Business phone service / Dallas, Texas
Business phone service for Dallas firms whose callers expect an answer.
In Dallas a lot of business still closes on the phone. Law firms in Uptown, wealth managers and lenders downtown, and real estate brokers across North Dallas all lose deals when an outbound call is labeled spam or a client hits a voicemail maze. Texwan builds phone systems for these offices with caller ID reputation, clean routing and records you can defend.
Phones arrive programmed with each person’s extension and line keys, and the whole system is managed from one portal, whether you have one floor or several.

01 / Threat Briefing
Threat Briefing
Since June 2021 the FCC has required voice providers to use STIR/SHAKEN caller ID authentication on their IP networks, and unsigned or poorly attested calls are more likely to be flagged or blocked. (FCC)
In a multi-floor tower, RAY BAUM’S Act Section 506 requires a dispatchable location, such as floor or suite, to go with a 911 call from a multi-line system. (FCC)

03 / Architecture and Remediation Directives
Architecture and Remediation Directives
- Port every number you dial from into the same account so outbound calls can be signed with full attestation.
- Register your main numbers with the major call analytics services and recheck labels after any change in calling volume.
- Assign a floor and suite to each desk phone and each extension that moves, and send 911 notifications to reception and building security.
- Turn recording on only for the lines and roles that need it, with a written retention period.
04 / Vendor-Neutral Verification Checklist
Vendor-Neutral Verification Checklist
Three checks you can run yourself, with or without us.
- Call five mobile phones on different carriers from your main line and note whether any show a spam label.
- Pick a phone on an upper floor and confirm the 911 location record shows that floor, not the lobby.
- Export a list of recorded lines and compare it to the people who actually need recordings.
Legacy and odd setups
Old phone systems in Dallas? We can work with them.
Many Dallas towers were wired for a PRI and a large Nortel, Avaya or Mitel system, and some of those are still on the desk. If the hardware is solid, we can connect it to SIP trunks through a gateway and retire the PRI first, then replace phones floor by floor. We also handle the odd ones: overhead paging tied into the old system, door entry lines and fax numbers that must keep working.
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
Dallas business phone FAQ
Why are our outbound calls showing as spam?
Usually a mix of attestation and reputation. We check whether your calls are signed, whether the numbers are in your own account, and whether they are registered with the analytics services carriers use.
Can each attorney or advisor keep a direct number?
Yes. Existing direct numbers can be ported, and each one can ring a desk phone, a mobile app or both.
Can you work around our building’s existing cabling?
In most cases, yes. If the building has usable Ethernet we use it. If not, we scope cabling or Wi-Fi phones in the quote.
