When creating a voice and a data vlan on a switch port for an IP phone and a computer which connected to the phone, do the phone and the computer need to be on different subnet or they can be on the same one? For example, do I have to put the phone on 192.168.1.x/24 while the computer on 192.168.2.x/24, or they both can stay at 192.168.1.x/24? Thanks. |

Allows you to place an ACL on traffic to/from VoIP subnet.
If subnet is also on a different VLAN, may restrict the number of packets (e.g. broadcast) seen by the VoIP device's NIC. Also may allow the VoIP device's NIC to filter received packets to just those on its VLAN.

Phones and data can work on the same subnet/VLAN.

Hi Joseph,
What is the advantage of putting data and voice on different subnet?
