Summary:                    pulse and hardware dtmf digits not detected in
chan_dahdi/trunk
Description: 
sig_analog (in the chan_dahdi rewrite) fails to detect pulse digits events
as well as DTMF up events sent from DAHDI.

The events 'pulse digit N', 'dtmf digit N down', and 'dtmf digit N up' are
marked by (N | 1<<16) , (N | 1<<17) and (N | 1<<18), respectively. See
dahdi/include/user.h .

However in chan_dahdi.c:my_get_event() , the raw event number is filtered
through dahdievent_to_analogevent() . Which does not find those events and
thus returns ANALOG_EVENT_ERROR . This has the unlucky value of 13. Sadly,
though, computers are over-rational and don't consider 13 as an error
value. And generally this functionality is missing.

Generally implementing pulse dialing should be simple. Supporting DTMF
down/up events involves muting the line.
