1.14.3 Power Boost
Power Boost enables the desk phone to provide more USB power (to power an expansion module,
for example).
Power Boost is enabled:
• When the desk phone is powered via 5V 3A USB-C PD power adapter.
• When the Power Boost is activated by the administrator on the system side, the desk phone
will dynamically adjust its PoE class (Class 3) to provide more power on USB ports. In this
case, the phone will restart and change its USB current limiter management in order to
increase the available power.
Contact your administrator if necessary.
1.14.4 USB hub
If both USB-c ports are used (e.g. for power supply and headset), your desk phone supports most
commercially available dual port USB-c hubs. For more information, contact your installer or
administrator.
1.15 Audio encryption
Your desk phone supports telephony encryption. On a secured telephone network (IPTouch
Security, SSM box), voice and signaling are encrypted.
If the communication is encrypted, the following icon is displayed in the
communication screen. The call in progress icon is replaced by this icon.
In idle state, the following icon is displayed in the status bar to indicate that the signal
is encrypted (depending on the icon priority, see chapter:Status icons).
Your phone supports many audio and signal encryption types. The native encryption mode is defined
in the local administrator menu of the phone (Native Encrypt). For more information, contact your
installer or administrator.
