In many areas, there is a magic number you can call to get a
computer voice telling you what number you have called from. Does anybody
know if an AT&T System 25 PBX has a similar feature to tell you what
extention you are calling from? Many times when hooking up phones around
the lab, I come accross an unused jack with dial tone in it and no way to
find out what extention it is other than to guess and try calling it to see
if it rings. I've tried picking the AT&T installers' brains; either such a
feature doesn't exist or they won't tell me what it is.
