This doesn’t help me to solve my problem.
First I have to control the bandwidth on our Internet line and then I can think of QOS of the provider.
A little while ago I had the same feeling. But then I realized, that I can QoS SIP/RTP for all I wanted, but provider would just ignore my attempts and transfer all packets in the order received, thus negating any attempts at QoS on my side.
What are you trying to achieve? Prioritizing Voip traffic over HTTP?
This is what’s going to happen: someone on your LAN is downloading a file while you are trying to talk over your Voip phone. Your provider does not know about that. You configured ZS to prioritize Voip traffic, but provider is still flooding you with HTTP packets of that download. What do you want the router to do?
