mpd as a dial-in server

[Dmitry Tolstov]

  Hello,

I am trying to configure mpd-3.18_2 as a dial-in server with USR
Sportster voice modem. It works perfectly, but if connection dies
during authentication mpd says "waiting for ring" but keeps on
attempts:

and so on


When I try to redial mpd answers the phone and hangs up immediately.
