I am implementing a non-cisco voip solution on a cisco routing / switching infrastructure.
Our infrastructure is large. Voice traffic will travel across router(s) on our local lan.
QoS is currently not enabled in any way on our infrastructure.
Please provide examples / explain what configuration will need to be put on our cisco switches / routers in order to prioritize voice traffic as it travels from the access port, to the router, and back to the voip servers, etc.
I'm not looking for anything elaborate, only how to tag traffic coming in a port on a specific (voice) vlan and how to insure prioritization as it travels across the network.
