@Mmm19 Welcome to the Community. Which jack are you connecting to on the Ignite gateway? Only the "Tel 1" jack is active. Do you have a simple old-fashioned corded telephone that you can connect directly to the Ignite gateway to test with? If you do not get a dial tone, try restarting your Ignite gateway by power-cycling it.
