Asterisk assumes an analog interface (x100p, TDM4XXX) to have answered a 
dial command as soon as the dial command completed successfully.  You may 
have some success with using callprogress=yes, however, this may very well 
cause other issues as can be seen if you do a google on callprogress.  So 
in other words, your dialplan isn't working as you suspect because as soon 
as asterisk picks up the line on one of your x100p cards and issues the 
dtmf to the telco, it assumes the line has been answered (and technically 
it has, the telephone company's switch has answered your call request, and 
will now just pass audio back to you, whether it's a ring, busy tone, or 
someone's voice, and without call progress you won't know the difference 
(at least asterisk won't).  The 10 second timeout never makes it into the 
decision, the line has been answered before 1 second passes.
