...

tar -xvzf FlashphonerWebCallServer-5.2.XXXX.tar.gz
cd FlashphonerWebCallServer-5.2.XXXX
sudo ./install.sh

The installer will perform necessary checks and installs WCS to the following directory /usr/local/FlashphonerWebCallServer

...

• bin - WCS executables
• client - WCS JavaScript API 1.0, usage examples and stress-tests
• client2 - WCS JavaScript API 2.0 and usage examples
• conf - configuration files
• lib - required libraries
• tools - tools to debug WCS
• web - WCS web interface static pages

Silent mode installation

Sometimes, WCS can be installed in silent mode if automatic deployment system like Ansible is used to deploy a number of typical instances

./install.sh -silent

In this case:

• IP addresses detection does not work (flashphoner.properties file and other settings are supposed to be overwritten by automatic deployment system)
• webcallserver.service is configured to start from root

Installation to a different Java versions

JDK 12 or 14

The following settings should be removed from wcs-core.properties file

-XX:+UseConcMarkSweepGC
-XX:+PrintGCDateStamps
-XX:+PrintGCDetails

The following setting

-Xloggc:/usr/local/FlashphonerWebCallServer/logs/gc-core-

should be replaced by

-Xlog:gc*:/usr/local/FlashphonerWebCallServer/logs/gc-core-:time

JDK 15

In addition to setting changes made for JDK 12 or 14, the following settings should be removed from wcs-core.properties file

-XX:+UseCMSInitiatingOccupancyOnly
-XX:CMSInitiatingOccupancyFraction=70

JDK 16

In addition to setting changes made for JDK 12, 14, 15, the following settings should be added to wcs-core.properties file

--illegal-access=permit

JDK 17

In addition to setting changes made for JDK 12, 14, 15, 16, the following settings should be removed from wcs-core.properties file

--illegal-access=permit

and the following settings should be added

--add-exports java.base/sun.security.provider=ALL-UNNAMED
--add-opens java.base/java.lang=ALL-UNNAMED

Acquiring a license and activation

...

On first logon to WCS web interface by address httphttps://yourserver:8444/admin/, where yourserver is your server hostname with by default user admin (password admin), the request for license number is displayed:

...

cd /usr/local/FlashphonerWebCallServer/bin
sudo ./activation.sh

The script asks you to enter the license number:

...

sudo ./deactivation.sh

If activation fails

...

For example, a test server on Amazon EC2 has the external IP address of: 54.189.212.111, and the network interface address is: 172.30.21.25. If your server is behind NAT шт in regard to browser clients, write down or copy these IP addresses. You will need them later, when you will configure the server.

Automatic and semi-automatic IP addresses detection

Since build 5.2.921, WCS tries to automatically detect server IP addressess on startup if they are not set, or server is starting in cloud environment supporting AWS API or Google Cloud API endpoints. If IP addresses cannot be detected on startup, it may be done manually using the following command

cd /usr/local/FlashphonerWebCallServer/bin
sudo ./webcallserver set-ip

This command:

• tries to detect IP addresses automatically;
• if this cannot be done, asks user for additional data
• writes results to flashphoner.properties file

It is recommended to use this command if there are some problems with IP addresses detection behind NAT.
