I don't know about you, but my obihai has not failed more than once since this pandemic broke out. So it's been almost 5 weeks and I've only had to reset it once the entire time. I still have the same amount of phone calls every day since I use it as my main landline. Multiple hourly conference calls all throughout the day. No problems.
we should all take heed on this notion, because I am fairly certain that there is foul play at hand with the issues that we have been experiencing. Something, somewhere, somehow has been implementing a deliberate reduction in phone line experience on these little boxes, which is clearly not present during this time, perhaps because someone told whomever is doing this to stand-down during the pandemic.
I may be overthinking it, but reality is that I have not had to reset the unit almost at all.
