Why Isn't My Panasonic KX-TG6841 Phone Ringing for Incoming Calls?

It sounds like you're experiencing an issue with your Panasonic `KX-TG6841` cordless phone system where calls are going directly to voicemail instead of ringing through. Since your phone line is connected through Ooma, there are a few things we can check. First, ensure that your answering machine is turned on and that the number of rings is set appropriately. In your case, setting it to four rings is a good starting point. This way, if someone calls, they’ll have a chance to reach your answering machine before it goes to voicemail. If you've already reset your phone system and are still not hearing any rings when someone calls, it could indicate a problem with the line itself. You mentioned that you can hear a ringback tone when calling your number, which suggests that the call is reaching the line but not being processed correctly by your phone system. In this situation, it would be best to contact your phone service provider, Ooma, to investigate further. They may need to check the line to ensure everything is functioning properly on their end. Sometimes, issues like this can stem from the service provider rather than the phone system itself. Once you've spoken with them, let me know what they say, and we can explore further options if needed.
