Egad, this is just not true. 100 - 200 meters is for ETHERNET, not analog voice. I have many runs over 1K meters that work just fine, and several that are close to 3Km that honestly do NOT. Think about high rise buildings - many strung with CAT3 cable for voice from the basement. Many of those runs may be well over 1000m. A better question is why is he stuck using a 3Km leased circuit? Like another poster said "there must be a better way". j _______________________________________________ -- 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
