I have had absolutely no trouble sending faxes using a HOT "voice" line. I used an old Dynamode external fax modem, a USR 56k external fax modem, and when I switched computers to one with only one serial port and a UPS in it, an Intel chipset HAM. All were done from a Linux system running Hylafax. About a year ago I asked around and got the following answers in relation to sending faxes outside of Israel using VoIP "lines". None of the people responding that had cable modems were able to do it. HOT technical support told me that it did not work due to the design of their network. Several of the people responding had aDSL lines and were successfull. One sent his faxes to Canada, one to the U.K. and several to U.S. No one ever answered back with exactly who their service provider was. Questions posed to the Hylafax list were answered that it was not likley to work, and no one had ever reported success. I have a Vonage line provided through AmeriFone. AmeriFone customer support said they had questions from customers, but no reports of success. That could mean that there are people doing it and have never said anything, while the customers who asked, never got it to work. Vonage changes the provisioning of the line for fax calls. It's permanent if you have a business contract, they give you a second "line" for faxes. If you only have voice service, you can switch to fax mode for the call by preceding the number with "*99". Experiments using hylafax, several external modems, with and without "*99" and I think every possible combination of speed and other parameters failed, so I gave up. I have a 5m/256k cable modem, use a Linux system as a router and tried with nothing else using the line and wondershaper on and off. I also found that my HP combination printer/scanner/fax using two cheap long distance carriers, 017 and 018, failed to the same fax machines I was trying to call. If you have access ANYWHERE to a computer with a modem on a phone line, IMHO the best option is to install a Hylafax server on it. Hylafax has a good network interface and if you really worry about security, you can set up a shell script to scp the file to a temporary location and then use ssh to issue a sendfax command.
