For a few weeks now, completely randomly, maybe 2-3 times a week my landline will ring for 2 seconds then stop. A few minutes later it does the same thing again over and over until I unplug the phone. It has just happened less than 5 mins ago, previously it has done this at random times of the day, once at 5am. I dialed 1471 and got nothing but a crackly noise.
I see there are similar issues from others on here, what is going on?
