My landline has no dial tone at the outside junction box. However, when I plug a phone into the voice modem (Arris TM722) I get a dial tone. I can then dial out, but the line won't receive incoming calls.
I can see an incoming call number siplayed on the TV, and the voice-mail records messages.
What's going on?
I can call my cell phone with a phone handset plugged into the Line 1 jack on the back of the modem. I can call the landline number from my cell phone, but it doesn't ring the handset and eventually goes to voice mail.
The last time I had this problem the tech told me to check for a dial tone at the outside customer service box where the line comes from the pole. There was no dial tone there, so he went up the pole that the phone line was fed from, jiggered some wiring, and I got my service back.
