Phone connected to xFi router-modem has no dial tone.
I have the X1 Triple Play package. I changed from a 5 year old Arris TG1682T to a Arris TG3482G xFI Gateway a few days ago. The setup was simple; internet is great. Today I went to use the phone. There is no dial tone; the handset display shows "no line." Neither jack works. No clue in the xFi app as to configuration. Can someone help? TIA.
