I have a scenario of a network with about 1000 voip phones.
I need to configure QOS for the voip.
The equipment I have are various 9702E, 6450, 6250 and 6248.
I have part of the voice routed to different sites.
You could explain to me which is the best option to apply QOS. DSCP ?, trusted phones options ? others ?
I just need a little the concept to start.
Thanks
