(note: inband) i actually went through the whole process of tracking down which switches had down right bad recordings back in 2004, and was able to get them to re-record (or fix) the SIT's. after the first round of fixes, i provided another batch of like 150+, and at that point they would not fix anymore. so, goodluck with 'precise SIT detection' (inband) the below link is data on the tests and such, even a couple screenshots showing the difference in amplitude from a mere whisper, to near eardrum damage levels. http://www.dynx.net/SBC/ (this is why conversion to PRI (for outofband info) is the path we took) ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
