Hi folks. First of all, please excuse the basic nature of this question! We are a company experiencing VOIP issues on our network. QoS is enabled for VOIP traffic. However I'm wondering if the topology is different to others out there. My understanding is that QoS is set on the traffic going out of a switch. Looking at what happens afterwards, if loads of traffic from different sites arrives in one central node, the QoS is not configured to work at the incoming point of view so performance will be poor at this point. In that case the problem would be generic so I now wonder if the successful VOIP implementations out there have an entirely separate network used for VOIP? Or am I missing something?
This is the forum for the WX (WAN Acceleration). Please let us know, if this is related with WX or any other Juniper product? If its not WX, i suggest you to post this question to the appropriate Juniper product forum.
I can just fill out with a little part of the question but I work a lot with VoIP related stuff.
Normally you run VoIP in the same network as the data traffic otherwise you dont get a multiservice network and there not so big point to migrate to VoIP, this is the most common solution I have seen. In some rare case I have seen a hard separation of voice but that was a result of bad/time saving engineeering(dont think just do it the safe way).
I have a theory that if you have a very bad network and bandwidht Detection enabled the back off function will affect your voice traffic badly, not the WC's fault but thats the result of the function.
