Hook-flash required to answer incoming calls prior to about 3 rings
Sarnia:
I tried to rectify this problem by deleting the OBI200 from Obitalk, factory resetting the OBI200 physically using the reset switch, and reconnecting it to Obitalk and reconfiguring it but the problem persists.
The setup is freephoneline.ca (FFL) as SP1 (primary for outbound calls, setup for 911) using the Obitalk configuration wizard and google voice as SP2, also using the configuration wizard. I only otherwise entered Obiexpert to set the outbound caller name on FFL.
The only other thing that hopefully is not noteworthy is that the OBI200 is connected to the house wiring and there are four phones connected to the house wiring.
It seems largely but not 100% consistent that on incoming calls on FFL, if it rings less than about 3 times then one hears nothing on the off-hook phone and the caller continues to hear ringing but if a hook-flash is done on the OBI200 phone then the call gets answered and a conversation can proceed. If the phone rings about 3 times or more then typically one can answer the OBI200 phone and all is fine.
While google voice is configured as SP2, I suspect/hope that it is not implicated with this problem. I have not tried to see if the same problem occurs on incoming calls on google voice.
I doubt that this represents a problem with FFL.
Does anybody have any idea what could be going on and/or how to troubleshoot?
I doubt that the following is important but the OBI200 always obtains the same IP address using DHCP on a router running Gargoyle. UDP ports 10000, 5060, and 5061 are forwarded to the OBI200.

Your obvious first step is to see what happens when you have a single phone plugged directly into the OBi.

This setup is at a relative's house which is 6 hours drive away, each way. She is living with this issue for now.
I will try with one directly connected phone (bypassing the house wiring) when I am up there in September to see what I learn. Other than that and watching the phone port status on the web page of the Obi200 and trying to enable syslog, I have no idea what I can do.
Any related guidance that anyone can provide to help me in September would be appreciated. For example what level of syslog would possibly show off-hook events?

I was able to recreate the problem periodically enough (but not always) after two rings on incoming calls even with one particular phone directly connected to the Obi200 using a short phone cable (all of the house wiring bypassed). The phone + Obi200 combination exhibiting this problem is a General Electric Big Button CID Speakerphone. https://www.amazon.com/29369GE1-Button-Desktop-Waiting-Speakerphone/dp/B00079VIFU
While I was hearing ringing on the calling cell phone, on the GE phone's receiver I heard silence plus a sort of clicking/scratching sound every few seconds (probably corresponding with the continued ringing despite being off-hook) for a few iterations during which the Obi200 web interface, showed a Status -> PHONE Port Status of Ringing (with LoopCurrent 19 or 20 mA, VBAT 14 V or 15 V, TipRIngVoltage 5 V or 6V) followed by a State of "On Hook" (while I was still off hook) with the same other parameters (LoopCurrent 19 or 20 mA, VBAT 14 V or 15 V, TipRingVoltage 5 V or 6V). Again, if we let this phone ring for three or more rings, going off-hook consistently results in the call being answered properly.
Another phone for which the problem consistently does not occur when answering shows, when off-hook, LoopCurrent either 19 or 20 mA, VBAT either 13 V or 14 V and TipRingVoltage 4V (while attached to the house wiring, in this case close to the Obi200).
While the phones are all On Hook, the Port Status is On Hook, LoopCurrent 0 mA, VBAT 55 V, TipRingVoltage 46V.
The Obi200 is hardware version 1.4, software version 3.2.2 (Build: 5898EX). There are no optional USB dongles attached. It is Ethernet wired to the router.
The port settings are all default (600 ohm, OnHookTipRingVoltage 46, OffHookCurrentMax 20, etc).
I will be back here at Christmas. What can I do to troubleshoot this problem further or might I have provided enough information now to allow someone to tell me what may be wrong and ideally what to configure to correct it?
SteveInWA:
Do I understand your post, such that the OBi-attached phone rings normally if you instead use some other phone? That would prove it's a telephone issue.
Nominal values on my OBi 200 and 202 (note that there will always be a slight variation in the numbers):
Off Hook: 20ma, 17V, 7V
On Hook: 0-2ma, 58V, 45V
Ringing: 0-2ma, 58V, 45V
Also note that the voltages shown here are DC. During ringing, a higher AC voltage is superimposed on the DC voltage, but the OBi web page won't display it.
The GE big button phone requires an AC/DC adapter (wall wart) plugged in and working. Without it, there's no telling how much current the phone is drawing when it is ringing (or attempting to ring). Your symptoms suggest that the phone is the problem.
Of course, the phone could be defective, or the ringer switch could be set to low or off.
