It's a short ethernet cable to my switch, and a short phone cable to my homes phone wiring - a 110 block.
It doesn't seem like it could be wiring, once it's up my wife can talk for hours on end with her sister with nary an issue and no voice quality issues. It's only once it's been idle for a while that there's an issue. I'll need to be a bit more methodical about how long, and checking the ObiHai status first.
It is entirely possible you have an intermittent high resistance fault on your house wiring which causes off-hook current to fall below the threshold that an OBi recognises as being off-hook.
Temporarily wire a base station or an ordinary phone directly to the OBi and see if the fault still occurs.
I agree with Geoff, but to put it more accurately, it would be a
low impedance condition, likely caused by two of the house wires shorting together somewhere, possibly in a wall. This is pretty common, caused by things like a contractor who shot a nail or staple through the house wiring, or a rodent that chewed on the insulation, and it could take years to show up.
You may be able to see this for yourself: don't pick up the phone. Instead, log onto the OBi (either via the portal or its local web page), and go to Expert mode, Status --> PHONE status. Look at the voltage and current.
If the wiring is good, it should say "On Hook, the current should be 0ma or at worst, 1 or 2ma, and the TipRing voltage should be around 45V. If the wiring is defective, the status will show "Off Hook", the current will be higher (perhaps as much as 20ma), and the voltage much lower, around 6V.
Of course, you can also look at the phone LED on the OBi. When it's on-hook, it is lit steadily, and when it's off-hook, it blinks slowly.
Note: these values were taken from an OBi 200 and a 202, so your 100 model may have slightly different numbers.
Like he said, disconnect your OBi from the house wiring completely, and instead, plug the cordless base station into the OBi with a known-good RJ-11 phone jumper cord.
