Thank you for your time. This post is simply to bring up what I believe may be a small typo. Love 3CX and want to make sure to help if I see something looking 'odd' in the software or support documentation. http: //www.3cx.com/sip-phones/linksys-spa-3102-fax/ No longer available. New link: http://www.3cx.com/sip-phones/ Step 7 Says "Connect the Fax Machine to the LINE PORT in the Linksys SPA 3102" The 3102 has (2) RJ11 ports, (1) FXO and (1) FXS. The FXO should be marked 'LINE', while the FSX should be marked 'PHONE'. The FXO receives dial tone while the FXS supplies dail tone. So according to the instructions, you connect the fax machine's physical phone cable to the LINE(FXO) port. Which the fax machine's phone cable should be connected to the PHONE(FSX) port on the 3102 as to provide the fax machine with a dial tone. Maybe I am incorrect, please let me know.
