Hot Desking
Employees in enterprises that operate according to a 'touch-down desk' concept can use the
phone's HostDesk feature. Employees in these enterprises typically travel frequently to remote
branches, or work in shifts. They can sign in to a phone that is already signed in by another (CAP
or regular) user without signing out the original user to whom the phone was assigned for primary
use.
 To use the HotDesk feature:

Press the MENU key on the phone.
2.
Click the HotDesk softkey displayed; the 'HotDesk Sign-in options' screen opens – identical

Select PIN code -or- Username and Password -or- Web Sign-in (see under Section 3.5 for
more information).
Note:
• If the feature isn't enabled on the server, the enterprise's network administrator must
enable it for the feature to be available.
• When the HotDesk user signs out or if the phone stays in idle state longer than the
HotDesk timeout defined on the server, the phone automatically returns to its original user
and state; its configuration and data are preserved as they were before the phone was
leased for HostDesk use. HotDesk users cannot perform all operations that the original
(CAP or regular) user could perform, for example, change Language.

is displayed on phone screens when the paging call comes in.
Note:
• For detailed information on configuring a Functional Key for paging on the phone, see
Section 5.19.
• The feature must be enabled in the Web interface by the network administrator before a

Setting up Better Together over Ethernet
This section shows how to set up the Microsoft Skype for Business feature 'Better Together over
Ethernet' on AudioCodes' 400HD Series of IP Phones.
BToE enables operations to be mirrored on both AudioCodes' IP phone and the Skype for
Business client on the PC/laptop, so that these operations can be controlled from either the
phone or the PC/laptop, whichever is convenient to the user at the time, for enhanced unified
communications and optimized enterprise efficiency.
After your phone is paired with your Skype for Business client, you can control (from phone or
PC/laptop) operations such as answering incoming calls, making outgoing calls (click-to-dial),
putting calls on hold and resuming them, and making conference calls.
7.11.1 Installing the BToE PC/Laptop Application
This section shows how to install AudioCodes' BToE PC/laptop application.
 To install the BToE PC/laptop application:
1.
After obtaining the installation file whose name will be either AudioCodes BToE.exe or
AudioCodes BToE.msi, save it to your PC/laptop and then double-click it.
Note:
• The msi file is for the purpose of network administrator distribution. Users are not allowed
to install BToE using the msi file, only using the exe file.
• After installing with the exe, then when upgrading the exe must be used. Upgrading with
the msi cannot be done if the first installation was with the exe, and vice versa.
• Some PCs require the installation of .Net 4.0 prior to the installation of the BToE
PC/laptop application. If you use the installation file AudioCodes BToE.exe, the
Installation Wizard will detect that .Net 4.0 is missing and will prompt you to install it:
When installing the BToE PC/laptop application using the installation file AudioCodes
BToE.msi, you won’t be prompted to install .Net 4.0 and the network administrator should
make the necessary preparations prior to installation of the BToE PC application.

7.11.3 Configuring the BToE TCP Port
You can opt to configure a different BToE TCP port to the default 9999, depending on the
requirements of your enterprise. For example, you may decide to change the BToE TCP port to
5000 because your enterprise is using the default port of 9999, and 5000 is available. This
feature therefore provides enterprise administrators with more freedom in network administration.
Note: If you decide to change the default BToE TCP port, you must update both the
PC/laptop and the phone with the new BToE TCP port number.
 To change the BToE TCP port on the PC/laptop side:
1.
Click the AC (AudioCodes) taskbar icon; the menu shown in Figure 7-14 pops up.

7.11.5 Automatically Pairing the BToE PC/Laptop Application with the
Phone
Pairing is automatically performed when the phone's PC port is connected to the PC/laptop
'behind' the phone. See the Administrator's Manual for more information.
Note: Automatic pairing requires BToE PC/laptop application Version 2.x.
If the laptop after automatic pairing is disconnected and moved to another location, its
speaker/headset becomes the audio device associated with the Skype for Business client.
If the laptop is manually paired and then relocated, Skype for Business audio will remain through
the phone. It's therefore advisable to pair automatically.
Note: If the BToE PC/laptop application has already been manually paired with the phone, as
shown in the section below, and you want to automatically pair, you must delete the old pair
code from the BToE PC/laptop application in order to allow BToE automatic pairing:

Note:
For this feature to function:
• Your network administrator must enable private voicemail for you.
You must sign in to the phone with your username and password. If you signed in with
your PIN code, voicemail will be unavailable and you'll see the message Your account is
not configured for Exchange Unified Messaging.
• Features like this, activated from Microsoft's Exchange Server, are only available after
signing in to the phone with Username and Password.
• By default, the phone skips PIN code authentication and allows users direct access to
voicemail. The network administrators can secure user access to voicemail with PIN code
authentication so that when the user presses the voicemail key, they're prompted to enter
their PIN code. See the Administrator's Manual for details.
When you have at least one new message in your voicemail box, you can listen to it.
