One thing that many PSTN providers are doing for calls when they went
digital is to insert small quantities of noise into the line.  That way
people do not think they are disconnected.  There is a bunch of
documentation on this, and even some that applies to VoIP
providers/equipment doing the same (its basically a faint bit of white
noise so you hear *something*).
