No Dial Tone

I had same issue after receiving new modem equipment.  Call xfinity directly. I got yanked around with AI assistance. Zero help. I was then told that my "landline" phone number associated with account was not "registered " under new modem. The customer service rep then fixed issue. Problem was resolved in 5 minutes. Who knew the landlines needed to be re-added to new equipment.  Good luck. 

Hey there, kjrtoday! Thanks for posting on our XFINITY Community Forum as well. I wanted to ask if you have had a chance to try the troubleshooting resolution steps from our community here on this thread. Please let us know if you require any further assistance.

Hey All - I think I found the solution... after attempting to contact Xfinity multiple times (> 15) via in-store visit (resulted in a new modem being issued unnecessarily), phone, and Chat, I tried a couple of different approaches to solve this... 1) After a "Google" search regarding XG8 No dial tone issues, there was suggestion of 'provisioning" being necessary by a Tier II representative.  This was not known by the customer service at the store and apparently not by the salesperson who set up our new service over the phone. 2) I changed the way I was troubleshooting and interacting with the Xfinity Chat tool since we can all agree just puts us into an endless not-helpful infinite loop if we type "No Dial Tone".  Once I typed in "Technician", with all the warnings of a charge for service, I was able to schedule an appointment knowing full well that this was a software issue, but at least I could talk to a technician.   We received a phone call within an hour from an Xfinity 800 number after we requested through the chat that a technician be sent.  Using the keyword "Technician" was the only approach that allowed me to exit the loop within the Xfinity Assistant.  That was the greatest challenge... simply getting a live person from Xfinity to pick up the phone as the current taxonomy in the chat appears to be unable to exit when the key word "No Dial Tone" is entered.

The root problem is that upgrading from the XB7 to XB8 requires the phone number to be re-provisioned and a software engineer has to rebuild the switch probably get added to some SQL database consuming numbers exclusive to the XB8.  I ended up getting a new phone number assigned, then asked to have my old phone number back which they did do seamlessly.  Also, I should have noticed that "Phone" had dropped from my Xfinity app options and is now back.
