Business phone service / Houston, Texas
Business phone service in Houston that keeps ringing when the weather turns.
Houston companies plan around two things phones rarely get credit for: flooding and size. A clinic group near the Medical Center, an engineering firm in the Energy Corridor and a freight broker near the Port all need calls to reach a person even when the office is closed by high water. Texwan designs hosted phone systems for Houston so the business number lives in the cloud, not in a closet that floods.
We set the system up remotely, ship phones that are already programmed for your extensions, and keep the call flows documented so a storm week is a routing change, not a scramble.

01 / Threat Briefing
Threat Briefing
Hurricane Harvey made landfall on the middle Texas coast in August 2017 as a Category 4 storm, then stalled for four days and dropped more than 60 inches of rain over southeastern Texas, causing catastrophic flooding. (NOAA NHC)
A phone system that depends on one building’s power and one internet circuit goes down with that building. NIST contingency guidance treats alternate communications as part of any recovery plan, not an extra. (NIST SP 800-34)
02 / Risk and Compliance Matrix
Risk and Compliance Matrix
| Risk | Control or compliance mapping | Business impact |
|---|---|---|
| Main number terminates on an on-site PBX in a flood-prone suite | NIST SP 800-34 alternate site and communications planning (NIST) | Every caller hears a dead line or busy signal for the length of the outage |
| Remote staff dialing 911 from a softphone with the office address on file | FCC interconnected VoIP 911 registered location rules (FCC) | Dispatch goes to the wrong side of a very large metro |
| Recorded calls and voicemail that contain patient details | HIPAA Security Rule (HHS); Texas Health and Safety Code Ch. 181 (Texas statute) | Privacy exposure from mailboxes and recordings nobody reviews |
03 / Architecture and Remediation Directives
Architecture and Remediation Directives
- Host the main numbers and auto attendant in a data center outside the flood zone, with a pre-built storm mode that rings mobile apps first.
- Keep a written list of every DID, hunt group and after-hours rule so routing can change in minutes from a phone.
- Require each remote user to set a dispatchable location in the app, and review those locations each hurricane season.
- Set recording retention and voicemail-to-email rules that match your privacy obligations, and turn off what you do not need.
04 / Vendor-Neutral Verification Checklist
Vendor-Neutral Verification Checklist
Three checks you can run yourself, with or without us.
- Flip the system into storm mode during business hours and call the main number from an outside mobile; it should reach a person within three rings.
- Ask two remote users to open their app settings and read back their registered 911 location.
- List who can listen to call recordings today; if the answer is everyone, narrow it.
Legacy and odd setups
Old phone systems in Houston? We can work with them.
Plenty of Houston offices still run an older Nortel or Avaya system that works fine on the desk but sits on copper or a PRI the carrier wants to retire. We can keep that hardware in service behind a SIP gateway while you move users over in stages, or cut over to a hosted system in one weekend. Moving off 3CX? We map your extensions and queues first so nothing gets dropped.
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
Houston business phone FAQ
Can calls keep working if our Houston office loses power?
Yes, if the system is hosted. Your numbers live in the cloud, so when the building is dark we route calls to mobile apps, another office or a forwarding number. Desk phones come back on their own when power returns.
Can the phone menu offer options in other languages?
Yes. Auto attendants can offer Spanish, Vietnamese, Mandarin or any language you record, each with its own queue or ring group.
Do you need to come on site to install?
Usually not. We program the phones before they ship, so your staff plugs them in. If you need new cabling or a site survey, we scope that in the quote.
