We have some Cisco switches - WS-C2960S-48LPS-L
We got these specifically for when we upgrade our phone system to Voip.
Now I've had some potential supplier in today re. Voip and they have told us that these switches are no good re. QoS and we need to replace them with some Layer3 switches.
I thought these switches were fine for Cisco based phones?
Are they correct or talking a load of **** ?
