I do not know what this all means. My telephone still works. However, on Dashboard the code changed from 401 to 400. One thing I noticed is that I must dial "1" and area code before putting my calls through. Just now, in order to test my 911 calling ability, I dialed "933" and got an error message saying that the service provider could not place the call. The reason given was code 603. From our initial post I thought that "screwing around" inside a router was an unreasonable solution. Now, since beginning this post this morning, and since submitting that huge order to VOIPo yesterday, wait until you hear what nonsense they just gave me over the telephone. From what they said, I feel like cancelling the order I placed with them. After I ended the call, I shot them an email. The technician would not provide anything to help me adjust these settings. He told me to wait for their adapter, which will take 7 to 10 days to arrive. I don't care if it arrived now. After refusing my ISP's requirement to swap devices, in their case cable modems, I am not going to swap my OBi202 after long setup for something they provide. From their site they are in league with Grandstream and Linksys. Especially after establishing a wireless connection with my OBi device through your OBiWIFI5G adapter, in this case I am not going to swap out VOIP devices. My desire for Internet telephone connection is turning really nasty. It is only moments later that I got a response from VOIPo. It is practically an invitation to cancel. They say there requirement that we use their ATA adapter is a "fraud preventative measure." It does not prevent them from committing fraud. Now I am "out of luck;" and I thought I was going to wrap this all up today after being without phone service since January 16, 2019.
