Several times a day, while a call is in progress, I get "zaptel Disabled echo canceller because of tone (rx) on channel X" and echo cancellation shuts off. I do use fax detection to route calls to my fax extension. It seems to have a 100% success rate. I heard a rumor about a patch that would disable echo cancellation after the first few seconds of the call. Is there such a thing? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20050607/86ac1e03/attachment.htm
