For various reasons I'm keeping my landline.
About 10 years ago someone digging near me cut a major trunk cable-knocked out service to 50,000 customers. AT&T did a hurry up job of splicing and it wasn't done right.
About every 5 months or so, either my phone would get a loud hum and I couldn't break dial tone, my DSL would drop, or both.
Call their 800# and wade through the options until you finally get someone in India reading from a script. "I already did all that BEFORE I called you. That's why I called you"
Usually somehow by 5 PM it would start working again. Each time AT&T would threaten to send someone out and check my house wiring and charge me big $ if it was me instead of them.
I would say go ahead. After about 4 years of this, finally one day there's a knock on the door.
The rep checks the wiring and says there's nothing wrong with your house wiring-it's perfect. Then he added that he noticed I used Cat 6 cable to wire the phone lines.
I told him that when I rewired I used the cable since it had multiple shielded pairs since I also set up my VOIP phone around the house. He nodded and said that was a good idea.
He then went on up the street to the local junction box, came back after about 10 minutes and said no problem between there and the house so it had to be up the line somewhere.
I told them that I bet the problem was up the road where the trunk had been cut and his comment was that I was probably right.
About an hour later he came back and said check it now. The phone line was clear without a trace of any kind of noise and my DSL speed was about 20% faster than it had ever been before.
I said thanks and he smiled and said "I found you a GOOD pair of wires."
It's been about 5 years now and I haven't had any problems since.
BUt since every month there's a new fee or price increase on my internet service I'm dumping them.
