Business phone service / Worldwide
Business phone service for teams anywhere, set up remotely and shipped ready to plug in.
Texwan started in Texas in 2007 and sets up business phones for companies wherever they work. We design hosted phone systems and SIP trunks, program every phone before it ships, port numbers where the rules allow and support you remotely, whether you are moving off ISDN, PRI or an old Nortel or Mitel system.
What we provide
Phones, trunks and complete hosted systems
Hosted phone systems
Cloud-hosted auto attendants, queues, voicemail to email, and desk, desktop and mobile apps, with local numbers where available. No server in your closet.
SIP trunks
SIP trunking for an existing on-premises system, with toll-fraud limits, caller ID and emergency calling set up for the country you are in.
Hardware, pre-configured
Phones and systems from Yealink, Yeastar, Grandstream and Sangoma, plus packaged and pre-formatted bundles programmed before they ship.
Migrations
Moves off PRI and ISDN circuits, copper lines, 3CX and other platforms, with numbers, extensions and call flows planned before cutover.
Legacy and odd setups
Keep a Nortel or other legacy PBX on SIP through a gateway, connect paging, door phones and alarm lines, or untangle a system nobody documented.
Emergency calling done right
Direct emergency dialing from every phone and location data where the rules call for it, such as Kari’s Law and RAY BAUM’S Act in the US, Ofcom rules in the UK or the IPND in Australia.
Outside the US
Working across borders
Shipped and set up remotely
Phones ship from the US pre-configured. Import duties, taxes and customs depend on the destination and are agreed in the quote. There is no local office or technician visit.
Local rules first
Emergency numbers, number rules, porting and equipment marking differ by country. Each city page lists what applies there, with links to the official regulator.
Where VoIP is licensed
In countries that license VoIP to local operators, such as the UAE, we pre-configure an on-premises or private system and connect it to a licensed operator.
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
Business phone service FAQ
Do you only serve these cities?
No. These pages cover places we hear from often, but setup and support are remote and phones ship pre-configured, so we work with businesses worldwide, subject to each country’s rules.
Can you give us local numbers in another country?
Often, where available from a carrier serving that country and where its rules allow. Some countries require a local address or establishment, and some license VoIP to local operators only. We check before quoting and never promise a number we have not confirmed.
Can you move us off 3CX or another platform?
Yes. We move businesses off 3CX and other platforms to hosted service, with every extension, queue and call flow mapped before cutover.
Can you keep our old Nortel or Mitel system running?
Often, yes. Many legacy systems can connect to SIP trunks or a hosted system through a gateway, so you replace hardware when you choose.
What phones do you supply?
Yealink, Yeastar, Grandstream and Sangoma phones and systems, programmed before they ship so they work when plugged in, with the right plugs, markings and radio bands for the destination.
Where are prices?
Pricing depends on users, sites, hardware, features and destination, so we quote each project. Send the basics through the form and we reply within one business day.
