johnp,
We have been around a long time and still have a lot of older systems that analog and digital phone reside on. With that in mind we are definitely seeing that new guys have no idea, and are somewhat intimidated by, what they need to know in order to solve the most basic of issues; much less MACs. This is more readily seen within the Hotel/Motel environment than in others, but older systems are everywhere.
Since our workforce is aging and getting ready to retire before all of these systems are removed will require the newer guys to get up to speed on it before we leave. I have found a few places that I think may teach the skills needed, but we are also looking into creating our own in-house program now for future reference. With that in mind I am looking into different programs and figuring out which ones to take and see what we need going forward with new technology as well.
Thanks,
TE
