Actually, although this may sound like an elementary question, ths solution is
not as simple.  First, it can be done, because TPU does it.  When someone
PHONEs me the message is displayed at the bottom of my screen, not in the
middle of my text.  I don't know the exact mechanism used, but I can make a
good stab at it, and the rest you can get from the documentation set.  First,
open a channel to OPCOM's mailbox.  BTW, this is part I'm unsure about.  It may
be a system service other than $ASSIGN, or may be to someone else's mailbox. 
Check keywords operator message, mailbox, and broadcast in your index.  Next,
issue a $QIO to it with a completion AST.  Now that it's set up, every time you
get a broadcast message of some type (actually, I think any type) your routine
gets activated, and you can check the class of the message, text, source, etc.
If it is from PHONE, check the content of the message for the username and
compare it against your list.  If there is a match, send a message to the user
(the one running the program) that a friendly user is calling, and do whatever
you want next, including lib$spawn-ing a PHONE ANSWER command.  Be sure to
reactivate you're qio so the next message gets intercepted, too.  Excuse me for
any technical details I've gotten wrong; I've never tried this.  Good luck!
