Instalar y Configurar ISSABEL PBX (ASTERISK) Desde Cero

How to Install and Configure Isabel with Asterisk

Introduction to VoIP and Installation Overview

• The video begins by introducing the concept of VoIP (Voice over Internet Protocol), explaining how applications like WhatsApp utilize an IP telephone central for making calls.

• It highlights that IP telephony is widely used in businesses today, setting the stage for a tutorial on installing and configuring Isabel with Asterisk.

Downloading and Setting Up Isabel

• Viewers are directed to the official Isabel project website (isabel.org) to download the ISO file necessary for installation.

• The presenter mentions that the ISO file size is 1.5 GB, indicating they will skip downloading since it’s already available on their system.

VirtualBox Configuration

• Instructions are provided on how to set up a new virtual machine in VirtualBox, naming it "Isabel" for identification purposes.

• The process includes uploading the previously downloaded ISO image into VirtualBox, ensuring it's configured correctly as a Gentoo operating system.

System Resource Allocation

• The presenter discusses memory allocation, suggesting default settings while allowing viewers to customize RAM and CPU cores based on their needs.

• Emphasis is placed on configuring network settings by changing from NAT to Bridged Adapter for proper connectivity.

Installation Process Begins

• Once the virtual machine starts, viewers are guided through selecting installation options using keyboard navigation.

• Language selection is crucial; Spanish is chosen here, followed by country configuration which activates installation buttons.

Keyboard Configuration and Software Selection

• Testing keyboard functionality ensures all special characters work correctly before finalizing configurations.

• Viewers learn about software selection during installation; choosing Asterisk version 11 enables call center features not present in later versions.

Finalizing Installation Settings

• Disk space allocation is confirmed before proceeding with the installation process; an 8 GB hard drive setup is noted as sufficient for basic use.

Installation and Configuration of a PBX System

Initial Setup

• The installation process begins with entering the database password, which is set to "admin" for user access.

• To access the web interface, users must log in with the username "admin" and the configured password.

• After logging in as "Isabel," the central telephone system is successfully installed, providing an IP address (192.168.250.14) for local network access.

Accessing the Web Interface

• Users are instructed to enter the provided IP address into their browser; initial connection attempts may result in errors but will eventually succeed.

• Upon first access, users need to click on "Advanced" and proceed despite security warnings to reach the login page.

DHCP Configuration

• The server assigns an IP via DHCP; however, it can be changed to a static IP through console settings for consistent access.

• Users are cautioned that turning off their virtual machine will change the assigned IP address.

Softphone Installation

• A softphone application is required for making calls; users are directed to download "SIPer," compatible with Windows and Android systems.

• The installation process involves accepting terms and proceeding through setup steps until completion.

Creating Extensions

• In configuring extensions within the PBX system, users navigate to PBX settings and add new extensions by submitting user details like extension number (e.g., 7001).

• Password fields can be left blank during extension creation; changes must be applied for them to take effect.

Finalizing User Accounts

• Users create additional extensions (e.g., 7002), specifying names relevant to device types (like Android phone).

Configuration of a VoIP Phone System

Setting Up the Windows Phone

• The phone is configured to connect to a server using port 7001, with the domain set for the central telephone system.

• The IP address used for configuration is 192.168.250.14, and a password is set that is unique to the administrator rather than the end user.

• After entering the necessary information, clicking "login" prompts for the server's domain name or IP address before proceeding with setup.

• The connection method selected is UDP, which allows for efficient communication between devices on the network.

Installing and Configuring on Android

• To install on Android, users search for "siiper," specifically opting for the Beta version of the application.

• Configuration mirrors that of Windows; users input extension number 7002 and again use IP address 192.168.250.14 along with their previously set password.

• It’s clarified that this password remains consistent across different devices (Windows and Android), ensuring ease of account management.

Finalizing Setup and Testing Calls

• Once all configurations are complete, users create an account in siiper, confirming service provider details without needing additional proxy settings.

• Upon successful connection via UDP, users can finalize setup by accepting any permissions required by the app.

• A test call from Android to Windows (extension 7001) confirms functionality; subsequent calls are made in both directions to ensure operational integrity.
