voip电话服务比pstn线更安全吗？
这取决于。即使使用模拟pstn接线，犯罪分子也通过电线使用物理访问和窃听到您的对话中进行线路。使用voip，如果您采取正确的步骤，如加密和使用专用网络作为voip骨架，则黑客几乎没有违反您的安全性。
this depends on the security measures in place on the ports. more ports mean that you have to employ more voip security measures when protecting your voip system. for this reason, your team needs to use the minimum number of ports so that there are fewer entry points into your voip network to protect. it’s also essential to plan implementation before you install any new voip infrastructure.
