Hi! Mike, Thank you for your help resolving the cache files cleaning up issue we have. Now, I am having another question about the "terminators" attribute for playback tag. I did not see it in the online document and I did explore and plan to use it, but I am not sure it will be supported in the future. The book "FreeSwicth 1.2" did talk about it though. I would like to know that "terminators" will be kept as an attribute in the furture? Many Thanks! - Xiaoping ************* From online : https://freeswitch.org/confluence/display/FREESWITCH/mod_httapi <work>*ACTIONS*</work> <playback file name error-file action digit-timeout input-timeout loops asr-engine asr-grammar><bind action strip>*EXPR*</bind></playback> : Plays a file and optionally collects input.
