Echo cancellation in hardware is just as hard as software. Difference is, smart people already wrote proper echo cancelling algorithms, but they aren't releasing them, and they are only available in hardware. :(
(Yes, DSPs make hardware implementations *somewhat* simpler, but not significantly) Sourcecode license for a proper g.168 echocan runs in ~50k$ range plus royalties. :( -alex _______________________________________________ Asterisk-Biz mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-biz
