asterisk users - Sep 2005 - Routing depending on sip response code?

Hey all, 
I'm trying to create redial on busy for my users, but haven't the
foggiest
on how to make asterisk route depending on the status code returned over SIP
(483, Busy Here?). . . anyone know how to do this?
 
Thanks

Not sure if you can catch the busy from SIP, but sure you can catch the 
BUSY status of asterisk. Please read the docs about $DIALSTATUS variable in 
voip-info.org <http://voip-info.org> i think that will suite your needs.

I have something like this:

[macro-catch_dial_response]
exten => s,1,GotoIf($[${ARG1} = NOANSWER] ? 11 : 2)
exten => s,2,GotoIf($[${ARG1} = CHANUNAVAIL] ? 22 : 3)
exten => s,3,GotoIf($[${ARG1} = BUSY] ? 33 : 4)
exten => s,4,Macro(generic-handler)
exten => s,11,Macro(noanswer_handler)
exten => s,22,Macro(unavail_handler)
exten => s,33,Macro(busy_handler)

where the argument is the $DIALSTATUS variable, i could have use it 
directly, but i think is better this way. So i have different macros to each 
thing i need to do.

Best Regards.
