Phone Line Issue w/Obi 110
DanielG:
We measured the settings you asked about and the off-hook voltage was 51Vdc and the current was 70mA. Is it your opinion that this is the reason the Obi 110 is having issues with POTS-related phone calls despite the fact that a standard phone is having no issues working with those same numbers?
We've had a POTS tech onsite before and they said everything was perfectly fine (even led to a NTF charge we had to pay). Is it possible that in Texas these figures are acceptable vs. your area or would you believe this to be problematic anywhere such that we need to have a tech dispatched again?
I know we're all grasping for straws but we've ruled out so much already prior to me ever submitting this thread but if these figures are absolutely unacceptable from the 110'S perspective and that device will simply never work like that, we'll need to address it either way (even if it turns out not to be the actual issue).
Thoughts?

DanielG:
I found this link by the way, and the figures we have at this one store in particular are still out of the range shown as typical, but they don't quite match with the figures you listed:

Do I understand you to say that with the OBi110 plugged into the POTS line, the audio on a separate phone plugged into that POTS line degrades?
If not, what is your most basic symptom at the simplest level?
When you said "We measured the settings you asked about and the off-hook voltage was 51Vdc" did you mean on-hook for the voltage?
DanielG:
Sorry for not being clear, it's on hook 51Vdc and off hook current 70ma. As for the issue overview you requested, here it is:
When the standard phone is plugged into the POTS line directly it works 100% of the time with absolutely ZERO issues. When the OBI is between the Phone and the POTS line there are all sorts of intermittent issues (echo, dropped words on the call, etc). We've tried many, many things (had the TELCO onsite, ran new copper from the DMarc, replaced the DSL filter on the line, replaced the OBI with multiple devices, tried different phones, tried a different Cat3 patch cable running from the POTS line to the Obi, Factory defaulted multiple 110s, tried multiple settings provided straight from Obi regarding ACimpedance/TXGain/RXGain, etc) and we're still in the same exact place. We have a phone that doesn't work when placing calls on the POTS line through the 110 and a phone that places calls perfectly fine if we remove the 110.
Ostracus:
Interesting problem. Doesn't the Obi110 run the Phone port/Line port through an A/D and D/A conversion even for POTS calls only? Remember no relay. Also the whole Ethernet half/full duplex-speed setting has been addresses?
