I have never used any Inbound Fax software, so I got quite a shock when I visited www.electrasoft.com (the site of the fax machine documentation)to find that their FaxMail was not Freeware but is shareware and costs $59 USD - you can probably buy a low end scanner for that price. I didn't see the reference to Netzip.exe in the documentation.The only Fax Freeware that I could locate in a hurry is called 'FreeCall Centre' at the 'Only Freeware' site. There is a Pro version which costs real money, but the Freeware version looks like it could do the trick.
I'm only operating on intuition here. Any fax software users around?
