Hi, 19j---94/Roland.

I see that you're with a Non-profit, so this may be a moot point... But the SX200 Analog is an ancient technology that hasn't been supported by Mitel itself for a couple decades. It's probably a late-80s/early 90s vintage. If it's at all possible, I'd suggest looking into an upgrade to at least a Mitel SX-200 EL (which would be around 2000 vintage or later).

I know, non-profits don't have the cash lying around, and work with donated older systems. Still, just some food for thought.

On the other hand, some of the posters here do still support the SX-200 analog.
