I never thought this late in my career I'd be working with an AT&T 5ESS! Of course it's being decommissioned, but it has at least a few years to go, which at that point I may be retired. The site as ISDN/Avaya 8510 phones that I've worked with before with a previous company's Definity PBXs. Also didn't think I'd use Procomm again! It all comes back to me.

I wonder - does anyone here still work with the 5ESS?

Southwestern Bell bought out AT&T and took the AT&T name in 2005. They acquired Bell South in 2007.
