VoIP is usually a seperate VLAN so we should be able to create a trend and some custom traffic reports similiar to WAN subnet. If you drill down to a flows report you see the conversations between the VoIP phones and the VoIP server.

Traffic Report - Select the Bandwidth \ IP \ Traffic Distribution report. Enter in the subnet(s) assigned to the remote site and then click the View button.

Trend - To add a custom trend select Modules / Trends / Configuration. Then click on add new trend. You need to set the following variables:
- Title: This is just a name for a trend.
- Select a Sensor: You need to select the LANGuardian sensor which is collecting data for the VoIP VLAN.
- Subnet: As with previous reports you need to enter the subnet(s) associated with the VoIP VLAN.
- Template: By selecting total traffic you will get a graph with a single line showing total traffic to/from the VoIP VLAN. If you select subnet traffic you will get two lines on the graph. One for traffic outbound to the VoIP VLAN and one for inbound traffic from the VoIP VLAN.
