My vtech phone says home line in use and I'm getting no dial tone,just a crackling sound.All the phones are on the hook and hung up.The link and phone light on my modem are flashing(touchtone telephony modem).I have reset the modem and taken out and pluggged the phone line back in,but it doesn't seem to help.
That normally indicates a inside wiring short or fault. Unplug the cord from the eMTA telephony modem and connect a good wired phone directly to the L1/L2 jack on the eMTA. Give it a test. You might need to reset the eMTA by pressing the small indented button on the panel where the cables attach for 10 seconds.
If it works with the phone connected directly, then you need to troubleshoot or hire someone to troubleshoot your inside telephone wiring in the home. It can be a shorted wire where everything is spliced together, a corrorded jack, short in the jack, a bad phone cable on any of your telephones the home, or even shorts caused by animals & rodents on the outside, under the home. Unplug all phones to start troubleshooting.
You can try to troubleshoot yourself, hire a local low voltage contractor or hire Comcast. Because the inside phone wiring is owned by the homeowner like the electrical & plumbing, you would bear the cost of repairs.

Ok I found out the problem.There was a phone cord plugged into the outlet in the bedroom with no phone attached (we just got new phones and didn't put one in that room)Now I feel stupid for posting this,hahaha.Check to make sure all your phones are correctly hooked up.
