The bandwidth taken up by voice is really !pretty low; you can stuff a lot of voice signals on one line, but not !as many modem signals. I don't know exactly how much worse a modem is !than voice. Maybe one of you net.telecom heads knows? I think George is on target. many voice channels can be statistically multiplexed together since each has many intervals of silence. A modem connection is always making 'noise', so I believe that a modem connection will always be using the maximum allotted bandwidth of 8 KHz. Voice calls probably use 4 to 6 KHz on average.. (?) I'm going to forward this posting to comp.dcom.telecom. Come on over and check the group out. It's a good one! ...
