General information

First, the Link must be installed and configured on a computer to work correctly and provide access in a web browser. It can be done with the help of:

multiple Docker containers and deployed with Docker Compose;
Virtualbox virtual machine image;

Further, you will find detailed installation steps for both methods.

There are several Link server variations, so before the installation choose the one that is required:

Link without SIP and without web proxy;
Link without SIP but with web proxy;
Link with SIP but without web proxy;
Link without SIP but with web proxy;

In the beginning, you get Link basic version, and further you can buy access to the Link License server to expand software functionality. More details about functionality can be provided with licenses you can find in the corresponding tab.

Installing Link under Linux using Docker

Install Docker for your distro. The example below uses the installation for Ubuntu.

# Remove old versions

sudo apt-get remove docker docker-engine docker.io containerd runc

# Configure the repo
## Update apt index and install dependencies

sudo apt-get update

sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

## Add Docker GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

## Add repo

echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null


# Install Docker

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io

Install docker-compose for your distro.

# Download docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# Grant execute permission for the file

sudo chmod +x /usr/local/bin/docker-compose

# Add symlink

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Clone the necessary project from our GitHub with the help of command.
```
git clone https://github.com/basip/link.git
```
Create the necessary volumes in advance, with help of the command:
```
docker volume create name
```
Name changes depending on the volume name to be created. The list of required volumes (with external: true values) you can find at the end of the docker-compose.yml file.

So, according to the example, the following commands must be done:
```
docker volume create app-data
docker volume create app-storage
docker volume create system-logs
docker volume create app-ssl-certs
```
Go to the folder of the version you want to install. For example, for the version without SIP, the command is:
```
cd link/without-sip
```
Run the project.
```
docker-compose up -d
```

Used ports

The application uses the following ports:

5060 TCP/UDP: unencrypted SIP traffic port;
5061 TCP: port for SIP using TLS;
80 TCP: HTTP port;
443 TCP: HTTPS port;
6001 TCP: WebSocket port;
10000-20000 UDP: RTP ports for audio/video;
1883 TCP: unencrypted MQTT;
8883 TCP: encrypted MQTT;

If SIP proxies and nodes are running on more than one server with the Link server application, then the following ports must be forwarded to them:

48080: SIP proxy management port;
48081: SIP node management port;
