I had a modem for my Cox services (wifi and voice) for about 5 years. It died and I "upgraded" to a panoramic wifi gateway (model CGM4140COM). The only change was switching out the devices. When I try to use the phone, there is no dial tone. I checked all the physical connections, the cord from the phone to TEL 1 port, the wifi works, but the voice service with my phone does not work. I can view the missed calls online in my account data though. I reviewed the troubleshooting steps listed online and used the online assistant, to no avail. They scheduled a tech to check it out, but I'd prefer to fix it before that occurs. Any ideas on what it could be?
It's probably not provisioned for telephone. Call and ask to be provisioned.
