I put my desk extension (1023) into F834-1 on the 200, and it lights up the corresponding button on the 50's ext 2000 (also sitting on my desk), and vice-versa, but if I just dial the other extension, I get "You have dialed an invalid extension", so I'm left to guessing that's not actually possible?
As far as "Dial 9", yes, they are POTS lines on CO1-10, 1-9 in the 9 line group. Nobody is really using the system yet, but I'm being told, and seeing via my 700 phone that I'm always getting Line 9 on the remote, and dial my work cell, it calls my cell, if I dial my boss, I get a busy signal, but the phone isn't busy, and if I try my personal phone, I get someone else entirely. And Try as I might to set a button-to-CO, I can't seem to get it to work, so I can't retrieve a call on hold either...
