I don't know what caused this to break in the first place or what happened to make it work again. At this moment, I'm just happy that people hear the phone ring when they call my house.
Should I be worried that this will happen again in the future? I don't know. Keeping my fingers crossed that it won't.
I don't check this forum very often. This is the first problem I've had with OOMA. If you do have this problem in the future, please let me know at my email at firstname.lastname@example.org.
