Question

What is minimum acceptable data rate required for Skype call?

Answer 1

For making a uninterrupted call on skype, high speed internet connection is preferred. In case of minimum acceptable data rate, I think 512kbps would be sufficient. Below that rate you can face some delay during the call and quality of the call will also be low.

Answer 2

According to Skype Support, if you signed to Skype without making calls, Skype will use on average 0-4Kbps. When you make a call, skype will use on average between 24-128Kbps.
