Thanks!

For what it's worth, I've used voip internet phone service on "DIAL-UP" service and it worked fine.

Now, when dealing with true data, such as file transfers, downloading, etc... the bandwidth is the key. While the bandwidth itself isn't speed, the more bandwidth you have, the more data you can process at one time, thus the faster you can go from beginning to end. Voice on the other hand is LIVE. If it takes you 15 seconds to speak a paragraph, then it takes the same amount of time to get that message across whether you have 15mb bandwidth on cable or 1.5mb on DSL. Basically; if you weren't doing any other computer work, and just talking on the phone, then 1.5mb DSL is more than enough. It's better to have more bandwidth so you can do other things at the same times.

But it's the latency, and more important "Jitter" (The Difference between the low and high in latency), that is the biggest factor in successful or poor quality voip. But to answer the question, the 15mb is more than enough. Assuming you have less than 150ms of latency. That's usually the high end when voip starts having problems. Remember; you're talking. Not sending normal data. You CAN'T RESEND a voice packet. The conversation has already moved on. And if the latency is too high, you'll end up talking over each other. FWIW: Voip, at it's highest codec level G.711, only uses around 90kb of bandwidth up and down. With g.729 codec, it only uses around 25kb of bandwidth. (That's why it worked fine on dialup). later... mike....

The poster said she or he isn't good with technical data and you gave him or her a pedantic dissertation!

Basic simple answer: It should be perfectly fine. The amount of bandwidth you will be getting is way more than enough and will be at least as good as your previous internet provider and probably more than 90% of other users.
