monitor_early_media_ring

string Monitors early media for a user-specific ring tone. Each time the tone is heard, the switch will increment an internal counter for that leg. Once the counter reaches monitor_early_media_ring_total (or this variable has not been set) then the early media will be sent.

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

condition_name:number_of_hits:tone_detect_frequencies

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

this variable only works when ignore_early_media is set to true.

Usage
