Business phone service / McKinney, Texas
Business phone service for McKinney businesses in old buildings and new ones.
McKinney mixes historic downtown storefronts with new offices and medical buildings on the edge of town. Old buildings often have phone wiring from decades ago and little room for new cable, while new ones have fiber and nothing else. Texwan plans phone service around the building you actually have.
Where pulling new cable is not practical, we use wireless DECT or Wi-Fi phones, programmed and tested before they ship.

01 / Threat Briefing
Threat Briefing
Older buildings often carry analog key systems on cabling that cannot support modern network phones. NIST VoIP guidance points out that voice is only as reliable as the network under it. (NIST SP 800-58)
When a business moves, its number can come along. FCC rules let you keep your number when changing providers in the same area. (FCC)
02 / Risk and Compliance Matrix
Risk and Compliance Matrix
| Risk | Control or compliance mapping | Business impact |
|---|---|---|
| Phones on decades-old wiring with no Ethernet | NIST SP 800-58 network requirements for voice (NIST) | Dropped calls and failed installs |
| Key system with no spare parts and one person who knows it | Business continuity planning (no regulatory mapping) | Phones down for days when it fails |
| Numbers held in a former owner’s or landlord’s account | FCC number porting rights (FCC) | Losing the number customers know |
03 / Architecture and Remediation Directives
Architecture and Remediation Directives
- Survey the building first; use DECT or Wi-Fi phones where new cabling is not practical.
- Confirm who owns each phone number and get the latest bill before ordering a port.
- Replace an end-of-life key system before it fails, or connect it to SIP through a gateway.
- Put the modem, firewall and base stations on battery backup.
04 / Vendor-Neutral Verification Checklist
Vendor-Neutral Verification Checklist
Three checks you can run yourself, with or without us.
- Find your current phone bill and confirm the account is in your company’s name.
- Ask who would fix the phone system if it failed tomorrow, and how long parts would take.
- Walk the building with a phone on Wi-Fi and note any dead spots.
Legacy and odd setups
Old phone systems in McKinney? We can work with them.
Downtown McKinney still has businesses on Nortel Norstar and other older key systems. If yours still works, we can connect it to modern SIP service so you change carriers and stop paying for copper, then replace phones later. If you are on 3CX or another platform, we move extensions and greetings over in one planned 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
McKinney business phone FAQ
Our building is old. Can we still use VoIP?
Yes. If there is no usable Ethernet, wireless DECT or Wi-Fi phones avoid new cabling.
Can we keep our Nortel phones for now?
Often, yes. A gateway can connect many Nortel systems to SIP trunks, so you replace them when you are ready.
Can we keep the number our customers already know?
In most cases. We confirm the account holder and port the number to the new service.
