deskphone automatically locks up. The deskphone does not log out and continues to log
missed calls.
• Shared public desk: When a user, for example, a guest, connects the office laptop to a
deskphone at a public desk, the deskphone automatically registers and the phone is unlocked.
When a user disconnects the laptop, the deskphone automatically unregisters or locks. If the
user reconnects to the same deskphone, the deskphone automatically reregisters or unlocks.
• Conference room: This scenario is similar to that at a public desk, but when the user
disconnects the laptop, the deskphone reregisters with the room extension.
• Shared desk with shared computer: This scenario is similar to a desktop computer connected
to an office phone. However in this case, the desktop computer supports multiple user login
accounts as users share the PC and the phone by working on different shifts.
• Contact center: The desktop computer connected to the deskphone runs a contact center
program. When an agent logs in to the computer, the phone automatically registers the user to
a call server. The agent must log in to the call center separately. The agent also has the option
to log in through an agent login Feature Access Code (FAC) to the contact center program.
When the agent logs out of the computer, the phone unregisters, and hence, the agent logs
out of the call center.

Administering a VLAN

This section contains information on how to administer 9600 Series IP deskphones to minimize
registration time and maximize performance in a Virtual LAN (VLAN) environment. If your LAN
environment does not include VLANs, set the system parameter L2Q to 2 (off) to ensure correct
operation.

About VLAN Tagging

IEEE 802.1Q tagging (VLAN) is a useful method of managing VoIP traffic in your LAN. You can
establish a voice VLAN, set L2QVLAN to the VLAN ID of that VLAN, and provide voice traffic with
priority over other traffic. If LLDP was used to set the VLAN for the deskphones, that setting has
absolute authority. Otherwise, you can set VLAN tagging manually, by DHCP, or in the
46xxsettings.txt file.
If VLAN tagging is enabled (L2Q=0 or 1), the9600 Series IP Deskphones set the VLAN ID to
L2QVLAN, and VLAN priority for packets from the deskphone to L2QAUD for audio packets and
L2QSIG for signaling packets. The default value (6) for these parameters is the recommended value
for voice traffic in IEEE 802.1D.
Regardless of the tagging setting, a 9600 Series IP Deskphone will always transmit packets from
the deskphone at absolute priority over packets from the secondary Ethernet interface from an
attached PC. The priority settings are useful only if the downstream equipment is administered to
give the voice VLAN priority.
