5.1.2 Multi-service VLAN

In the multi-service VLAN mode, the TGW can configure a VLAN tag; a priority for the voice service
(SIP signaling and RTP/T.38 media stream); and a management service (HTTP, Telnet, TR069, and
SNMP). The TGW carries a different VLAN tag in data packets for different services. In this mode, the
physical network port of the TGW can have a separate address or obtain an address from a non-VLAN
network.
Configuring Voice VLAN
The TGW includes a VLAN tag configured in the voice VLAN in SIP, RTP and T.38 data packets.
The voice VLAN of the TGW 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 TGW.
