Summary:                    [patch] Allow app_dial to provide 'tone while
ringing' like 'option m' which will provide 'music on hold while dialling'
Description: 
Application is to allow asterisk to be an ISDN providered to attempt
delivery of calls over Cellular Trunks connected to asterisk, if it cannot
deliver the call then signal CONGESTION to the calling party switch, who
will then respond appropriately by delivering the call out over its PSTN
connection.

Currently this can be achived, with option 'm([classs])' in the dial
command, which will indicate PROGRESS to the calling party and provide moh.
But it's just not right to play music as a ring tone.

option 'r' from app_dial indicates 'RINGING' to the calling party, which
is fine if you don't then what to indicate CONGESTION.  Because the calling
party's switch already believes asterisk can deliver the call, it won't try
an alternative.

The patch I have provided doesn't change the default functionality of
option 'r' but adds to it.
Like option 'm', which will play a 'class' of music as defined in
musiconhold.conf, option 'r' will play a 'tone' as defined in
indications.conf, it will also indicate PROGRESS to the calling party if a
tone is defined, otherwise it will still indicate RINGING.

One of the differences that you indicated on the mailing list between m()
and r() was that m() provided Progress, while r() provided ringing, and
that you could change from Progress to Congestion, but not Ringing to
Congestion.  Would it make sense to you to allow the r() option to take a
second parameter, which allowed it to also provide Progress instead of
Ringing?
