Being an ISP I have to disagree - ICMP traffic is rarely prioritized to "look better" Most large ISPs actually LIMIT ICMP traffic to counter ICMP flood DOS attacks. That does not make it a good indicator of a networks ability to support voip. Any cheap ATA will have jitter, delay, and packet loss counters - hook one up and get the real picture. If you do use ping to pre-qualify a link, grab a copy of pingplotter so you can tune the icmp packet parameters and packet rate, run it for a long time or several times during different timeframes to see if there are periods of congestion. _______________________________________________ --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
