What should be minimum bandwidth

I want to use video conferencing feature that is provided by my VoIP service provider. The problem is video quality is not very good. My service provider suggested me to have more bandwidth. I want to know how much minimum bandwidth is required for VoIP video calls.

The best way is to ask your VoIP service provider the required bandwidth in terms of internet speed and then either get that upgraded from your internet service provider or get a service from a better ISP.

You should get at least 1 mb bandwidth for your VoIP service. That way, you will be able to make calls and enjoy browsing simultaneously.
