Hi, I've recently moved into a house that has cat5 wiring running to all of the phone jacks. I believe the jacks themselves are RJ25 jacks - that is, there are 3 pairs of wiring in the jacks (and one pair is behind the jack not tied into anything).
Anyway, I've wired up line 2 to my VOIP line and it is easy to find an adapter that splits a jacks into a 2 line jack (L1 L2 L1+2). I'd like to wire up line 3 but I'm having an impossible time finding something that will split an RJ25 into L1 L2 L3 L1+2+3.
The link below is exactly what I'm looking for but it appears to be discontinued
Thanks, arn
