During the playback of the file, audio is monitored in the receive direction, and if a period of non-silence which is greater than min ms yet less than max ms is followed by silence for at least sil ms, which occurs during the first analysistime ms, then the audio playback is aborted and processing jumps to the talk extension, if available. ### Syntax
    BackgroundDetect(filename,sil,min,max,analysistime)
##### Arguments `filename` `sil` - If not specified, defaults to `1000`. `min` - If not specified, defaults to `100`. `max` - If not specified, defaults to `infinity`. `analysistime` - If not specified, defaults to `infinity`. ### Import Version This documentation was imported from Asterisk Version SVN-trunk-r370328
