Business phone service / Austin, Texas
Business phone service for Austin teams that are rarely in one place.
A lot of Austin companies have a small office and a large staff that works from home, a coworking space or the road. Tech startups, agencies, nonprofits and firms that work with state agencies need a business number that rings on a laptop, a mobile app and a desk phone at once. Texwan sets up hosted phone systems built around that hybrid pattern.
New hires get a working extension the day they start. For anyone who wants a desk phone, we ship it pre-configured to their home or office.

01 / Threat Briefing
Threat Briefing
During the February 2021 winter storm, ERCOT ordered rotating outages across the Texas grid, and many offices and homes lost power for days. (ERCOT)
For hybrid teams the bigger risk is identity. A phone admin portal without MFA lets anyone with a reused password forward your main number. NIST VoIP guidance treats management access as a core control. (NIST SP 800-58)
02 / Risk and Compliance Matrix
Risk and Compliance Matrix
| Risk | Control or compliance mapping | Business impact |
|---|---|---|
| Phone admin and user portals protected by password only | NIST SP 800-58 management access (NIST) | Call forwarding changed to an attacker’s number |
| Home workers whose 911 location is the old office | FCC VoIP 911 registered location (FCC) | Emergency services sent to an empty building |
| Calls that depend on the office’s power and internet | NIST SP 800-34 alternate communications (NIST) | Customers cannot reach you during a regional outage |
03 / Architecture and Remediation Directives
Architecture and Remediation Directives
- Turn on MFA for every admin and user portal and remove shared logins.
- Have each remote user confirm or update their 911 location in the app when they change where they work.
- Make the mobile app the backup ring path for the main number so an office outage only changes where calls land.
- Remove extensions within one business day when someone leaves.
04 / Vendor-Neutral Verification Checklist
Vendor-Neutral Verification Checklist
Three checks you can run yourself, with or without us.
- List every person with admin rights on the phone system and confirm each one uses MFA.
- Ask three remote employees to read their registered 911 address from the app.
- Unplug the office internet for five minutes during a quiet hour and call the main number.
Legacy and odd setups
Old phone systems in Austin? We can work with them.
Some Austin offices inherit a phone system from the previous tenant, often an older on-premises PBX nobody has the password for. We can recover or replace it, port the numbers, and move everyone to hosted service without a gap. Teams leaving 3CX get extensions, queues and voicemail greetings rebuilt on the new system before cutover.
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
Austin business phone FAQ
Can people use their business line from a personal mobile?
Yes. The mobile and desktop apps place calls from the company number, so personal numbers stay private.
How long does porting our numbers take?
Porting timelines depend on the losing carrier and whether the port is simple or complex. We submit the request, track it and keep your current service live until the port completes.
We only have five people. Is this worth it?
Hosted systems scale down well. Small teams get the same auto attendant, voicemail and app features as larger ones.
