There should be *NO* reason to adjust tx/rxgain on a PRI or ANY digital connection! The fact that adjusting it down 10% worked suggests that the telco switch is boosting the signal for some unknown reason. Use the technique outlined in this message: http://lists.digium.com/pipermail/asterisk-users/2004-November/071301.html (It works VERY well and is very straightforward, thank you Kris, I reference this all the time!) Again if you're screwing with gains on PRI you have bigger problems, I think. -A. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
