I have similar settings in my fxotune.conf for a TDM2400P and I'm getting complaints of "static" on the line that I suspect are related to an overtaxed h/w echo canceller My fxotune.conf:- 13=7,255,251,251,2,255,255,1,255 14=9,254,251,255,2,0,1,0,0 15=9,254,251,255,2,0,1,0,0 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=9,254,251,255,2,0,1,0,0 21=9,254,251,255,2,0,1,0,0 22=9,254,251,255,2,0,1,0,0 23=9,254,251,255,2,0,1,0,0 24=9,254,251,255,2,0,1,0,0 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
