Can you educate us all on the appropriate circumstances in which to use
'r'?
When you want to override the normal call progress tones.
For example, when a caller presses "0" in voicemail to be transfered to
the user's cell phone, the cell phone telco may play a message to the
caller WITHOUT ANSWERING the call. One common message is something like
"The subscriber you have dialed is either out of the area or has their
phone turned off". I don't want callers to hear that message and
hangup. So in this one specific situation I use the "r" option to dial
so the caller hears a ringing tone no matter what the carrier sends
back. Then the Dial timeout can expire and the caller can be sent back
to the user's mailbox (assuming the cell carrier didn't answer the call
and send it to the cell phones voicemail).
