Example setup - Overview

Last Updated : Jul 06, 2021 |

The network is devised to allow the user PC to connect to the switch port of the IP Phone. A single cable then connects PC and IP Phone to the Ethernet Switch. For the purpose of this example, VLAN 100 is used for voice traffic and VLAN 101 is used for data traffic. The LAN1 interface of the IP Office control unit resides on the voice VLAN while the LAN2 interface resides in the data VLAN. Communication between the voice and data VLANs is facilitated by the IP Office control unit's router function.
