Probably. I've found that it's not the absolute speed that matters, but the quality of your connectivity ISP that's as crucial. IN theory you can support 5 or 6 G711 calls over that link, but it will depend on your ISP, your router and what else you're doing on the link at the time. > Of course, I could figure out how to configure QOS in iptables for > asterisk, it'd be a lot better. A lot better to do it on your router, then it'll shape everything else on your LAN, although you can only effectively shape outgoing traffic, but this is usually enough given that outgoing speed is much less than incoming. (unless your router is linux, in which case google for wondershaper which is a good place to start) Gordon _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
