About / Serving businesses worldwide since 2007, founded in Texas
Phone systems first. Everything on the network since.
Texwan has served businesses worldwide since 2007, and the company was founded in Texas. The work started in business telephony: ISDN BRI and PRI circuits, Nortel and Mitel key systems and PBXs, and the copper and fiber that connected them. As voice moved onto IP networks, the practice moved with it into SIP trunking, VoIP, network engineering and managed IT. Texwan is the managed IT, network and voice practice of Andrew Trainum.
Lineage
| Era | What we ran | What it means for you today |
|---|---|---|
| Digital trunks | ISDN BRI and PRI circuits, T1 voice, DID blocks and trunk programming. | PRI to SIP migrations are planned from a full inventory of DIDs, hunt groups, caller ID and 911 records, so nothing is dropped at cutover. |
| Key systems and PBXs | Nortel and Mitel key systems and PBXs: programming, moves, adds and changes, voicemail and auto attendants. | We know what legacy call flows actually do, which makes replacing an end-of-life system a translation job, not a guess. |
| Cabling | Structured copper and fiber cabling, demarc extensions, labeling and testing. | Every network and phone project starts from tested, documented cable plant. |
| VoIP and SIP | Hosted and on-premises VoIP, SIP trunks, number porting, QoS, toll-fraud controls and multi-line 911 compliance. | Voice is engineered as part of the network, with the 911 and caller authentication rules carriers now enforce. |
| Managed IT and networks | Firewalls, switching, Wi-Fi, SD-WAN, endpoints, servers and cloud tenants. | One team accountable for the phones and everything they ride on. |

Platform
Managed devices report into Ares RMM, the managed platform from Dark Edge Consulting. It provides patch and monitoring data, backup checks, alerting and the reports you receive each month.
Principles
- Evidence over assurances: every claim we make about your environment comes with a report you can check.
- Vendor-neutral advice: we recommend the right carrier or product for the job, and our checklists work against any provider.
- Plain contracts: scope, response times and pricing in writing before work starts.
