asterisk users - Dec 2004 - Queue Timeout

I am using the CVS version as of July 23, 2004. Is the queuetimeout
option not available in that cvs?  If not, how do I go about applying
one of the queue patches without taking my system down?

I'm trying to redirect the call to PSTN if no one is available in the queue
or the agents in the queue do not answer. 

The following will redirect the call if no agents are logged in. But if
the agent does not answer the call will timeout and the call will be
terminated, not redirected. I've also tried to put the timeout rules in the 
queue context, no luck.

[support]
exten => 6040,1,Answer
exten => 6040,2,Wait(1)
exten => 6040,3,Playback(welcome)
exten => 6040,4,Wait(1)
exten => 6040,5,Queue(support|t|||1)
exten => 6040,6,Dial(SIP/0123456789@x.x.x.x) <- call if no one answers

[default]
exten => t,1,Dial(SIP/0123456789@x.x.x.x)


Call queue 6040:

-- Playing 'welcome' (language 'en')

Call terminated.
