<<please advise why the pure Layer 3 routing capabilities of the 7000s are inadequate for VoIP. >> The routing capabilities of 7000s are obviously the best in the industry and work well for any traffic type, provided the unit does not get bogged down supporting an inefficient mix of protocols. (For example direct support of SDLC, IP, and IS-IS will vacuum 7000 processor cycles and result in slower performance.) But that was not my point. It has not been proven that these units are capable of handling any scale of voice traffic with predictable latency. Remember, with voice, we need not only short delays, but predictable ones as well. This is the challenge when integrating legacy routers into newer networks. I would place my bet with large facilities base ISPs before betting on some kind of consortium. Bill
