Linux Software for a Cross-Platform Office

I have been working on setting up a cross-platform faxing gateway for our office. What I have have done is setup an old 500mhz computer as my testing machine and just started loading it up.

Stock Asterisk@Home install from the cd-rom open source PBX (Built on Cent-OS).
Connected Asterisk to CiscoCallManager 4.1.3
Stock Hylafax install from RPM
Setup IAXModem
Tested WinprintHylafax for Windows print-to-fax
Setup Email-to-fax with a procmail recipe
Setup gocr for OCR detection of code on the fax to link to a specific database

Here is what it looks like so far. I’ll post more info and directions when I have more time.
