Per Extension fax e-mail address

Hi guys. I’ve been using Trixbox 2.6 and I like the ability to set fax destination per extension.

I have a test machine I have a self complied version of * 1.6 with the newest 2.5 freepbx, but on this system I don’t see fax handling under each extension, I only see it in the trunk section. Is way to get that functionality set-up?
