[Asterisk-Users] Help on directed Call Pickup

[Cristian Manoni]

Is Directed Call Pickup supported in asterisk? 
(http://voip-info.org/tiki-index.php?page=PBX%20Call%20Pickup)

The group call pickup works well, but I can't make directed call pickup:

example:
Someone is calling 202 (my phone, GS BT101), i stay near ext. 230 (Cisco 
7905g), i want capture this call:
i compose the pickup ext (*8)  followed by my ext (202); after composed 
*8202 i hear busy tone and 202 continue ringing

I searched in wiki and mailing lists but there is no more documentation

Can someone help me?

Thanks
