Landline has no dial tone

I upgraded to an xFi Advanced Gateway today. Now my landline is dead (no live connection). I have a Panasonic Bluetooth® Cordless Phone connected to the landline phone jack. This setup worked perfectly before the upgrade. What should I do?

Try to activate again or have customer service do it.
