The V-Portal puts the second line onto the outer pair of the "Line 1" jack (and the first line onto the outer pair of the "Line 2" jack). This is so that one could connect a 2-line phone to the V-Portal using only one 2-line phone cord. Some phones and other equipment (such as HP fax machines) tend to either connect the inner pair to the outer pair or the outer pair to ground. So using a 2-line phone cord in those cases can have undesired results.

Mediocrates join:2008-05-27 Raleigh, NC ·Sprint Mobile Broa.. ·Vonage ·AT&T CallVantage	I do know that oddly a 4-wire line worked 100% between my HP640 Fax and my AT&T Callvantage Centillium MTA-1 while that 4-wire line between my HP640 Fax and the Vonage V-Portal did not work. It has nothing to do with house wiring as house wiring does not enter into this connection. As a test I tool that 4-wire line and used to replace the 2-wire line between my V-Portal and my otherwise 100% functioning GE 2 station one line cordless phone and it does not work. When I used the 4-wire line between the V-Portal and the HP640 Fax using the 'line' port not the 'ext' port - I DO get that odd - "You have plugged your device into the wrong port warning message. So, to make a long story boring, there is a new 2-wire line in shipment to me. when It gets here I will most likely plug the HP640 Fax into the V-Portal and plug the GE phone into the ext port of the fax machine. Unless someone call verify whether a 4-pin splitter placed on the port-1 of the V-Portal and running both the fax and phone on separate 2-wire lines will actually work, or if it definitely will not.

tanline join:2009-06-25 Atlanta, GA	I had the same Problem with my HP All-In-One DeskJet Fax. When I connected the HP FAX to the Vonage Adapter with a 4 wire RJ11 - the fax would not work and actually the Vonage Adapter also failed. I found on the Internet that others with the same problem either used a DSL Filter reversed or a 2 wire RJ11. So I cut the 2 outside wires of the 4 wire RJ11 I had and it worked. No one has explained why the 4 wire RJ11 causes problems with the FAX Machine. Not sure why the DSL filter reversed would work either as I don't have any of those to look at.
