exten => _77XXXXXXX1NXXNXXXXXX, 1, SetAccount(${EXTEN:2:7})
exten => _77XXXXXXX1NXXNXXXXXX, 2,Dial(Zap/g1/${EXTEN:9:11})

With this, the account code will at least be a separate field in your 
CDR record... I think that's what you're asking for...

You can add some logic to check for valid account codes and all that.  
Have a look at the AstCC and the Authenticate application for some ideas.
