Using SendDTMF() works to call the second number, but when I take the
call, there's no actual call since Dial() isn't used:

============== extensions.conf
...
exten => start,n,Flash()
exten => start,n,SendDTMF(456789)
exten => start,n,Wait(10)

exten => start,n,Hangup()
==============

Maybe I'm the first Asterisk user to want to set up a conference call
through a single POTS line which supports that PBX feature :-/
