Local Detroit numbers — or keep the one you have

Any device

Desk phone, laptop, or mobile app — one number everywhere

Scale seats up or down as your team changes

A Detroit number that isn't tied to a building

Customers trust a local number. With a 313 or 248 line you look like the Detroit business you are — but the phone system lives in the cloud, so it works the same whether your team is at the office, on a job site across Wayne County, or working from home.

And you're not buying a phone system anymore. Seats are month-to-month and scale as you hire, so a growing Detroit business can start with a handful of lines and add more in minutes — no forklift upgrade, no closet full of PBX hardware to maintain.

  • Local 313, 248, 734 numbers, or port the number you already have
  • Calls, business texting, video meetings, and voicemail in one app
  • AI transcription, call summaries, and an auto-attendant / IVR
  • Works from any device, anywhere — office, field, or remote

Business Phone (UCaaS) in Detroit — frequently asked questions

Can you replace our phone system with a cloud (UCaaS) solution with a local Detroit number?

Yes. Our UCaaS platform is a full cloud phone system — calls, business texting, video meetings, a contact center, and business cellular — with AI transcription and IVR. We provision local 313, 248, and 734 numbers, port your existing lines, and you can keep desk phones, go fully mobile, or both.

Can I get a local Detroit phone number?

Yes — 313, 248, 734 area codes are all available, and we handle the setup. You can point several local numbers wherever you like.

Can I keep my existing number?

Yes. We port your current numbers over — including your main line — with no downtime, so customers never notice the switch.

Do you have plans for small or growing businesses?

Yes. Pricing is per seat and month-to-month, so you start small and add lines as you hire. Ask us about current promotions for new Detroit businesses.

Does it work for remote and field teams?

That's the whole point of cloud phone. The same number rings on a desk phone, a laptop, or the mobile app — so it doesn't matter where your people are across Wayne County.

Do I have to buy desk phones?

No. Many Detroit teams run entirely on the app on laptops and phones. Keep or add desk phones if you prefer — it's your call.
