How can I use a Layer 3 switch for voice routing?

Learn how to use a Layer 3 switch for voice routing in this expert response from a switch expert.

Can a Layer 3 switch be used for voice routing? How?
Yes you can. Voice is treated as data with real time QoS parameters. If you have configured QOS correctly it will treat the packet on high priority and route it.

If you are referring to call routing as call processing, it can do only if IOS supports it.
