Help needed for 110 setup
Agent88:
I presently have my 110 set up to use GV on SP1 and I can make and receive calls using my GV account using an analog phone connected to the phone port, but when I connect an RJ11 cable from the line port to a wall jack (ATT is PSTN), all phones on the wall jack loop go off-hook. The obvious result is that I cannot use my house phones because they then all indicate "extension in use". To restore my PSTN phones, I must disconnect the RJ11 cable from the Obi110 to the wall jack. Support can't figure out why, so I am giving up on this scenario and want to do this:
I wish to drop my PSTN (ATT) and want my Obi110 to connect all (GV/Voip) calls to my house phones on that disconnected line that my wall jacks are on. (I assume ATT will disconnect the service at the NID). Will the Obi110 provide dial tone/voice service or does the line port require an active PSTN connection? If I don't need PSTN service, how do I set up the Obi110 to supply voice service to my house phones?

An OBi110 will provide VoIP service(s) without anything connected to its LINE port.
If you already have VoIP service(s) working to a phone plugged in to the 110's PHONE port you have no more configuration to do. Just connect that port to your house wiring after ensuring that the wiring is completely disconnected from the PSTN.

Do not connect the OBi phone jack to your house telephone wiring/wall jacks while that circuit is energized by/connected to the outside landline. Disconnect the house telephone wiring from the outside landline first at the demarcation point (NID). Leave the earth ground protection connected to the outside landline, if possible.
For reference, here is the house telephone wiring standard:
4-conductor pair1 line1 ring, tip: Red, Green (~48vdc, 0vdc/gnd)
4-conductor pair2 line2 ring, tip: Yellow, Black
6-conductor RJ-11 plug (outside contacts 1 and 6 are not used): |1|B|R|G|Y|6|---|1|Y|G|R|B|6| (reverses end-to-end)
With 4-conductor wiring and duplex wall jacks, I like to wire the top jack for L1/L1+L2 and the bottom jack for L2. This gives good flexibility. A single 4-conductor phone cord will connect a typical 2-line phone to the top jack. Otherwise, the top jack connects line1 and the bottom jack connects line2. The OBi202 is wired similarly... PHONE1 jack is L1/L1+L2; PHONE2 jack is L2 only... a single 4-conductor phone cord from the OBi PHONE1 jack to the top wall jack gets it done.
The OBi supplies the dial tone to your phones.
The OBi PHONE jack is rated REN5... each ringing phone presents a REN load... add these up to get the total ringer loading. A modern phone is typically less than REN 1. You can always turn some ringers OFF, if not needed.

Thanks for the feedback, gents. Interesting comments... I went through this a little over a year ago in a similar situation in my vacation home. I was told that I needed an Obi100, that the Obi110 would not work. I bought a 100 which worked for about a year before it quit. I replaced it with a 200.
I also have an Obi202, which I use for my business phones, so together I have 4 Obi devices. The 110 just doesn't seem to work as advertised, at least in my setting.
I recently decided to modify my home setup. Since I kept the 110, I set it up with a GV account which has been working fine as a standalone without connection to my house wiring for some time. When I recently tried to connect my house wiring to the line port I discovered it places all extensions in an off-hook state. I was frustrated at the feeble attempt Obi support made when I made a ticket request to find out why. I had hoped someone here on the forum would venture a guess as to why this occurs.... oh well.
I gave up trying to get the line port to work and decided to drop the PSTN/POTS local voice service and thought I would do the next best thing, which I know works. YES, I know not to hook the phone port to the house wiring prior to deactivation of the phone company connection.
I wired my house phones over 20 years ago when I used a 2-line key system similar to what 202Owner described. One thing I forgot about is my alarm system is wired to a RJ31 but has been disconnected ever since I terminated the alarm hookup. It may be that I need to remove the wires from this jack even though it is not in use.

This sounds like a wiring error in your house wiring. Don't use the LINE port on the OBi (it's only to connect a POTS line to the 110) -- As has been explained previously, don't rely on AT&T - they might just shut off service at their end. For safety and for surge protection, physically disconnect the two wires on the NID (Network Interface Device or point of demarcation) coming in from the telco. Then, plug a cord from the PHONE port on the OBi to the house wiring at any working RJ-11 jack. You should get a dial tone on every phone plugged into the house wiring, if you have correctly wired the line 1 pair to the center 2 conductors.
Unplug any phone plug from the female RJ31X jack, or else it will open the circuit, thus cutting off all the downstream connections. If you are no longer using it for alarm monitoring, then just get rid of the jack and correctly connect the inbound and outbound phone wires together.
