So I finally got to the docs on hunting under the TM Modules and there was an awesome write up and it is making a lot more sense now. 

Basic logic is to append_branch with your extensions and and manage serial and/or parallel forking by setting the q values.

The script is static. Is there a module that automatically loads registered contacts from a grouped list of extensions or is the best way to dip into the db and DIY? I would like to know how some of you have implemented hunting,

Also is there a way to set the fr_inv_timer of each branch.

Thanks in advance.
