You can resolve these issues by isolating the voice traffic onto a separate VLAN. The switch port that the
phone connects to would be configured to have separate VLANs for carrying:
• Voice traffic to and from the IP Phone (auxiliary VLAN on the Cisco Catalyst 6000 series, for example)
• Data traffic to and from the PC connected to the switch through the access port of the IP Phone (native
Isolating the phones on a separate, auxiliary VLAN increases the quality of the voice traffic and allows a large
number of phones to be added to an existing network when there are not enough IP addresses for each phone.
