公司需要多少带宽托管pbx？
though the exact amount of bandwidth will depend on the number of users, the general rule of thumb for hosted pbx is 90 kilobits per second per caller. this means if you were on a call with three people on the same hosted pbx platform, you’d need 270 kilobits of bandwidth.
具有足够的带宽会影响呼叫的质量，可以防止抖动等常见的voip问题引起的抖动，延迟和回声差。
