Precision replacement parts
Parts for phone systems nobody makes parts for anymore.
MBAJ Designs reverse-engineers and manufactures replacement parts for legacy business telephone systems — handsets, keypads, housings, and hardware your OEM stopped supporting years ago.
01
Measured, not guessed
Every part starts from a scan or caliper measurement of your original — never a generic template.
02
Small batches welcome
Need three parts or three hundred? We tool for both, without a minimum-order penalty.
03
Built for obsolete systems
Nortel, Avaya, Rolm, AT&T, and other platforms long gone from the OEM parts list.
04
Fast turnaround
Most replacement parts ship within two weeks of sample approval.

Who this is for
Keeping new & old systems running, one part at a time
Facilities and IT teams don't rip out a working phone system just because a manufacturer stopped selling parts for it. MBAJ Designs exists for exactly that gap — compatible replacements and solutions for the hardware everyone else has discontinued.
