Question

I am trying to call a land line, but it rings funny. 2 rings, then silence then a busy signal. Any clues why?

Answer 1

Short answer:  Something ain't workin'!

Long answer:  There is a fault in one of several places; the phone itself, the wireing in the house, or somewhere in the phone system outside of the home.

Sorry I can't be more specific. There are a lot of possible causes!

Answer 2

It could be a fault, or it might even be a call diverter which answers the call after a couple of rings and then dials out a different number on another line.   If the number that it dials is busy (either because it's genuinely busy or due to a fault on THAT line), that would account for the rings followed by a busy signal.
