How would you help a Comcast customer with no dial tone on their home phone?

"If a customer had no dial tone, the very first thing I would check is if there were any reported outages in their area. I would then ask them to double check that there are no phones off the hook in the home. Next, I would ask them to make sure all cables were properly connected. Lastly, if the customer had a cordless telephone, I would ask them to change the battery or hang the phone up to get a fresh charge. Generally speaking, these are the primary culprits to the no dial tone issue."
