3. Asterisk configuration file

The Asterisk configuration file, asterisk.conf, contains a wealth of information about the Asterisk system, including the Asterisk version. The version number is stored in the VERSION= parameter, which can be found near the beginning of the file.

Checking the Asterisk version in the configuration file is a reliable method that provides direct access to the source of configuration. It is particularly useful when other methods, such as the asterisk -version command or the GUI, are not available or produce unexpected results.

To check the Asterisk version in the configuration file, open the asterisk.conf file in a text editor and locate the VERSION= parameter. The value of this parameter is the Asterisk version number.

For example, if the asterisk.conf file contains the following line:

VERSION=18.12.0

Then the Asterisk version is 18.12.0.

Knowing how to check the Asterisk version in the configuration file is a valuable skill for system administrators and users who need to access the Asterisk version information directly from the configuration source.

4. RPM package

This section dives deeper into the connection between using RPM packages to check the Asterisk version and the broader context of “how to check asterisk version”. It explores the relevance of RPM packages in this context and provides a comprehensive understanding of their role in managing Asterisk versions.

• Package management
  RPM packages are essential for managing software on RPM-based systems, including Asterisk. They provide a standardized and automated way to install, update, and remove software, ensuring system stability and consistency.
• Version tracking
  RPM packages maintain detailed information about the software they contain, including the version number. This information is stored in the RPM package metadata and can be easily accessed using the rpm -qi command.
• System-wide visibility
  RPM packages provide a centralized mechanism for managing software versions across the entire system. By checking the RPM package information, administrators can quickly determine the Asterisk version installed on the system, regardless of where it was installed from.
• Consistency and reliability
  Using RPM packages to check the Asterisk version ensures consistency and reliability. The rpm -qi command provides accurate and up-to-date information about the installed software, eliminating the risk of errors or inconsistencies that may arise from manual methods.

In conclusion, understanding the role of RPM packages in checking the Asterisk version is crucial for effective Asterisk management on RPM-based systems. RPM packages offer a standardized and reliable way to track and manage software versions, providing system administrators with a valuable tool for maintaining and updating their Asterisk systems.

5. Docker image

When Asterisk is deployed in a Docker container, the Asterisk version is embedded in the Docker image tag. This provides a convenient way to check the Asterisk version without having to access the container or the underlying host system.

To check the Asterisk version using the Docker image tag, you can use the following steps:

1. List the available Docker images using the docker images command:“`docker images“`
2. Identify the Asterisk image by its name or ID.
3. Check the image tag, which typically follows the image name and is separated by a colon (:). The image tag contains the Asterisk version.

For example, if the following Docker image is listed:

asterisk/asterisk:18.12.0

Then the Asterisk version running in the container is 18.12.0.

Knowing how to check the Asterisk version using the Docker image tag is essential for managing Asterisk deployments in containerized environments. It allows system administrators to quickly and easily determine the Asterisk version running in each container, facilitating version control, updates, and troubleshooting.
