XB10 Voice (landline) Connection

Is there anyone using the new Xfinity XB10 modem and also using its voice, not cell phone, connection?

I have the XB10 modem. It is set up and has a non flashing white front panel light. I have a good Internet connection and can surf the Internet. However, as much as I have tried, I cannot make its voice connection work.

I have no dial tone, it is dead. I have done a number of resets, including a total reset. I spent 40 minutes on my cell phone with Maria in the Philippines. I visited to two different Xfinity local stores. I have tried three different XB10 modems. All work correctly, except the voice connection.

I can remove the XB10 modem and reconnect my older modem (XB8-T). Using that modem, it functions correctly, including the voice connection. It appears that the my next need is to have an Xfinity technician come to my home.

I am beginning to think that the XB10 modem needs a firmware upgrade.

Good evening Autumn_Color, thanks so much for taking the time to reach us here via our Xfinity Forums! Is this still a concern for you? Based on your description, it sounds like the new XB10 may not have activated fully with the changeover. And when you are plugging this into the XB10, are we using the correct port to plug into? (should be Port 1) On the internet side, do things seem stable with the service?

Thank you for your reply. I am using the correct port 1 for this phone connection. It is still not working.

When I was on my cell phone with the lady in the Philippines, she said that she was provisioning my system. It could take 72 hours to take place. It did not help with the voice phone problem.

On the internet side, it is working. The Ookla speed test just showed about 1700 Mbps upload and about 300 Mbps download. For what I am paying, it should show higher, but I know it can vary.
