I have been using Obi phones and adapters for close to 10 years, if not more.
For months now, non of my ** options seem to work. I can't dial AA or AA2 (**0, ***). I can't dial other obi phones through the obi service, which I used to do quite regularly. I am getting the annoying series of beeps that you get when you dial the wrong number.
Is there something recent that I need to be aware of?
