bring into the building under them. Your RingEX seats can use that circuit too, and RingCentral still runs them.
Who answers afterward
A fault on a desk phone or in the RingCentral app goes to RingCentral. A fault on an alarm, elevator, fax or intercom line, or on the circuit, comes to us. Each company answers for what it runs.
Intercom and loudspeakers, carried over
An office and warehouse on our network had its intercom and loudspeakers wired into its old phone setup. We replicated that setup to work with our VoIP service, then tested and tuned it. The office and warehouse case study
Questions from RingCentral customers
No. RingCentral sells POTS Replacement as an add-on license for new and existing customers, so when we replace the analog lines, that is a license you never add. The bill that changes is your old phone company’s: once a line is working on our service, the copper line it replaced can be cancelled.
RingCentral’s March 2025 announcement describes a “predictable monthly service rate” that “includes installation, hardware, software, service and support.” We price your building after a free estimate that carries no obligation. You pay no overage charges, and no exchange or option fees, and the rate we set does not go up at the 12-month or 18-month mark, or after. Ask both of us to put the contract term in writing next to the price.
RingCentral’s device needs a second connection to fail over to: its optional LTE, on the cellular plan you supply, or another internet line. RingCentral’s network requirements add that during that failover the device “will experience a connectivity disruption as lines register with a different IP address.” On our side, the lines run over the circuit we bring into your building. For any line that has to stay up when that circuit is down, ask what backup we would put in; we build second paths into buildings as part of our backup internet and failover service.
The authority having jurisdiction, usually your local fire or elevator inspector, approves it, whichever company does the install. RingCentral’s design and certification statements help your contractor make the case, and so does the equipment list in our quote, but the sign-off comes from the inspector. Put the specification in front of your fire alarm or elevator contractor before the cutover date, so anything the inspector will ask about is settled early. Our fire alarm panel phone lines guide covers how NFPA 72 treats a panel’s communication path.
Start with the lines still on copper
Send us the building’s address and a recent bill that still lists its analog lines. We will trace each line to the device it serves, tell you which cutovers need your fire alarm or elevator contractor present, and price the lines and the circuit together.
