2 Voice Lines in a Cat5 Env

Does the following work? I have two phones in room A. I run a cord from
Phone 1 and Phone 2 into a 2 line/1 line splitter. I then plug the
splitter into a RJ45 patch panel. Cat5 8 wire cables run from that
patch panel to a patch panel in Room B. I plug another 2 line/1 line
RJ45 splitter into the patch panel, then run normal phone cables from
the splitter to two phone outlets. Yes, I know there are better ways to
do this, but this seems cheap and I have the parts (making it very
cheap.)

[TELECOM Digest Editor's Note: No reason it should not work. I use 2
line into 1 line splitters here on my PBXtra. Trouble with the PBXtra
is it does _not_ pass caller ID, so I have to pick off the caller ID
detail _prior to_ the incoming calls (from landline or Vonage) getting
fed into the PBXtra. What I wound up doing is feeding the two 'trunk
lines' (Vonage and landline) through two 'line splitters', one way
going to the PBXtra, the other side of the two splitters feeding
into an AT&T two lines in/one line out device. The AT&T device listens
and grabs whichever line is ringing and funnels it out supposedly to a
single line phone but in my case, a caller ID box, which then
responds to whichever line sent in ringing current. The other side of
each of the two line splitters takes Vonage and landline into the PBXtra
device. Furthermore, on the side of the splitter(s) which feed the
'two into one out' device from AT&T, I also have a common ringer in
order to be able to pick up on and hear the ringing cadence, or
'ring-ring' signal from my distinctive ringing line, which otherwise
would be useless since although PBXtra _can_ react to 'ring-ring' or
'regular ring' all it can put out on its own common audible is a
single ringing signal. So, if you call on my 800 number (which feeds
into and triggers the distinctive ring-ring line), what I will actually
hear is 'ring-ring ... ring' (the delayed single ring is the PBXtra
signaling me. Better than nothing, I guess. If you combine the
splitters and such correctly without getting confused at first, as I
did, then you can get quite creative in how it all works. The only
time mine *might possibly* screw up would be if a call came in on
Vonage at the very same instant a call came in on landline. The AT&T
device would choose one, and ignore the other, at least until the
one it chose got answered, then I presume it would toggle over and
take the other line. So rare in my case, I am not concerned about
it. PAT]
