I mean - when your system check on hook tone (unchecked item "No detect on hook tone") - parameters for on hook tone decleared in "system/tone detector - on hook tone". If one your PBX works fine and next one no - check what decleared in your PBX's.

hi
you should change the digits(start 20 up to 80 )to find your answer.
don't forget ,sometime if you set 20 the lines cut off between conversation.
