Summary:                    [patch] Sending DTMF when receiving the PROGRESS
status
Description: 
Some telco account code services (like Allstream here in Canada) required
that the account code DTMF be send as soon as the PROGRESS status is
received but before the channel is considered "Answered" by Asterisk.

When dialing manually this is not an issue as the user hears the beeeep
and punch in the correct DTMF account code.

However when using call files or AMI to initiate the call, the D() flag in
app_dial does not work as D() only sends the DTMF when the channel is
answered.

---------------------------------------------------------------------- 
I would like to mention that this feature has been asked for by several
different students in the Asterisk Bootcamp, so I hope that "Progress" can
be made on it.  It needs to work both on Zap channels (PRI or CAS) and VoIP
channels (SIP and IAX), so that it can be used to send account codes or
other charge information to providers before they answer.

The "w" needs to be supported to allow delays required by the remote
equipment.
