Once you have turned on the endpoint for the first time, you need to configure your network
connection parameters and control panel access.
3.1.1. Setting an IP Address
To set an IP address, gateway and subnet mask for the endpoint, go to
Configuration → Network → IPv4.
If your network has a DHCP network service, check the corresponding box to configure the connection
automatically. Otherwise, configure the following parameters manually:
IP address
Mask
Gateway
Primary DNS
Secondary DNS
Interface settings: To fine-tune the network, you can disable Autonegotiate and set up Network
speed and Duplex mode manually (half duplex or full duplex).
If your network uses IPv6, you can configure it in Configuration → Network → IPv6.
If the network connection is successful, TrueConf Group IP address will be displayed at the top of the
screen.
3.1.2. Control Panel Access
To manage conferences remotely (using the web interface), go to
Configuration → Network → HTTP, enable HTTP access, select a port, and set up authorization
data.
Once this is complete, you can access the control panel at the address specified in IP settings. The
same address will be displayed at the top of the screen when working with the endpoint menu.

connected keyboard, while you are in the main menu.
Tip
If you have forgotten the password to access the endpoint settings, you can change or reset it
in the control panel.
3.4. Hardware Setup
Choose your device models from the below sections. If a device is not included in the standard
configuration of TrueConf Group, its name will be displayed with a mark in square brackets in the list,
e.g., [USB] CleverMic.
3.4.1. Monitors
TrueConf Group supports two monitors simultaneously connected using HDMI and DisplayPort. To
configure these monitors, go to Configuration → Video → Output devices section.
If both monitors are connected, choose the monitor to display the main menu of the endpoint in the
drop-down list Main menu on:.
Use Show local video: to choose whether you will see your selfview during a call.
In Secondary display content menu, choose what should be displayed on the additional monitor:

Microphone gain and try to enable Microphone boost.
Warning!
Using the microphone input gain along with the volume can cause noise or sound distortion.
We recommend using this setting only if it is absolutely necessary.
To remove echo, return to Configuration → Audio → Input device section and enable Noise
suppression. If this does not help, use Microphone gain control, AEC, and AEC settings to achieve
the best combination of settings. When using a USB speakerphone, echo and noise cancellation needs
to be disabled, and it should be enabled when using an analog microphone or equivalent connected
via a mini jack. When a speakerphone is used to capture sound, and a device connected via HDMI, e.g.,
TV or monitor speakers, is used for output purposes, a hardware echo canceller can't work, as you
need to use a software one.
Audio settings (noise cancellation, echo cancellation, and volume) are saved for each device
individually.
3.4.4. Speakers
Go to Configuration → Audio → Output device and choose a speaker in Default output.
To test sound playback, click Start in Speaker test. If connection is successful, you should hear a short
piece of music.
Tip
Check your speaker connection in Configuration → Audio → Diagnostics.
3.5. Configuring Protocols
3.5.1. H.323 Settings

2. In necessary, enable NAT traversal for H.460.18 and H.460.19.
3. To register the endpoint with an external H.323 gatekeeper, choose Discover in Gatekeeper use:
to find its address in the network or Manual to enter the address manually and indicate:
H.323 extension (E.164) and H.323 Alias in case of calls from devices within the gatekeeper
without the need to indicate the endpoint IP address (otherwise the system name will be used as
the default value)
Gatekeeper address (in case of manual input)
Gatekeeper username and Gatekeeper password for authorization (if necessary)
3.5.2. SIP Settings
To enable your endpoint to use the SIP protocol, configure it in Configuration → Network → SIP
section.
1. Enable SIP support.
2. If necessary, enable Spam protection. This feature is useful when the endpoint becomes available
via SIP from outside the local network. In this case, it can be attacked by different types of malware
that looks for poorly protected corporate IP PBX systems to forward traffic. These attacks are spam
calls to the endpoint. When antispam protection is enabled, TrueConf Group software identifies
such calls by their characteristic features and ignores them.

equipment.
You can change settings in Configuration → Powersave section:
1. Choose the length of time before the endpoint goes into sleep mode.
2. Indicate if this should:
Turn off monitors and cameras
Put the camera into sleep mode (if supported by the manufacturer)
3.7. Preparing for Conferences
3.7.1. MCU Function Activation
By default, TrueConf Group operates in point-to-point mode when the video call is made in full-
duplex mode that allows two parties to see and hear each other simultaneously. If another user calls
the endpoint during the ongoing session, he/she will not be able to join and will see a message that
the device is busy.
At the customer's request, the endpoint can be equipped with an embedded MCU server. When
TrueConf Group operates in this mode, the video call is put into group conference mode. In this case,
users who are calling the endpoint automatically join an ongoing conference (according to the number
of external connections allowed by the license).
Take the following steps to enable this feature:
1. Go to Configuration → Call → MCU settings section.
2. In MCU support, choose On.
3. Indicate Mixing mode for video streams:
Symmetric: All conference attendees see and hear each other
Video lecture: Attendees who joined the conference see and hear only the host represented by
the endpoint
Voice activated: All attendees have a layout as in a symmetric conference, but a speaker will be
displayed in the priority video window.
4. If necessary, enable the display of the volume indicator in each video window.
5. If you do not want a layout to automatically create a new video window for a presentation or
