For literally YEARS, we have not had a well-functioning landline at home. If we desperately needed a 911 call, it would've been a 50/50 shot whether the operator could hear us over the static. In our old house, it was caused by a lightning strike to the roof of our home. In our current place, it was because of ... I don't know. Just one more thing that those swell dudes left for us, bless their hearts.
This was starting to piss me off. I called India, I mean ATT, and they said they'd do a diagnostic on our line. If it was due to factors inside our home, it was our fault and they'd charge us $70 and call us names. ATT has such great service. They did the diagnostic and never called us back or told us the result (and, fortunately never charged us). But, the line still sucked. I finally nearly attacked a service guy outside our home doing another job and complained. He gave me a card of someone to call - in this country. Two weeks later, our line is static-free. Crystal clear!! And, it was on the outside of the house, no charge. Hooray! So, family, friends, you can now leave a message and we'll actually get it.
