Can someone tell me If the wire contacts in the Obi100 phone port are all active or not?
Normally with a modular phone jack, there are 4 wire contacts. 2 wires per line. For a 2-line phone or 2 separate lines, you could use the same jack and just use 2 of 4 wires for each line. The Obi has 4 contacts, but in most cases only the inside 2 are active and the outside 2 (for "Line2") are dummies or not active.
On the Obi100 are the second 2 wires just there for show, or do they connect to something? Is it sp1/sp2 or do only the one pair of wires actually work?
I hope this question makes sense as to what I'm asking
