Port 80 (specified during the installation of the server) is used by TrueConf Web Manager. *If this port is closed, the Slide Show feature won't be available. Port 4307 (may be changed in TrueConf Web Manager) is used to exchange media data with client applications.

Learn more →

IP A static IP address is required for the server to work properly

1.2. Installation

TrueConf Server is shipped as a software installation package that contains the server side and client applications for popular platforms. After the installation package is downloaded, launch it to begin the installation. The installation process will take less than a minute.

Note: TrueConf Web Manager port is determined during the server installation. By default, port 80 is selected. If it is taken, 8888 is selected. If it is also taken, the user selects the port in the installation dialog window (if the port is not 80, then it is visible in the browser address bar after the colon in the hostname http://localhost:8080).

Your browser will automatically open TrueConf Web Manager (Web interface for configuring the server) after installation.

Note: If you are installing server behind the firewall, then in order to complete the registration you

TrueConf Server Administrator Guide

should open port 4310 access from inside to internet.

How to change port for TrueConf Server Web Manager tool without having to re-install the server

To do this, go to the servers directory (C:\Program Files (x86)\TrueConf Server\httpconf\conf). In the

conf folder open file listen.conf with a text editing app of your choice and change the port number in "Listen (port number)" parameter and save changes. This way you can change the port without re-

installing your TrueConf Server.

1.3. Registration

After the installation of your web browser will automatically start server setup interface. Register the server. To activate the server you have to get a registration key. Click on “Get FREE Key”:

Click to open a page with application to TrueConf Server Free. Carefully fill all the fields and click on “Get a Registration Key”:

A registration key will be sent to the email address that you provided:

TrueConf Server Administrator Guide

Note: The key should be delivered in 15 minutes maximum. If this did not happen, request a key via live chat, or check the SPAM folder in your email client.

Return to the page of TrueConf Server settings and enter the registration key you have just received by e-mail. Press “Register” to continue:

After the server has been successfully registered, on top of the activation window of web-configurator a special sign will appear:

TrueConf Server Administrator Guide

1.4. Offline registration

Note: Offline registration is not available for TrueConf Server Free. In case you need to work with the server in LAN, without connection to the Internet we may provide trial versions of TrueConf Server with full functionality during the trial period.

To register offline on a computer without an Internet connection, you will need a device connected to the Internet to obtain a registration key. On that device, go to https://trueconf.com/server/trial/ and follow the instruction from the "1.3.Registration" section. Once you receive an e-mail with the test key, enter it in the field "Registration Key" in the Web manager on the computer with the running server and without an Internet connection, and click on "Register":

In the registration window a new button will appear, "Create registration file". Clicking on it will generate a file that you will need to send:

TrueConf Server Administrator Guide

Offlinereg.vrg file will be automatically saved in the default "Downloads" folder of the browser. Transfer this file using a flashdrive to a PC connected to the Internet and send at support@trueconf.com. In return, you will get the file you will need to transfer to your PC with the server you are registering offline. * If downloading files option is disabled in your browser, you will not be able to download the offline registration file. Enable downloading option in your browser, then press again "Create registration file".

Note: always wait for a response to a request you have sent and do not restart the offline registration. If you restart the offline registration, the file sent for the previous request would not work aand you will have to do the process again to register.

Click on "Continue offline registration" on your computer and select the file offline.reg:

When offline registration is successfully finished, the Web manager will notify that the server is registered.

1.5. Administering the Server

Server can be administered from any computer in the same local network where it is installed. The access is limited to the following ranges of IP addresses: 10.*, 192.168.*, 172.16-172.31, 127. At this point the installer does not open a port in the firewall for TrueConf Web Manager. If the

TrueConf Server Administrator Guide

administrator wants to administer the server from a remote machine, he/she needs to make sure that the server firewall allows connecting on the port, on which TrueConf Web Manager is launched. TrueConf Web Manager port is determined during the server installation. By default, port 80 is selected. If it is taken, 8888 is selected. If it is also taken, the user selects the port in the installation dialog window (if the port is not 80, then it is visible in the browser address bar after the colon in the hostname http://localhost:8080). To access TrueConf Web Manager from the machine on which the server was installed you will not need any password (the host in the browser - localhost or 127.0.0.1). Remote access requires authorization with the accounts of the Windows users from the group "TrueConf Server Admin". When the server is installed the user account is added to this group. To give another user access to TrueConf Web Manager, the administrator must add the user account to the "TrueConf Server Admin" group. How to Control the TrueConf Server Out of Network -> How to Connect External Users ->

1.6. Log in and Log out from the System

Logging in to the web interface of TrueConf Server is carried out automatically after registration and entering the registration key (see section 3. Registration). To log out from the system (e.g. in order to log in using another key) click the Registration button in the Summary tab:

Enter another key:

TrueConf Server Administrator Guide

If the key is valid you will log out from the system. If you cannot log in to the server when entering the old key on other computer and the message

“Registration key is incorrect. Check that code is valid. If you don't have a key you can get it”

is displayed in the Web Manager tool, this means that your key is “bound” to the hardware on the machine where the server was installed:

If you want to switch off such a bond, please contact our managers: 1-347-878-3263.

1.7. Server status

Server status is shown in the "Server status" field in green (if the server is working) or in red (if it has stopped) in top right corner of the web management tool window:

TrueConf Server Administrator Guide

What to do if server is not running? In this case the red massage “Stopped” will be displayed in the “Server status” line:

Possible reason № 1: You have no license, or the license is expired. Workaround: contact your reseller or distributor. Possible reason № 2: Some server files are missing or have been damaged. Workaround: reinstall TrueConf Server.

Note: You can find information on how to connect client application to server in the "Client Application Connection" section of this document

2.2. Recommended configuration for TrueConf Server client terminal

Intel or AMD Processor with 2 GHz or higher clock speed; 512 MB of RAM and 100 MB free hard disc space; Windows Vista/7 SP1/8/8.1/10 operating system; 256 kbps network connection in both directions; Webcam; Full-duplex sound card; Headset (in order to avoid echo).

2.3. Where can I find client applications

For the users to start video conferencing, the link to the guest page must be distributed among them. On this page they can download client application for all operating systems. Guest page is available at: http://localhost/guest (link may be different ac-cording to the settings of the server). For example, if the port 8888 was cho-sen during the installation, the guest page will be available at http://localhost:8888/guest). You can find the link to the guest page in the Web/Settings Tab on the server settings page.

TrueConf Server Administrator Guide

On the guest page the user can download client applications for Windows, OS X, Linux, Android, and iOS:

2.4. Client Application Connection

You can connect the client application to your server either manually or automatically.

2.5. Connection using auto discovering

The client software of TrueConf includes a function of automatic search for the local server TrueConf Server (auto-discover). It is possible to install the client application without any information about your local TrueConf Server. In this case all information about the server will be detected automatically by using DNS. To do this you need to specify the address of the server in users primary DNS (primary DNS suffix). You need to create SRV record in the domain for vcs2.tcp service and specify the TrueConf Server address and port. The following example shows how to do this using DNS utility in Microsoft Windows 2012 Server:

Navigate to root of the desired domain Choose «Other New Records…» in a right-click menu. Choose type «Service Location». Set the following parameters

TrueConf Server Administrator Guide

In this example server has address videoserver.your.domain.com and port 4307. Please note that protocol name (tcp) does not contain underscores.

2.6. Manual configuration

Open TrueConf Web Manager home page on client computer. Download client application for your system. Share links for downloading client applications for desired platforms. Launch the file on the user's computer and follow system's instructions.

TrueConf Server Administrator Guide

3. Configuring Server

3.1. "Dashboard" Group of Settings

3.1.1. "Summary" Section

This page contains details on the license, registered contact person and available extensions used by the server. You can re-register your server here or proceed to purchasing new licenses for your server. In case of troubles with the registration of the server administrator may contact TrueConf technical support using the contact information that is displayed in case of an error.

If the server is connected to the Internet, administrator will get notifications about server updates. Notification sign will appear in the left menu in TrueConf Web Manager by the "Summary" section. On top of the page a message will be displayed with the link to download new version. After an update the sign and the notification will disappear. If connection to the registration server is lost, your sever will be shut down in 12 hours. The scheduled time of shutdown will be displayed in the tab "Summary".

3.1.2. "Settings" Section

TrueConf Server Administrator Guide

1. Server working directory for saving log files.

2. Enable detailed logging.

3. Server usage statistics.

4. Server usage report.

5. Create server settings backup copy.

6. Restore configuration from en existing Settings file.

12. Display statuses during the conference.

13. Save application settings.

Configuration

A backup copy of the TrueConf Server settings allows you to save the basic settings of your server: users, groups, scheduled conferences, network settings. This capability is useful when re-configuring the server, e.g. when you have reinstalled your operating system. Backup copy does not save files from the working directory as well as recordings. When restoring settings from a backup created on the earlier version of the server, you need to relaunch the installation of the current server version upon completion of restoring. It is necessary for applying the settings to the new version of the server. If server does not run after restoring backup settings, check the network settings: the current IP addresses of the server might not match with the previous IP addresses of TrueConf Server, and you will need to configure the IP addresses again. If you are restoring the settings on an OS other than the OS you ran when you were making backup of those settings, you will need to re-register the server to start it. If you are installing a new version of the server over the old one, all settings are retained, you don't have to apply backup settings after the installation of a new version of the server. If you are installing the older version over the new one or restoring the settings created on a newer version of the server, the stable operation of the server is not guaranteed.

TrueConf Client/TrueConf macOS Settings

By clicking the name of the application (TrueConf Client Client или TrueConf macOS) , you will open the settings tab:

TrueConf Server Administrator Guide

If the current version of the client application is earlier than the said version, the work of the client application will be stopped and it will be updated in a mandatory manner. If the application version is less than the indicated version, the user will be asked to upgrade his client application and given the link to the appro-priate version.

3.2. "Network"

3.2.1. "Network settings" Section

Internal addresses and ports that will be used for clients to contact this server. By default the server

uses all IP addresses of machine on default TrueConf Server port 4307. When default settings are on, current connections are displayed in this column.

External addresses are the ports and IP addresses or DNS names, which help client applications to connect to the server. If the server uses NAT or has DNS names, external addresses can differ from the internal ones.

DNS names can be used for host identification. When using addresses and/or ports translation (NAT), translated address and port must be en-tered into the relevant fields.

If you plan to transfer server to another IP address, you need to enter the future IP address and relevant port into the right column. This will help users to store the future IP address during the next session. When the server is switched to the new address, users will switch to it automatically.

TrueConf Server Administrator Guide

1. To specify non-default external addresses, check "Specify" checkbox

2. To change internal addresses, uncheck "Listen on all IP addresses" checkbox

3. To add a new internal or external IP address. Use the button "Add" and enter the necessary

data in the "Host" and "Port" fields

4. Teturn to previous settings

5. To save the changes

3.2.2. "SMTP" Section

Mail server is used to send notifications to the users about missed calls and to the TrueConf system administrators about the server operation:

1. IP address or SMTP server host name, used by TrueConf Server for sending e-mails

TrueConf Server Administrator Guide

2. Sending e-mail notification to the administrator in case of server reload caused by internal problems

3. Enter the email address which will be used to automatically send emails to the users.

4. Successfully connected status in case of connection to SMTP server, invalid server if the

connection can not be established (use another outgoing e-mail server in this case).

5. Checking SMTP server connection status

6. Option for sending e-mails: without authorization, with a password, with NTLM authorization

(without entering the password)

7. Sending e-mail notifications to the users with missed calls

8. Restoring Default e-mail templates

9. Editable example of subject and body of the letter about the missed call to unregistered users

10. Editable example of subject and body of the letter about the missed call to registered users

11. Activation of an automatic user notification with the upcoming participation in a video

conference

12. Ready-to-edit e-mail template with an invitation to the Group conference

Note: When "simple password" authentication type is selected, new fields will appear in section "Outgoing Mail Server" - "Username" and "Password". Specify your email login and password. If SMTP is configured in the local network, you don't need to fill in these fields. You also need to specify the email details in the fields "Host" and "Port". E.g., if you are using a gmail account, you have to enter "smtp.gmail.com" in the field "Host" and the port value in the "Port" field. If the external mail server demands using SSL (a secure authorization protocol) when authorizing, check the box "Use ssl".

Note: IP address 127.0.0.1 means that you are using SMTP server on the same computer as TrueConf Server. In this case you will be prompted to verify SMTP server installation on this computer.

In case of a missed call to a registered or unregistered user of TrueConf Server this event will be logged on the server and user will be notified by predefined e-mail.

Note: Server logs time of the call, name of the caller, username. This information is substituted by the server in the template using tags:

%recipient_display_name – name; %caller_display_name - display name of the caller; %caller_call_id - id of the calle; %missed_call_time - time of the call.

3.2.3. "SIP Gateway" Section

Components of this tab allow to configure parameters of the SIP gateway. * The maximum number of SIP connections in the free version of TrueConf Server Free is 1. VoIP Server is used for making calls to phones (#tel:89261112233); SIP Proxy by default is used for making calls to Сall_ID of a user (#sip:james78).

TrueConf Server Administrator Guide

1. IP-address or host name of the server, which is used for calls in the PSTN.

2. Account of the VoIP Server/SIP Proxy for the gateway.

3. Password to the account of the VoIP server/SIP Proxy, which is used for the gateway in the

system.

4. The name used to authorize at SIP server. Enter the name if it is different from user ID.

5. Registration mode on a third-party SIP server using REGISTER request.

6. Instead of plus "+" symbol enter in the field the international prefix (e.g. prefix for calls from

Russia: 8-10). Thus, when dialing +7(926)123-45-67, it will be automatically substituted with 8-107(926)123-45-67. If you place the mouse cursor over the field, a popup tip will appear.

7. Display of the status of the connection to the SIP server. Possible values: connected connection with the SIP/VoIP server has been established; wrong authorization - authrization error (wrong login or password); invalid server - incorrectly specified SIP/VoiP server.

8. Save changes.

9. By default, all IP addresses are used. You can un-check the field and add the addresses

manually. To do this, fill the Host and Port fields. Then click on "Add". The table on the left will display the submitted information. They can also be deleted. To do this, select the one you want to delete by checking the tick on the left and click on "Remove Selected".

10. Domain name or IP address of the server. Click on "Apply" so that the incoming calls are displayed as user@domain, where domain is the Outgoing SIP domain. This allows SIP users to call back the users of the server.

3.2.3.3. Invitation of the SIP terminal to the conference that is held on the TrueConf Server.

There are two ways ot inviting a SIP endpoint into a video conference - from Address book of TrueConf Client application or from TrueConf Web Manager.

1. From Address Book in TrueConf Client application. Do the following:

TrueConf Server Administrator Guide

add SIP endpoint to the Address book in the following format: #sip:user@host, where "host" is IP address or a domain name; call it by a double-click on the name of the subscriber:

2. From TrueConf Web Manager. to do this: create and plan a group video conference, using the tab "Group conferences"; enter SIP endpoint as a participant of the conference. In the indicated day all the participamts will be invited to the conference:

3.2.3.4. Connection using CID (Conference ID)

If several group conferences are organized on TrueConf Server, you can choose the conference directly from the SIP terminal. For that:

Organize a group conference in the Group Conferences tab of TrueConf Server configuration wizard; Remember the CID (e.g. \c\e22a39ba2a); In the address bar of the terminal make call on your CID@IP, where IP – address of the TrueConf gateway. Note: some terminals (for instance, Polycom PVX) de-lete special symbols from the address bar. In this case for Polycom PVX you will need to enter \\c\\e22a39ba2a@IP.

3.2.3.5. Connection to the fixed name group conference

Organize a group conference in the Group Conferences tab of TrueConf Server configuration wizard; Remember the CID (e.g. \c\e22a39ba2a); In the Application tab of TrueConf Server configuration wizard create property default_mconf_name, equal to the CID without \c\, for the given example: e22a39ba2a; Restart TrueConf Server; Make a call to the name groupconf@IP from the terminal, where IP is address of the TrueConf Gateway.

3.2.3.8. Troubleshooting

SIP-terminals do not connect with TrueConf Server

Description Possible reason Solution of the problem

SIP terminals cannot connect with TrueConf Server.

Invalid IP address in the TrueConf Server configurations.

Check rightness and correspondence of the data in the SIP Gateway tab of the configuration wizard:

Address: an IP address of the network interface used for TrueConf gateway; Server: IP of the host interface, which is used for VoIP/SIP server.

TrueConf Server is offline or has intermediate status.

Run TrueConf Server by clicking System/Start.

Absent or incorrect parameters of TrueConf Sever on the SIP terminal.

Indicate valid IP address and TrueConf Server port in the parameter window of the SIP-terminal.

Invalid input format for conference parameters.

Please refer to SIP endpoint user’s guide to check input format for conference parameters.

TrueConf Server Administrator Guide

No network connection.

Check network connection on the PC with SIP terminal (if SIP terminal is installed on the PC). To do this you can use "ping" command with IP address of the PC where TrueConf Server is installed.

There is no video and audio in the conference between TrueConf Server and SIP terminal.

Incorrect codecs negotiation.

Make sure that SIP terminal supports one of audio codecs: G.711 (alaw/ ulaw), G.728; and video codecs: H.264, H.263.

Description Possible reason Solution of the problem

3.2.4. "H.323 Gateway" Section

Settings on this page are designed to register the TrueConf Server on the external H.323 gatekeeper. After registered successfully, TrueConf users are able make calls to terminals registered on this gatekeeper with the following dialing format: #h323:terminal_id, where “terminal_id” is the terminal identifier you are calling to.

Note: #h323:terminal_id is identical to #h323:h323-id (e.g. #h323:ivan), or #h323:\e\e164 (e.g. #h323:\e\202).

1. Enter the address of the H.323 gatekeeper. You can use either a domain name (e.g. test.gatekeeper.com) or IP address (e.g. 34.87.12.127).

2. Enter H323-ID (random alphanumeric identifier) under which the TrueConf Server will be registered on the external gatekeeper. For instance, H.323-ID might be this way: #h323:user01. H.323 terminals can call this number to reach TrueConf Server using gatekeeper.

3. You need to enter DialedDigits (E.164), under which TrueConf Server will be registered on the external gatekeeper.

TrueConf Server Administrator Guide

4. Enter the password received from the administrator to register the TrueConf Server on gatekeeper. If you leave this field empty, the registration without a password will be used.

5. The switch can be used to temporarily disable the server registration on the gatekeeper.

6. After making changes to "H.323 Gatekeeper" section, click “Save” to commit the changes. It is

necessarily to restart is the server.

7. This section contains TrueConf Server settings necessary for work in the Gatekeeper mode. In this mode third-party H.323 endpoints can be registered on the server under the user account of TrueConf Client application.

8. as explained above, after registered the TrueConf Server on the external gatekeeper, you can make calls to the server using its registration data (h323-id and/or Dialed Digits (E.164)). This section is used to determine the recipient of these numbers. Enter the TrueConf ID or Conference ID (CID) of the recipient in the input field and press “Apply”. If left empty, calls to the client application of the TrueConf Server will be rejected.

DialedDigits

DialedDigits (E.164) is an identifier consists of numbers and special characters, «,#*» (for instance, dial #h323:\e\041412 to call the subscriber 041412). Please note that the characters \e\ are mandatory when using Dialed Digits (E.164). Thus, if you dial #h323:041412, H323-ID will be used instead of DialedDigits (E.164)and the call can be addressed to other subscriber. After registration, other terminals will be able to make calls to the client application TrueConf using this identifier.

Note: It is not necessary to indicate h323-ID and DialedDigits (E.164) simultaneously. To register a server on the H.323-gatekeeper you only have to enter one of them.

Network settings

In this mode third-party H.323 endpoints can be registered on the server under the user account of TrueConf Client application. Thus, a user may log in to a server using either TrueConf Client or any H.323 endpoint with a support for password-based registration. By default if 'Use all IP addresses' is selected, TrueConf Server will use all accessible connections by default (server's IP addresses + port

1719). Do not change this section without necessity. If you need to change IP addresses or ports to

access TrueConf Server (e.g. to deny access from a particular IP, or if port 1719 is blocked by Firewall and you need another port) uncheck 'Use all IP addresses'. In this case, three buttons will be activated: Add, Reset, and Apply. Using the Add button you can set an additional access point (you should input an IP address for the access in the drop-down window (in the Host field), port, and protocall (TCP or UDP)). By clicking any access point in the list, a similar editing window will open. If you click the Reset button, all changes will be reverted to the previous saved state.

Default Call Destination

After registered the TrueConf Server on the external gatekeeper, you can make calls to the server using its registration data (h323-id and/or Dialed Digits (E.164)). This section is used to determine the recipient of these numbers. Enter the TrueConf ID or Conference ID (CID) of the recipient in the input field and press “Apply”. If left empty, calls to the client application of the TrueConf Server will be rejected.

3.2.4.1. How Can a TrueConf User Make a Call to an H.323 Endpoint?

The administrator of a server must register an H.323 endpoint first. For information about how to do this, see a detailed instruction. Enter the H.323 endpoint data in the Address Book. The ID of an H.323 endpoint should look like this:#h323:@IP, where IP is its address:

Federation between servers

Federation allows subscribers of different TrueConf Server to make video calls, conduct group conferences and use collaboration tools. The server which has a "Federation" option enabled provides media streaming between remote servers that support this feature it too. The number of servers involved in Federation is unlimited. Group video conferences will be conducted with regard to the limitations specified in the license of the server, initiating the connection. Video calls and group conferences during Federation are held on the same principle as within one TrueConf Server. No additional server adjustments should be done when using Federation feature. Still, the following conditions are to be observed: you need to have license for TrueConf Server with

TrueConf Server Administrator Guide

Federation feature for all servers that participate in Federation, possibility for all servers and subscribers to connect to your server during Federation. The server should be available to other servers by its name, indicated at registration. The server can be registered on the existing DNS name, as well as be specified by the actual server address with the help of the SRV records DNS. To read more please see section "Connection using auto discovering".

Note: In case your server does not support Federation, following the Federation tab notification will be displayed: Federation mode is not available for yourserver license. To Activate this feature, contact our managers.

3.3.3. "HTTPS" Section

In this section of the Web Manager Tool you can configure a safe data transfer channel between browser and web server via HTTPS protocol and also between browser and TrueConf Server via WSS protocol.

TrueConf Server Administrator Guide

1. This section contains the following settings: choosing one of HTTPS modes; choosing a port which will be used for connection via HTTPS protocol; testing the chosen settings; choosing a port which will be used for connection via HTTPS protocol; applying the chosen settings.

2. Choose one of three modes: turn of HTTPS - this mode turns off the HTTPS protocol; use self-

signed certificate - this mode uses the certificate obtained from the Web Manager Tool; use downloaded certificate - this mode uses a certificate uploaded by the administrator of TrueConf Server.

3. Tutorial "How to Configure HTTPS in TrueConf Server"

4. Set TCP port, which responds to the web server for operation via HTTPS protocol. Port value is

443 by default. Only digits are available for entering to this field.

5. Click this button to verify HTTPS configuration data without restarting the web server. This

action does not change the configuration file of the Apache web server. Verification is perfomed by the steps specified in the Verification and adoption of settings block.

6. Generate a new sertificate. The Self-Signed Certificate section has such an appearance only if

this certificate type has not been issued before. Should certificate has been already issued, this section would contain the main data of root certificate and certificate which will be used by the web server and TCS (refer to the Self-Signed Certificate block description).

7. To download certificate files and key you should choose them and click the Download button.

The Downloaded certificate section has such an appearance only if this certificate type has not been issued before. Should certificate has been already downloaded, this section would contain the main certificate data (refer to the Downloaded Certificate block description).

The existence of safe connection channel between browser and server is essential for media devices capture by means of browser using WebRTC technology for Google Chrome browser starting from version 47. To set a safe connection, the server administrator needs certificate file in X.509 format and corresponding private key file.

There are two types of certificates available for use in the Web Manager tool:

Self-Signed; Fully-Featured.

Self-Signed Certificate

TrueConf Server Administrator Guide

Capabilities:

Generated by the Web Manager tool, issues for 365 days. Can be extended for an unlimited period. Can run WebRTC testing without a fully-featured certificate.

Details:

Manual installation of root certificate is required for all client devices where HTTPS and WSS will be used. The process of root certificate installation is different for Chrome and Firefox.

Fully-Featured Certificate

This type of certificate should be bought in the Certification Centre (CC). Fully-featured certificate doesn’t require any additional operations with client devices, since browser trusts the publisher who signed it.

Settings Revision and Adoption

Web server uses HTTPS settings at launch. Wrong port and certificate data can cause server error and administrator will lose access to the Web Manager tool. Therefore, it is highly important to make thorough check of the preset parameters. The best way to check the parameters is to launch a web server copy using specified HTTPS settings with further analysis of launch results (currently the installation wizard works in this way when choosing a web server port). In the Web Manager tool project PHP operates as an Apache module, which doesn’t allow launching a web server copy from PHP script as it’s not possible to launch a new control process from an already existing one. Therefore, at this stage it is necessary to check the entered data according the following steps:

Check availability of a specified HTTPS port for using it with Apache server. Check the file specified as certificate for compliance with X.509 format by means of openssl library. Check the file specified as private key by means of openssl library. Check the private key and certificate compliance by means of openssl library.

Self-Signed Certificate

If the certificate has already been issued, this section will contain basic parameters of root certificate and certificate which will be used by the web server and TCS:

Administrator can download a root certificate file for sharing among client devices via the link Download ca.crt.

TrueConf Server Administrator Guide

The Create new SSL certificate button allows to reissue a server certificate signed by the same root certificate if expiration date is still valid. Otherwise, the certificate will be signed by a new root certificate. This option is necessary to extend the validity period for another 365 days or to update your company information in the certificate.

Downloaded Certificate

If the certificate has already been downloaded, this section will contain basic parameters of the certificate. Certificate format, key format and key correspondence to certificate are being checked during download. Should at least one check fail, certificate and key files would not be not saved.

accompanying text to reports of participants or event schedule). The text will be displayed on the Home Page when external users are connected.

11. Press to setup streaming (see Streaming)

Server response time

If the server-receiver did not send the conference data acquisition notification the broadcast is interrupted. Such a verification is necessary because RTSP broadcasting process is one-sided (broadcast data is sent only from TrueConf Server side to the server-receiver side). The verification is carried out by the protocol, which does not provide information to the sender (TrueConf Server) that the recipient (serverreceiver) has received the broadcast data. As a result, a server-receiver must send the data acquisition report within the stated time independently.

Another advantage the option provides: in case the server-receiver shuts down and will not notify the TrueConf Server, TrueConf Server finds it out and stops spending resources on sending data where unnecessary.

Possible field values: 0 - data delivery verification is off. It is useful to turn off the verification when the server-receiver can not send the data acquisition report, proceeding with the data acquisition. In this case the broadcast can be interrupted by the verification at the most unsuitable moment. It is required to specify the verification process in advance while working with such kind of unstable servers. 0 > (greater than 0, e.g. - 60 seconds, time set by default) - verification is on within the stated time period. After this period of time in case of no conference data report returned from the server-receiver the broadcast is interrupted.

Conference mode Section

This section includes experimental features designed to extend your server functionality by integrating the server with third-party services and products. We do not describe existing add-ons, because interfaces of third-party services are often changing without notice. In such conditions we could not guarantee the accuracy of this guide.

Nevertheless, we have tried to make the interface for add-ons accurate and user-friendly. We also wrote great instructions on how to use these add-ons in our blog.
