Questions people ask before switching

Almost always, yes. Moving a number to a new provider is called porting, and US carriers are required to allow it. We file the paperwork and track it with your old carrier. A few rural or unusual numbers can't be ported; we check yours before you commit.

Usually 1–3 weeks. Most of that is the old carrier processing the request. Complex business accounts with many numbers can take longer. Your old service keeps working the whole time.

No planned downtime. Your old line works until the transfer completes, and the new phones are tested before that moment. At cutover there can be a short window, usually minutes, where calls start arriving on Zoom.

Not until we tell you the transfer is complete. Cancelling early can release your number and lose it. A completed port normally closes that line automatically; we confirm anything else left on the bill.

If they're regular analog phones (corded or cordless home phones, many wall phones and older key systems), yes, using a Grandstream adapter from about $54. Digital phones tied to an old office PBX usually can't be reused. More on adapters.

No. The Zoom app on your cell phone and computer works as your phone. Many people use the app only; others want a desk phone for long calls or a front desk.

Yes. We call it BYOP, bring your own phone. Buy your own IP phones and we'll set them up on Zoom Phone, with the same per-device setup fee as phones we supply. We just ask that you send us the make and model first so we can confirm it works with Zoom Phone before you order. More on BYOP.

Buying is cheaper over 2–3 years. Renting through Zoom spreads the cost and includes replacement. We'll price both if you ask.

Usually not. Phones can share a cable with a computer (the phone has a pass-through port), and Wi-Fi phones need no cable at all. We plan your setup around the network jacks you already have.

Calls can forward automatically to cell phones or another number so callers still reach you. You can also keep making calls from the Zoom app over cellular data.

Phones need your modem, router and network switch powered. A battery backup (about $108) keeps them up through short outages. For long outages, use the mobile app on your cell.

Yes. Each phone is registered to a street address, and for businesses down to the floor or room, as federal rules require. Dispatch sees that location when you call. If you move a phone to a new address, the location must be updated; we show you how.

About 100 kbps each way per call. A rule of thumb is 1 Mbps up and down for every call happening at the same time. A steady connection matters more than a fast one.

Yes. Keep your fax machine on an adapter tuned for fax, or drop the machine and receive faxes as email. We test both directions before cutover.

No. They're estimates to help you plan, last reviewed October 2026. Zoom sets its own subscription prices and equipment prices move with supply. Your written quote is the final price.

Your Zoom Phone subscription is a monthly service in your name. Equipment and installation are one-time charges on our invoice. Ask us how billing will work for your account.

Yes. Phone service carries telecom taxes and regulatory fees that vary by location, often 10–20% of the service price. The estimator includes a 12% allowance you can turn off.

Not with us. Zoom offers monthly and annual billing; annual is usually cheaper per month. The care plan is month to month.
