[Asterisk-Users] Do we need a QOS switch ?
Hi, We have 10 people on our network and each person will have a SIP phone connected to our Asterisk server. All phones, Asterisk, other servers and users workstations will be using the same network. The question is: would I need a QOS device to give SIP traffic a chance? Our internal network is 100M. We will have a ISDN30 for outgoing calls. No calls will be made over the internet. Thank you in advance!

I assume you will make up to 10 simultaneous calls, so you can calculate the bandwidth you'll be using. (http://www.voip-info.org/wiki/view/Bandwidth+consumption) When using the G.711 codec, it'll be about 1.5-2Mbps when doing 10 simultaneous calls. If you don't overload your internal network, you'll be fine.. cheers ___ --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

The proposed VOIP traffic will have little impact on the usability of their network FOR VOIP traffic. It is all the other stuff that runs across their LAN that make make VOIP "a really cappy idea", if the don't take steps to ensure that the VOIP traffic is managed properly. With the paucity of details provide by the OP, it is impossible to say, with any degree of credibility, that the "...will be fine..." Do those 10 phone sit on the desks of graphic designers, whose file and print traffic can bring a 100 Mbps segment to its knees? ___ --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

In other words, all the users' PCs are hooked into their phone, so any excessive traffic does not interfere with the phone. Since the phones then hook directly into the same switch that the PBX (Asterisk) hangs off, quality has been fine. Keep in mind this is for small offices like you describe. Provided the topology of your switches is OK, you should be fine. Just don't uplink to another switch where you can create a non-QoSd bottleneck link. -Ron ___ --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
