Configuring Voice VLAN
The device includes a VLAN tag configured in the voice VLAN in SIP, RTP and T.38 data packets.
The voice VLAN of the device has the following two modes: Mode 1 and Mode 2.
Mode1 - Signaling (SIP) and media stream (RTP/T.38) are on the same VLAN
In this mode, the voice VLAN can be configured with a separate IP address.
On the web interface, click Network, and ensure that the VLAN function is set to On and Mode is
set to Multi-service VLAN. Select Mode 1 for Voice VLAN, enter the VLAN tag, and specify
network information such as IP address.

Mode2 - Signaling (SIP) and media stream (RTP/T.38) are divided into different VLANs
In this mode, the voice VLAN cannot be configured with a separate address but shares the IP
address of the VLAN interface of the device.
