Configuring the Type of Service (ToS) priority
To configure the IP Type of Service (ToS) byte for UDP voice packets:
1 Open the Ethernet > Mod Config > VOIP Options menu.
2 Set the TOS Enabled parameter by pressing Enter to toggle between Yes and No,
enabling or disabling the ToS byte configuration. For Example:
Ethernet
Mod Config
TOS Enabled=Yes
This parameter defaults to Yes. If this parameter is changed to No, MultiVoice will
request the network’s default processing priority for UDP voice packets.
