Sorry, forgot to include the DAHDI version. voyage:~# dahdi_cfg -tv DAHDI Tools Version - 2.2.1 DAHDI Version: 2.2.1 Echo Canceller(s): Configuration ====================== I'm almost sure this board's RTC is not very accurate. Is there any way to measure the RTC's accuracy? -- _____________________________________________________________________ -- 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
