You should check out the Wiki at 
http://www.voip-info.org/wiki-Asterisk+cmd+Dial under the section 
"Return Codes".

Basically: when dialing an extension which is currently busy, execution 
will continue in the current context at priority n+101. So you could 
have something like:

exten => 1000,1,Dial(SIP/techie,30)
exten => 1000,2,Hangup  ; goes here if techie doesn't answer in 30 secs
exten => 1000,102,Dial(SIP/trekkie,30)
