I set up a hylafax server on Ubuntu Edgy, with the Avantfax front end. It worked very well for about 6 months, then failed. I couldn't find the failure point.
Since it was a test setup, I dumped it. Loaded Ubuntu Jaunty and tried again. This time the Avantfax front end was no good. Same in CentOS5. Trying in PCLinuxOS, but having issues loading on older PC (crappy optical drive).
My goal is eventually to have multi-line fax to email (and email to fax). I'm currently using a Class 1 modem (Multitech Multimodem 56k) attached to the serial port on a PC. I've heard that Class 2 modems are far more effective, but much more expensive.
What faxserver's / modems have you tried? What was the most stable / successful? What was the worst? I'm tired of trial and error.
