Can someone tell me what it means when I dial someone's number from my Android phone (a Samsung Galaxy A3, in case it's relevant) and the call disconnects almost immediately, after a short, descending 'biddly-boop' tone? There is no 'ringing at the other end' tone or 'engaged' tone to indicate what's happening.
I've Googled this, but the only hits I'm getting are to do with the 'engaged' behaviour of Android phones themselves, not what's happening to calls made from an Android phone. I've noticed it with two land line numbers which I've dialled recently, and in the case of the latest one it's mildly urgent that I contact the person.
Thanks in advance for any help/feedback.

Oh, sure, I love technology and embrace it, but there are certain 'old' things I miss. I often wonder why such-and-such can't/won't do what I think it should.
It's my go-to phone, the only number I ever give out. Only my closest friends and relatives even know my cell number--but they know never to call it unless they've been unable, for awhile, to reach me otherwise. I simply don't use it. [Well, as a phone--I'm typing this on it, over Wi-Fi.]
