Hi, I have an asterisk 1.2.1 on a debian box with a tdm400p card and a monoBRI card. I tryed to use fxotune: turned off asterisk leaving modules active as seen from lsmod: zaptel 224132 1 wctdm crc_ccitt 2432 1 zaptel I launched fxotune: *pbxtest:/etc/asterisk# /usr/src/zaptel-1.2.1/fxotune -i 4* but fxotune displays these messages: *Tuning module 1Skipping non-TDM / non-FXO Failure! Could not fill input buffer Tuning module 2Failure!* What does they mean?? TIA Giorgio Incantalupo
