I get sideband (interpreted by the enduser as echo) when calling a POTS line through our PRI on Snom's or X-Ten. Our crappy BudgeTones actually sound the best.
Everyone is exactly right here, that it really depends how the call is terminated on the other side. Calling from a Snom terminating to a PCS cell, for example, is crystal, no sideband at all. I'm assuming that the PCS carrier is doing their own echo cancel / sideband reduction. I dealt with my issues by simply cranking down the gain on the PRI (dramatically, I think I am at -15 Tx) . Every PRI from every carrier has different gain values; on my PRI, the carrier has it cranked to the max. Fiddling with gain values was, at least for me, the most effective way of eliminating the issue. _______________________________________________ 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
