string Monitors early media for failure conditions, such as a busy signal. This allows faster processing of failed calls when ignoring early media.

The syntax is a series of ! delimited early media conditions in the following format:


condition_nameuser defined name for the error condition
number_of_hitsthe number of times the tone must be heard before considering it a fail
tone_detect_frequenciesthe frequencies to listen for (delimited by + instead of ,). See tone_detect

(warning) this variable only works when ignore_early_media is set to true.
