To my ear, ILBC sounds much better than GSM. It's slightly more efficient, and more tolerant of things like packet loss. Some folks, hate the sound of ILBC encoded calls. <shrug> Your other choice would be G.726/32. * supports it, as do many ATA's and softphones. It's a bit fatter, but sounds MUCH better than GSM. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
