With analog Zap you cannot do this.  With ISDN you can do this (if you 
provider allows you to).  See the "noanswer" option to Playback. 
Background should not support this since you can only SEND audio before 
answer, not receive audio/DTMF and Background is only used when you need 
to reveive DTMF.
