We are getting ready to install a mitel voip phone system on our Cisco network. We have been doing some research on how to configure our 4006 layer3 switch but have not found anything that states which config is better over another. From what we've found we should create an auxiliary vlan, set qos(doc refers as cos?) and the document offers different options for the packets (dot1, untagged, etc) Could someone offer a good suggestion which way to setup the vlan on our 4006 for the ip phones.
thank you in advance,
