[Freeswitch-users] validating dtmf digits received

[Michael Jerris]

inline is run when the dialplan in parsed, everything else is run  
later.  So read sets digits dialed after it is finished parsing the  
dialplan, if you transfer to another extensions after the read you can  
then condition on that value.
