802.1 p priority bits in the 802.1Q header can be set. 802.1Q headers
must be enabled by the Network Interface Card (NIC) or NIC driver. The
i2050QosSvc does not fill in other fields in the 802.1Q header (for example,
no values are assigned to the VLAN ID field).
The default VLAN ID value in Windows is 0. This can be overwritten for Network
Interface Cards (NIC) that support 802,1Q. The 2050 processes do not assign
values to the VLAN ID field. This setting is documented with the NIC or the
NIC driver.
The VLAN ID for an application must match the VLAN ID for the PC because the
PC has only one IP stack for each NIC. A second IP stack is required to assign a
specific VLAN ID tag for an application which is different than the PC tag.
You can use two different IP cards, each with different VLAN ID values on a single
PC; however, this can cause security gaps on the voice VLAN, which is normally
a more secure network than the data VLAN.

DiffSERV (DSCP)

The IP Softphone 2050 uses DSCP settings assigned by the TPS. The
IP Softphone 2050 supports DSCP on Windows 2000 Professional and
Windows XP. For information about configuring DiffServ values, see IP Line
Fundamentals (NN43100-500).
802.1p
For information about configuring 802.1p values, see IP Line Fundamentals
(NN43100-500).

Ethereal traces

Current versions of Ethereal show 802.1Q headers, if they are present.
802.1Q must be enabled on the NIC for the headers, which includes 802.1p
to be captured.

Licenses

The IP Softphone 2050 Release 3.0 requires a license to operate. If the
phone cannot obtain a license from one of the licensing schemes then
it cannot connect to a Call Server and an error message appears on the
phone screen.
While the IP Softphone 2050 runs, it first goes through three licensing
schemes before it connects to Call Server. After the phone obtains a license,
it repeats the procedure at a random interval. If the licensing scheme fails
then the IP Softphone 2050 disconnects from the Call Server unless you
are on an active call, in which case the phone does not disconnect until
the call ends.
