Just for a laff or two, what is the oldest phone system you have worked on recently? A small amount of our cutomers still have the 6X16 KSU and a mini Startalk Flash v/m. Have seen some old 8X24's with DR3 s/w and others still using the old Startalk A,B,or C v/m's.. (could never figure the diff between those three...lol).
