Busy signal

A busy signal (or busy tone or engaged tone) in telephony is an audible or visual signal to the calling party that indicates failure to complete the requested connection of that particular telephone call.

The busy signal has become less common in the past decade due to the prevalence of call waiting and voice mail.

Reasons for a busy signal

An otherwise unspecified busy signal indicates that the called number is occupied:

The standard busy signal sometimes occurs (sometimes with an intercept message played over the busy) at the end of a call to indicate the other party has hung up, but mostly the Off-hook tone is used.

Reorder tone

A reorder tone, sometimes called a fast busy signal, indicates that no transmission path to the called number is available. This is usually because the Inter-LATA trunk is busy at the time of the call. Usually, this clears in a few seconds, if one redials.
