There's definitely something changing on the phone network recently, and I can't quite work it out, you know how when you ring somewhere with a switchboard, before you get answered you get the normal ringtone in your earpiece, then when they answer it changes. You ask to be put through to say extension 12, and while you are waiting, you still hear a ringing sound, but in some way it seems harsher, more growly. Well recently I've made a few calls and if they take a long time answering, the ringtone goes growly, not a fault, just like it's been switched somehow, very odd.
