| Moderator's Note: Suspend Call Waiting is available throughout area 312
| with the possible exception of the Morton Grove CO.

Call Waiting altogether is not available on six of the eleven suburban
prefixes in the Des Plaines CO.  A customer with any of the six prefixes who
wants Custom Calling features has to accept a new telephone number on one of
the other five prefixes.

| We use *70 to turn it on, and it disconnects itself when you hang up the

In the Centel part of 312, it is 70#.  From rotary phones, I believe 70 plus
a four-second pause will do, since that is how 72#, 73#, and 74# are
implemented: rotary phones can replace the octothorpe with a four-second
pause.  Illinois Bell uses the more common *70 to disable Call Waiting, and
its rotary line substitute is 1170.

There's another difference: Centel enables flashing on all lines with Call
Waiting so that it can be disabled during a call, even if the subscriber
does not have three-way calling.

| One oddity here is that if you have two lines which hunt each other on
| busy/no answer as I do, they will never hunt if you also have call-waiting,
| since hunting requires that the line test busy, which it won't do.  But

| calls get forced over to my second physical line.  Neat!

Reverse oddity here!  In Centel's switches hunt supersedes Call Waiting.
Call Waiting will never get a chance to function on any line that has
another to hunt from it, because hunt will catch the incoming call first.
As a result, Call Waiting works only on single lines or on the last line of
a hunt group.

And there's also the toll-free calling area I have here: six hundred
fifty-seven prefixes.  Remember the good old days, Patrick?
