Greetings,
I thought I would pass this little tip along. I routinely install and configure Asterisk installs for customers in the southwest United States. This past week I had to buy a new Fax machine for my home office and decided to eliminate my analog line from my provider.
I pulled a Linksys PAP2T device from stock, changed the RTP packet size to 0.020 (which is standard operating procedure for fax devices), connected it to my PBX here at home. I then drove down to Staples and picked up a cheap Brother MFC-295CN.
I brought the Brother back to my home office, connected it up and went to configure it when I came across this configuration option:
Press Menu, 0, 6.
Press a or b to choose Normal (or
Basic(for VoIP)).
Basic(for VoIP) reduces the
modem speed to 9,600 bps. Unless
interference is a recurring problem
on your telephone line, you may
prefer to use it only when needed.
Normal sets the modem speed at
14,400 bps. (Default)
Press OK.
Press Stop/Exit.
Now… I know most fax machines allow you to adjust the connection speed but this is the first time I have ever seen “VoIP” specifically spelled out on a fax machine configuration screen.
I’m going out on a limb here and wondering if Brother/HP and others may have a marketing opportunity by building in Asterisk/SIP support directly into the device. It would be nice to connect just an ethernet cable, configure it as an extension on a proxy and emulate an analog line over RTP. I’m guessing it would not be terribly difficult to build that PAP device into the scanner/fax directly.
