Try replacing the first step above with:
  exten => _9.,1,Dial(Zap/4/w${EXTEN:1})

Note the "w" in the above means wait for about a 1/4 second before 
sending the number to the central office.

Some central offices are not ready to receive digits as quickly as 
asterisk sends them out. In fact, some users have to use multiple w's 
(as in Zap/4/www${EXTEN:1} to wait for the equipment to settle down.

Give that a try and let us know if it corrected the problem.
