3Com/HP NBX

The workhorse IP-PBX system that started the office VOIP revolution back in 1998. Through generations of hardware and software revisions in over a decade of active production, this system and its larger VCX enterprise variant have powered everything from startups to school districts.

Resource Telecom is the last active San Francisco Bay Area support provider for all generations of legacy NBX systems. We continue to maintain an extensive hardware spares inventory as well as a library of all software releases from R4.0 to R6.5.

If you are determined to keep your NBX system up and running, we strongly recommend the Resource ASA to ensure regular system backups and access to our extensive local parts inventory and 3Com Certified NBX expertise.
