Business phone service / Denver, Colorado
Business phone service for Denver teams that split time between the office and the mountains.
Denver companies often run a downtown or Tech Center office, staff who work from home along the Front Range and a branch or two in mountain towns where internet options are thin. That spread puts pressure on two things: 911 locations for people who move, and a backup path when a mountain office loses its connection. Texwan designs for both.
Everything is configured remotely. Phones ship ready to plug in, local 303 and 720 numbers are added where available, and existing numbers port on a date you approve.

Threat Briefing
The FCC’s RAY BAUM’S Act rules cover off-premises users too. For remote and nomadic users, a multi-line system should provide a dispatchable location automatically if it can, or let the user update it. (FCC)
The FCC National Broadband Map shows which providers report service at an address. In mountain towns it is often the fastest way to see whether a second internet connection is even possible. (FCC)

Risk and Compliance Matrix
| Risk | Control or compliance mapping | Business impact |
|---|---|---|
| Remote users’ 911 calls carry the office address | RAY BAUM’S Act off-premises dispatchable location (FCC); VoIP 911 rules (FCC) | Help is sent to downtown instead of a home in Golden |
| Mountain branch with one internet connection | NIST SP 800-34 alternate communications (NIST); FCC broadband map (FCC) | The branch disappears whenever the line goes down |
| Seasonal staff keep app access after they leave | NIST SP 800-58 VoIP security (NIST) | Former staff can still make calls on the company’s numbers |
03 / Architecture and Remediation Directives
Architecture and Remediation Directives
- Turn on location prompts in the softphone and train remote users to confirm their location when they move.
- Add a cellular backup router at any branch with a single internet provider.
- Create seasonal routing that you can switch on and off for winter and summer.
- Remove app access on the same day a seasonal employee leaves.
04 / Vendor-Neutral Verification Checklist
Vendor-Neutral Verification Checklist
Three checks you can run yourself, with or without us.
- Ask three remote users to open their app and read back their 911 location.
- Unplug the main internet at a branch for five minutes and confirm phones stay registered on backup.
- Compare your list of app users with your current staff list.
Legacy and odd setups
Old phone systems in Denver? We can work with them.
Older Avaya IP Office and ShoreTel systems are common around Denver. Many can stay in service on SIP trunks while we move users to hosted service, and we can keep door phones and paging working through the change.
How it works
Remote setup, phones shipped ready to use
- Review. Send us your current bill or a list of numbers, users and sites. We map extensions, call flows and anything unusual.
- Build. We build the hosted system or SIP trunk configuration and program each phone (Yealink, Yeastar, Grandstream or Sangoma) with its extension and buttons.
- Ship. Phones arrive pre-configured and labeled. Your staff plugs them in; no technician visit is needed for a standard setup.
- Port and support. Numbers port on a date you approve, and support is remote, with every request answered within one business day.
Questions
Denver business phone FAQ
How does 911 work for people who work from home?
Each remote user has a registered location in the app. We set it up and show them how to update it.
Our mountain office has unreliable internet. Will VoIP work?
With a cellular backup router and phones that fail over automatically, yes in most cases. We check provider options for the address first.
Can seasonal routing switch on automatically?
Yes. Routing can follow a schedule or be switched by hand from a phone.
