Denver, CO Business Phone Service — VoIP from $21/mo

Denver County · Denver–Aurora–Lakewood

Built for the way Denver does business.

Denver anchors one of the largest aerospace economies in the country, with Lockheed Martin Space, Ball Aerospace, and United Launch Alliance operating across the metro and a supplier network to match. Downtown and the Denver Tech Center house energy firms, software companies, and the professional services that follow them, while the Anschutz Medical Campus in Aurora drives a major health sector. Front Range businesses tend to be distributed by default, with staff split between the city, the suburbs, and the mountains, and fvoip keeps them on one phone system wherever they log in.

Denver's 303 code is one of the originals from 1947, with 720 and the newer 983 overlaying the same territory. fvoip provides local numbers in all three, so a RiNo design studio and a DTC engineering firm each present a Front Range caller ID. Every plan includes a multi-level auto-attendant, business-hours routing, mobile and desktop apps, and voicemail-to-email with AI transcripts. Snow days do not stop calls: when I-70 closes or the office empties, the same numbers ring laptops and mobiles at home.

Most Denver businesses buy lines from Lumen, the successor to the old Qwest network headquartered here, or from Comcast Business, and both charge legacy prices. fvoip runs $21 to $49 per user per month with unlimited US and Canada calling, free porting, no setup fees, and no contracts, and typical switchers cut phone spend 40 to 60 percent. Desk phones from Yealink, Poly, and Grandstream rent from $8.99 monthly. From a 3-person outdoor-industry brand in RiNo to a 50-person aerospace supplier near Centennial, one system covers the Front Range.

Denver questions, answered

Can I get a local 303 number in Denver?

Yes. fvoip provides Denver numbers in 303, 720, and the newer 983 overlay, all covering the same Front Range footprint. Original 303 inventory is tighter given its age, but numbers are available across the overlays, and any 303 number you own ports in free.

Can I keep my number if I leave CenturyLink or Comcast?

Yes. fvoip ports numbers at no charge from Lumen (CenturyLink), Comcast Business, and any other US carrier. Local ports typically take 3 to 10 business days, and your current service stays live until cutover.

How does fvoip serve aerospace and defense suppliers along the Front Range?

Suppliers route program, purchasing, and quality calls through separate auto-attendant menus and keep engineers on the business line via mobile apps during site visits. Month-to-month seats flex with contract awards, with no penalty for scaling down.

Is fvoip HIPAA compliant for Denver and Aurora healthcare practices?

Yes. The Enterprise plan at $49 per user per month includes HIPAA compliance and a signed BAA, which fits practices around the Anschutz Medical Campus and across the metro. Smaller practices can start on Essential or Professional.

How fast is setup, and what internet do I need at altitude?

Altitude does not matter, but bandwidth does, barely: each call uses about 100 kbps, so any reliable Comcast Business or Lumen connection carries a full office. New numbers activate the same day and desk phones arrive pre-configured.
