Unfortunatelly good-old Windows based ping is all I can work with before I actually sign the contract with the ISP. I need to assess rather the service might be possible before I start throwing money at it (there's no such thing as an "test account": I'll need to set up an account, pay the instalation fees, pay one month in advance for the service then pay for the disconnect!). Sooo... what might I find using ping? Is there an "good" ping that shows I can use the link for VoIP? I gues there's no such thing as "bad" ping showing I can't use the link because ISP's are limiting ICMP traffic? _______________________________________________ --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
