Hooking up a fax machine in an office with uverse

[doohinkey]

I have a new wireless printer /fax in an office with uverse.  The uverse is plugged into the wall jack  in my office.  I share to uverse with another officemate.  The officemate has a wireless fax that is hooked up and working.  She has 2 phone lines.  Her phone with 2 lines is hooked up to wall jack 1 and her fax is hooked to wall jack 2 and works.  I also have 2 other phone lines in my office.  The uverse is hooked up to wall jack 2 and the phone is hooked up to line 1.  I have a splicer and have tried hooking up the fax to both wall jacks.  It doesn't work either way.  I tried unhooking the uverse from wall  jack 2 and hooking the fax back into wall jack 2, which is exactly how my office mate does it, but it doesn't work.  I also tried hooking the phone directly to the fax machine.  Then the phone doesn't work.  The printer works and the uverse does also.  Anybody have a suggestion that would work.?

I DSL filter was suggested.  The problem is the the fax can't detect a phone line.

Do you have a 3800 RG or something else?

Sounds like you have u-voice - the tel is connected to the RG. But, your officemate has POTS not connected to u-verse. Does your fax work on those jacks?

Your connection from wall to RG is the u-verse signal. You cannot connect the fax to that. The U-verse dial tone comes out of the RG & goes directly to the phone because you only have one U-vers phones. The other two are POTS? but you do not want to use them for the fax? Did you try the fax on them?

If you want to use the u-voice line you should connect the fax to the RG where you have dial tone. You should be able to use the splitter to include the phone or does the fax have two jacks ( one for the phone).

Are you using the cord that came with the fax or a different one?
