I don't know Asterisk.  I suspect that you could do this with a
non-ISDN trunk.  I suspect Asterisk can deal with "dial pulse"
signalling.

The two time out idea is interesting.  I suspect that traditional PBXs
wouldn't be able to deal with that.  Again, I Asterisk probably could.

We're using Asterisk at MIT to collect the digits - because we
couldn't get our PBX to do the right thing.  So you dial an access
code "*0"; which will connect to Asterisk; Asterisk will ask for the
user number and a "*"; then ask for a domain number and a "#".  Or at
least that's the current idea.  But we aren't worrying about
supporting rotary dial phones.  And we're not worrying about
supporting touch-tone phones that don't have "*" and "#".  And we
decided that we did want to send calling number - so we are using a
PRI - which I think precludes doing a "cut-through" trunk to pass dial
pulses.  But otherwise the "two timeout" idea may be a better idea
than my "trailing ITAD length" suggestion.
