Before I start then a couple of questions. 1. What is a WAN? 2. What is a LAN? 3. Which one of the above do carriers build? 4. Do they use LOTS of hubs and LAN switches to do this? First respondent with the right answers on a postcard will make lots of money out of carefully selected networking stocks.

CISCO IOS is a run to completion OS. All voice products (so far I have heard) cannot provide latency guarantee. If you take a 20 hop network with 1 million phone calls, compute intensive data network route calculation(In parallel), HTTP traffic, FTP Traffic, 7500 will come to knee (with respect to voice calls). THIS IS NOT ACCEPTABLE FOR A COMMON USER, especially phone calls which has to be real time. Routers crash often enough when compared to TDM switches. This philosophy also apply to LAN switches (collision domain). Voice has to be guaranteed and you cannot drop voice packets which got digitized.
