Can anyone utilize fax machines on packet 8..if so how? I have tried many things and even used different fax machines without success. I have previously been able to at one time but not so within the past year possibly. It drives me crazy not being able to fax when I need to do so.

Also are there any VoIP providers that you can fax with if not packet 8?

Try searching through the Packet 8 forums http://community.packet8.net
Some report success with different fax machines set a certain way - like overseas mode (whatever that is) and lowering the baud rate. There's also some discussion at dslreports.com.
