For a couple of days, we've found our phone was acting a bit flaky. This seemed odd because we've had great service from our Ooma Telo for over three years. We've saved a tremendous amount of money by getting rid of the landline. However, our Ooma lets us keep a flexible, British Columbian, home phone number.I wondered if the device was developing a hardware problem. The online blue light was fine. I went to my Telo Dashboard and it indicated the device was online too. We had a dial tone, but, after dialling a majority of phone numbers, we'd hear nothing! I could both send and receive calls to my cell phone though.
I clicked on the online chat button and a representative was with me almost immediately. She suggested it was a problem with my router/modem ports and protocols.
Then, I remembered tinkering with my modem settings through its http://192.168.0.1/ admin page. I often check to verify the dozens of connections made by my wifi smart home devices.
I reset a few parameters, and my telephone service is back to normal.
I am so happy I have enough junk to keep me occupied. I continue to learn technical minutiae most every day.
