Should be an incredibly easy modification of a script I wrote to do call 
pickups. Several people have tested this script out and it seems to be 
working at other * installs. In house, we use it heavily with about 40-50 
users to pickup ringing calls.

The script would just need to be modified to not check if an extension is 
ringing - just check if the extension is 'live' - e.g. a channel exists for 
this exension. 

Once the logic of finding out if an ext is live and all the AGI stuff to get 
an extension via DTMF is done, its very simple just to issue a Manager 
'Redirect' command to redirect a call from one device to another. The key is 
to redirect the _calling_ channel instead of the _called_ channel - e.g. if a 
call came in on Zap/4-1 and called SIP/whatever, the Manager Redirect is 
issued to Redirect 'Channel: Zap/4-1' instead of SIP/whatever. 

Anyway, that is all handled by pickup.pl anyway - figuring out the channel to 
redirect, etc. If this sounds helpful or useful, let me know...

HTH & Cheers!
