im using g729, but the bw usage is ~26 kbps per call, my gateways (cisco) support g723 and the bw between the gateways is ~18 kbps per call. Much better than the ~62 kbps of the g711. if you plan to be a voip provider you "must" go with compression codecs, especially if you want your customers to browse the internet while having a call. i.e. : We give voip phones (grandstream) to our VIP internet customers (512k - 1Mb bw), and create a tunnel (QoS) for voip traffic of 128 kbps, with compression codecs the customer can have 4 - 5 simultaneous calls, without compression codecs 2. BTW, i want to use only g723 but coudnt find licences for it, where can buy it in groups of 10 - 20 instead of 1000's ? Miguel

Effective monitoring of the traffic conditions may require a bit more work .. monitoring latencies, and maybe monitoring current utilizations via snmp on your core routers/switches/etc. A quick probe to the management interface would also give you some insight on current call volume, of course. -d _______________________________________________ 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 _______________________________________________ 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
