    No, the filters are only required if you have DSL service.

    Because fax machines are designed to work over standard analog telephone lines, Epson does not guarantee that fax transmission will work over VoIP phone lines (cable systems such as Cox, Charter, Time Warner, Comcast, FiOS, magicJack, and Vonage).

    Internet traffic can interfere with faxing because VoIP communicates through the internet and not through standard analog telephone lines. The data sent over the internet for a fax is digitized into packets and this process can cause data loss.
