See chan_unistim. As of 1.0.4c, there're 2 ways to dynamically add new 
device/extension without having to edit the config. You can use an 
automatic template or let chan_unistim prompt the user for a 'TN' (I 
think it's Terminal Number). The TN method is loosely modeled after 
Nortel's auto provisioning procedure. Kudos
