Summary:                    DTMF autogeneration (repeat last DTMF after change
of line)

same pb as http://bugs.digium.com/bug_view_advanced_page.php?bug_id=10084

it reads extension, then ask for password and repeat the last DTMF of
extension in password:

the first DTMF arrives normally and pass through
channel.c:2346
channel.c:2392
channel.c:2402

then it seems to activate queue flag or emulation or defer, for the next
DTMF:
channel.c:2346
channel.c:2382
channel.c:2465

At this time, a dtmf seems to be kept in a queue.

when jumping to another line in dialplan (like from vm-mailbox to
vm-password), it releases the DTMF queue by repeating the last DTMF:
channel.c:2346
channel.c:2392
channel.c:2402
if it's within the same line (read a full DTMF string) it queues but
doesn't repeat.

All my DTMF are seen as 0ms long, I don't understand why, it's pstn to iax
chan with an asterisk 1.2 on the gw side.

I greped source for defer dtmf, queue dtmf, dtmf emulate, duration dtmf,
etc ...

iax.c is only chan that has defer flag settings.

But I'm not coder, unfortunately.
