FAX! There is NO UDP/IP port. NO TCP/IP port. No IP Address. FAX is not IP based. Not theory at all. FUD!

And from what you have described from your setup the software itself may be vulnerable to memory bounds checks etc. You would want to research the software using lists such as this if you are truely afraid of vulnerabilities in your fax application. Again this is more theoretical then practical but you get the idea. --------------------------------------------------------------------------- This list is sponsored by: BigFix If your IT fails, you're out of business - or worse.
