Unified Communication Use Cases

Installation

Requirements

Trying it out

Here are the system minimum requirements if you just want to try out a Wazo Platform instance:

CPU: 1 CPU is enough for a test server
Memory: 2 GiB of memory is a tight minimum for a test server
Storage: 8 GiB is comfortable for a test server, except if you plan to use large firmware files for physical phones.

Production

Here are the expected resources for a small production installation of around 50 users:

2 CPU minimum
4 GiB RAM minimum
50 GiB storage minimum

Procedure

To install the Unified Communication use case in an all-in-one setup, do the following steps:

Install a Debian 11 Bullseye system with a default locale with an UTF-8 charset.
Run the following commands as root on the Debian system to provision sudo, git and Ansible:
```
apt update
apt install -yq sudo git ansible curl
```
Note: Ansible is a suite of software tools that enables infrastructure as code. It is open-source and the suite includes software provisioning, configuration management, and application deployment functionality. https://en.wikipedia.org/wiki/Ansible_(software)

Extract the Wazo Platform installer

git clone https://github.com/wazo-platform/wazo-ansible.git
cd wazo-ansible

(optional) By default, Wazo Platform will install the development version. To install the latest stable version
```
ansible_tag=wazo-$(curl https://mirror.wazo.community/version/stable)
git checkout $ansible_tag
```

Install the Wazo Platform installer dependency

ansible-galaxy install -r requirements-postgresql.yml

Edit the file inventories/uc-engine to add your preferences and passwords. The various variables that can be customized are described here.

By default, Wazo Platform will install the development version. To install the latest stable version, activate the following settings in inventories/uc-engine:
```
[uc_engine:vars]
wazo_distribution = pelican-bullseye
wazo_distribution_upgrade = pelican-bullseye
```
If you want to install the web user interface, activate the following in your inventories/uc-engine:
```
[uc_ui:children]
uc_engine_host
```
The following variables allow you to create the root account at installation time, to be able to use the web user interface and an API user to be able to use the REST APIs:
```
[uc_engine:vars]
engine_api_configure_wizard = true
engine_api_root_password = <YOUR_ROOT_PASSWORD>
api_client_name = <YOUR_API_USERNAME>
api_client_password = <YOUR_API_PASSWORD>
```
Note: this API user will only have permissions for configuration REST API (wazo-confd).

Launch the installation by running the following command:

ansible-playbook -i inventories/uc-engine uc-engine.yml

Once the installation completed, execute the following command to verify that all the Wazo services (wazo-plugind, wazo-webhookd, ...) are up and running:
```
wazo-service status
```

Use the REST API

You may now use the REST API from outside your system (here wazo.example.com).

Get an authentication token for 1 hour:

Execute from the Debian system:

wazo-auth-cli token create --auth-user <YOUR_API_USERNAME> --auth-password <YOUR_API_PASSWORD>

Or with curl from anywhere:

curl -k -X POST -u <YOUR_API_USERNAME>:<YOUR_API_PASSWORD> -H 'Content-Type: application/json' -d '{"expiration": 3600}' https://wazo.example.com/api/auth/0.1/token

Use any REST API you want.

Note: You must replace <YOUR_TOKEN> with the authentication token

To obtain the version of Wazo:

curl -k -X GET -H 'X-Auth-Token: <YOUR_TOKEN>' -H 'Content-Type: application/json'  https://wazo.example.com/api/confd/1.1/infos

To list the telephony users configured on the system:

curl -k -X GET -H 'X-Auth-Token: <YOUR_TOKEN>' -H 'Content-Type: application/json' https://wazo.example.com/api/confd/1.1/users

Optional post-install steps

You may now follow the optional post-install steps.
