Summary: [patch] Sending out unnecessary PROCEEDING messages
breaks overlap dialing
Description:
chan_dahdi sends out a PROCEEDING message as soon as a call has a match in
the dialplan.
I think sending this message is unnecessary and can be harmful.
I think it should only be sent when Dial() is called with a definitive
destination.
So far I thought chan_dahdi was unable to do outgoing overlap dialing, but
I just found out that it does, but sabotages itself.
If you have an
exten => _N!,1,Dial(dahdi/g1/${EXTEN})
and use overlap dialing, the trouble is that you get a PROCEEDING after
you dialed the first digit which will tell the phone that dialing has
finished.

----------------------------------------------------------------------
The issue18509_early_media_v1.8.patch file incorporates the
issue18509_cause_codes_trunk.patch file and allows outgoing overlap dialing
to hear dialtone and other early media.
1) Combines several flags into a single enum value representing call
progress level.
2) Allows multiple PROGRESS messages to be sent.
3) Adds better protection from sending out of sequence messages.
4) Added diagnostic messages for deferred overlap digits handling corner
cases.
