I started working on PBXs in the early 90s and loved it. I had a computer as a kid and was a fairly decent programmer and I continued to develop those skills. Through the 90s I was a PBX administrator for 17 sites, then a field technician, then a customer managing voice/voicemail/WAN, Then responsible for dial-up at a major ISP. Right before Y2K I made the jump to “Professional Services” consultant in telecommunications. In the early 2000s, this was typically IVR design with host integration and screen pops for call centers. Back then, shaving 30 seconds per call in a busy call center could add up to serious money. I’ve been a vendor, a customer, an employee, and a consultant and I’ve watched the telecom industry change. Old-school phone guys had to adapt or die. I consider myself very fortunate to have adapted. And I have never stopped learning.
