ProSafe M4100 and M7100 Managed Switches
In a VoIP system, various signaling protocols are used to establish the connection between
two VoIP devices. The supported signaling protocols are SIP, H.323, and SCCP.
OUI-based Auto VoIP
The OUI-based Auto VoIP feature prioritizes VoIP packets based on the OUI bytes in the
source MAC address.
A default list of OUIs is maintained. User is also allowed to configure
OUIs that need prioritization apart from the default OUI list. Up to 128 OUIs are allowed on
the device or system, including the default OUIs.
Note: If voice VLAN and Auto-VoIP are enabled at the same time, one of
them is operational. If the connected phone is LLDP-MED capable,
voice VLAN has precedence over the Auto VoIP and Auto VoIP is
operational if the phone does not support LLDP-MED.
auto-voip {protocol-based | oui-based}
This command is used to configure auto VoIP mode. The supported modes are
protocol-based and oui-based. Protocol-based auto VoIP prioritizes the voice data based on
the layer 4 port used for the voice session. OUI-based auto VOIP prioritizes the phone traffic
based on the known OUI of the phone.
