Modem problem, provided that the ATX parameter is set to require dial
tone.

Failing to break dial tone is a modem (dial tone too weak) or phone
system (presenting dial tone when there is no dial tone decoder available)
fault.

Software configuration problems that might just cause this:

- non-standard ATX settings which disable dial tone detect, but any
  tone sent after the tone starts should break it;

- configuring tone dialing on a pulse only line;

- not overriding the pulse length when using a modem not designed for
  the network in use.
