asterisk users - Jan 2008 - Custom Pickup and Transfer dial string

Hi to all,
i already searched the archive without finding a solution to my problem.
I have asterisk installation 1.2.18 to support multiple virtiual PBXs.
I use SIP peer in the format <ID>-<EXT> to let every virtual PBX to
share the same numbers of EXT.
Ex.

(PBX ID 10 Extensions)
10-101
10-102
10-103

(PBX ID 20 Extensions)
20-101
20-102
20-103

I use some rules in the dialplan to let users of this pbxs to dial  
only EXT to call other extensions of their PBX.
So i add the pbx ID statically to the called number if it is an  
extension.
Now i have to realize the pickup call and blind and attended call  
transfer.
As i read in the documentation the standard codes *2 for transfer give  
me the dial tone to dial the extension to
transfer at but i need to transfer the call not to the EXT but ID-EXT .
Have you any idea on how to realize this for Pickup and call transfer?
The end users don't have any idea of the ID part of their extension so  
i have to let them dial something like *2101 and
transfer the call to 10-101 . For the pickup i need them to dial  
something like *8101 and answer the call ringing for 10-101.
I already thought a solution for the Pickup to use the application  
Pickup joined to a custom pickup code and a custom string in
the command it self, but i dont have a solution for the call transfer.
Thanks in advance for help.
Bye,
Marcello

If your working with Virtual PBX then why not set your users with there own 
rules and normal extension numbers in there own context.  You can have many 
context.

That way only extensions you allow to see the context there in will have 
those options.
