later I found this bug, http://jira.freeswitch.org/browse/FS-4023 I thought the short one worked and the long one didn't work, I was wrong. Actually my real problems was caused by that bug. the second tone spec I set didn't work. I'm still wondering what is the exactly length does a hit stand for. I'm also curious to know what do these two variables mean. I did some tests. I found that the hits doesn't mean the duration, a long tone doesn't hit more times. If a tone goes on and off, that will increase the hits number Thanks. On Tue, Mar 20, 2012 at 12:08 PM, Michael Collins <msc@freeswitch.org>wrote:
hits is what controls how "long" the tone needs to be present for the detection to be considered positive. The higher the number of hits, the longer the duration of the tone needs to be to form a positive detect. I would experiment with the hits value and see what you can learn.

Hi,
I just found that tone_detect worked sometimes and sometimes it didn't work. For a short length of tone like 100ms, it worked well. But for a much longer one (700ms or 1sec without pause), it didn't work. This one has not been detected but in the recording file, it was obvious.
by this wiki http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect I don't know how exactly the *hits* works.
And later I found these 2 variables called *tone_detect_sleep* and *tone_detect_expires. *But I didn't find any explanations about them. Can anybody bring more details?
Thanks.
