FAX was specifically designed to work over analog phone lines. I'm presuming you have converted your phone service at home and work to be Voice over IP with Comcast cable internet. So your phone connection is going out over the internet in packets and then getting reconstructed at the other end to a voice connection. It's just going to be really flaky trying to run FAX over that. If you really really need FAX, then see if you can set it up with an analog line. There may be some more expensive gateways that will facilitate running FAX on Voice over IP, but I would just be googling to answer that. Someone else might have actual experience and cost comparisons. Alternatively, just scan to pdf and email that instead of using FAX. Of course, the other party has to go along with that solution, but that's basically where everything is going. I even submit receipts to my health care spending account that way.
