I'd say lose the priority jumping[1] and start using the return code from 
Dial to base your decision on what to do next.

So, (approximately! - in particular you might want to do a nother set of 
Goto's after the 2nd dial to play messages back to the caller, etc. if 
this is a desired feature...)

exten => _dialywildcard,1,Macro(dialout|SIP/${EXTEN}@bvoice-out,30)
exten => _dialywildcard,n,Goto(${DIALSTATUS})

exten => _dialywildcard,n(CHANUNAVAIL),Noop(We got CHANUNAVAIL)
exten => _dialywildcard,n,Macro(dialout|SIP/${EXTEN}@netlogic,30)
exten =>  _dialywildcard,n,Hangup()

exten => _dialywildcard,n(CONGESTION),Noop(We got CONGESTION)
exten => _dialywildcard,n,Macro(dialout|SIP/${EXTEN}@netlogic,30)
exten =>  _dialywildcard,n,Hangup()

exten =>  _dialywildcard,n(NOANSWER),Noop(We got NOANSWER)
exten =>  _dialywildcard,n,Answer()
exten =>  _dialywildcard,n,Playback(number-not-answering)
exten =>  _dialywildcard,n,Playback(please-try-again-later)
exten =>  _dialywildcard,n,ResetCDR()
exten =>  _dialywildcard,n,Hangup()

exten =>  _dialywildcard,n(BUSY),Noop(We got BUSY)
exten =>  _dialywildcard,n,Answer()
exten =>  _dialywildcard,n,Playback(that-number)
exten =>  _dialywildcard,n,Playback(is-curntly-busy)
exten =>  _dialywildcard,n,ResetCDR()
exten =>  _dialywildcard,n,Hangup()

exten =>  _dialywildcard,n(ANSWER),Noop() ; should never get this one...
exten =>  _dialywildcard,n(CANCEL),Noop()
exten =>  _dialywildcard,n(DONTCALL),Noop()
exten =>  _dialywildcard,n(TORTURE),Noop()
exten =>  _dialywildcard,n,Answer()
exten =>  _dialywildcard,n,Noop(Unknown dial status of ${DIALSTATUS})
exten =>  _dialywildcard,n,Playback(an-error-has-occured)
exten =>  _dialywildcard,n,Playback(please-try-again-later)
exten =>  _dialywildcard,n,ResetCDR()
exten =>  _dialywildcard,n,Hangup()

[1] Isn't priority jumping this depreciated now?
