1 week with obi200. Just works whenever it wants to?

I am getting similar occurrences, but my network config needs some work.
I may have too many routers.
Has your router been setup to port forward the proper ports used by the OBI?
It is rarely necessary to forward any ports to make an OBi work.
And even when it is necessary the symptoms are not sporadic in the manner the OP is experiencing.

Correct. Also, I MAY have fixed the issue with inbound and outbound calls. I got the OBI200 to replace my Comcast home phone. I originally placed the unit near my modem and then connected the RJ11 to it there. This is in a closet in the master bedroom and the phone is in the study downstairs. This was using the home phone wiring which has ONLY been used for voip (no outside connection). I'm not sure if the OBI200 has an issue with wire length but I moved it to the study (thankfully we have a switch there already) and connected it directly to the phone. Inbound and outbound seem to be fine but I am still having an issue with the answering machine and the voicemail fighting with each other. :/ I understand the voicemail being there, and I WANT it there to answer calls while ON the phone. I just don't understand why the answering machine gets a dial tone when answering and the caller is still getting a ring sound.

I have a thought and a question.
First, the question... Why do you need the answering machine at all if you're using GV voicemail? Why not let GV take all the messages?
Now, the thought... Is it possible the answering machine is essentially jiggling the switchhook (electrically speaking) in such a manner that it's putting the incoming call on hold so fast that the caller's carrier is never signaled that the phone has been answered, and then the Obi200 is giving the machine an outside line to make another call?
If you're not into tossing out your answering machine, or trying a different one, then I think you're going to need to make some adjustments on the Phone Port of the Obi200. I would have said to try a higher or lower Ringer Equivalence Number, except that's not a single setting on the Obi like it is on Grandstreams and some others. Maybe you can find guidance somewhere about how to emulate that with the settings the Obi has: Impedance, voltage, current, etc. Or maybe it could be fixed by some built-in feature you need to disable, like Conference calling.
Have a look at the Phone Port settings and see if you're inspired to play with any of them to see what happens.

@PropDad
You write of an answering machine. You also write that the phone is plugged directly into the OBi200. Unless you have a phone with built-in answering I don't understand. Please clarify.

Changing the OBi's REN is bunkum. There is no such adjustment on an OBi and no need for one. REN is a property of an FXO. A phone, a fax machine, an answering machine, the LINE port on an OBi 110, an OBi212 or an OBiLINE etc. It is a measure of how much power is required by the device to make its bell ring, its beeper beep, think about answering the call or whatever. A device that is supplying ringing has a finite limit on how much ringing power it can supply. Look at page 215 of https://www.obitalk.com/info/documents/admin_guide/OBiDeviceAdminGuide.pdf and you will see the OBi202 is specced as "Maximum Ring Load 5 REN (Ringer Equivalence Number)". There is no need to somehow reduce that capability if the total of the RENs of all the connected devices is less than 5.
A REN of 1 was typical of a traditional phone which used the ringing power sent by the phone company to directly operate the mechanical bell. Modern line-powered phones tend to use beepers which are more efficient than mechanical bells and have a REN less than 1. Mains powered devices (cordless base stations, answering machines, fax machines, OBi devices with LINE ports) need very little ringing power. They sense the ringing voltage and take very little ringing current. So again they have low REN figures.
