The other week when the Telco person was out to install my MIT Centrex
line he dialed 200 225-1111 to get back a voice identification of my
number.  (There were two lines and he wanted to know which was which.)
What's with "200"?  Is this a universal new system for calling up CO
machinery?  Or is it MIT-specific or Cambridge-specific?  The last time
I was paying attention to such things, it used to be xxx-99xx.

I'm not a subscriber to the newsgroup so please reply directly.  Thanks
in advance...
