Hi Tilghman, I thought I had found something, all of the lines were patched in with Cat 5 patch cords except Port 16 which had a telephone cable (which would flip the polarity). After changing all the patch cables to telephone type, I re-ran fxotune but the results were almost identical to the original settings. new fxotune.conf:- 13=7,255,251,251,2,255,255,1,255 14=9,254,251,255,2,0,1,0,0 15=6,1,254,253,0,255,0,0,0 16=5,0,0,0,0,0,0,0,0 17=9,254,251,255,2,0,1,0,0 18=9,254,251,255,2,0,1,0,0 19=9,254,251,255,2,0,1,0,0 20=7,255,251,251,2,255,255,1,255 21=9,254,251,255,2,0,1,0,0 22=9,254,251,255,2,0,1,0,0 23=6,1,254,253,0,255,0,0,0 24=9,254,251,255,2,0,1,0,0 These results are very similar to John Morey's, eg. not much changed after reversing polarity. The one line that shows zero's all the way across is the line with our DSL backup line on it. Is it the filter giving these results or does the telco take more care balancing lines for DSL? Shouldn't I have seen a major change of settings after changing polarity for tip&ring? regards, Drew -- Drew Gibson Systems Administrator OANDA Corporation www.oanda.com _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
