What about G.723.1? Anybody have any experiece with this? I know I can order the documentation (including C source) from the ITU, what does this entitle me to do? Are there any licencing gotcha's to going with this approach?

G729 is currently not available due to patent and license issues. You will find that G711 is fine on a local network, and asterisk does real well using IAX protocol and GSM codec. So if you are deploying enough phones to make it worth while to drop a * machine on the LAN with the hardphones you are set. Otherwise you might want to look at the Snom phone since it supports GSM. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
