Obi202 - Line 1 works; not Line 2... ideas?

<< < (2/2)

Stewart:
Some telephone line cords have two wires (what's needed for one line) and some have four (the other pair is used for a second line or a special purpose).  If you look at either plug end, you can tell how many wires are there.

The OBi202 supports both lines connected through the Phone 1 port, using a four-wire cord.  This requires that the phone also support this.  If so, the jack on the phone is usually labeled "L1/L2" or similar.

The OP should try using a four-wire cord connecting OBi Phone 1 to the phone's L1 jack, with nothing plugged in to the Phone 2 port.  It's possible that both lines will work this way, with just the one cord.

If not, the OP should use two cords, with the Phone 1 port cord having only two wires, and then both lines should work fine.

JohnBowler:
There's another important point; always test with the phone plugged directly into the OBi.  US house telephone wiring is frequently wrong and most US houses aren't wired with both lines (red-green and yellow-black) connected to the sockets.

It's easy to fix this with a telephone wiring tester, and I always do that on rental properties if the tenants want to use landline, but unless a particular socket has been tested right back to the telecom point of connection there is absolutely no guarantee it does anything sane.
