This guide contains instructions on how to install VoipNow on a single computing node or upgrade the software deployed on a single node.

Fast Track

If you want to skip reading this document, you can go and use the Command Line Installer.

It provides adequate support for all environments.

Compatibility

Hardware compatibility list

Before you start the installation, make sure that your hardware is supported by checking the Hardware Compatibility List (HCL).

By using virtualization, you do not need to worry anymore about the hardware your virtual machine runs on!

Virtualization

VoipNow is designed to take advantage of server virtualization techniques. Virtualization is at the foundation of cloud services and VoipNow is a software system designed for the cloud.

Therefore, we strongly recommend to install VoipNow in a virtualized environment. We support VMware vSphere, Virtuozzo, OpenStack or Citrix XenServer.

Virtualization brings many management advantages, as well as superior resource abstraction and disaster recovery capabilities.

All public cloud services use virtualization. If you use such a cloud service, it's not important what technology is used.

Operating system

VoipNow is compatible with the Linux distributions:

  • Red Hat Enterprise Linux 7.x and newer (x86_64), 
  • Red Hat Enterprise Linux 8 (x86_64)
  • CentOS 7.x (x86_64)
  • CentOS 8 (x86_64)

Installation

VoipNow can be installed in multiple ways, based on your environment and requirements. You will find all possible options below.

Your own infrastructure

We assume that you have access to your server in one of the following ways:

  • direct or remote access to physical machine
  • access to a virtualized environment running on a physical machine controlled by a third-party

This usually happens when you are managing you own private cloud.

No operating system installed

Virtualize your server first using one of the recommended virtualization techniques. Once you have virtualized your machine, you can:

If you do not want to use virtualization at all, or you use any other bare metal virtualization software, you can use the ISO image. Find out how it's done.

Operating system installed

If the operating system is supported by VoipNow, you must use the Command Line Installer.

Upgrade

Plan the upgrade

To guarantee the success of a system upgrade, make sure you:

  • Review the Release Notes - Make sure that all software improvements are clear. If you need further details, do not hesitate to ask a question in our community.
  • Test the new version - If you upgrade from an old version, it's always a good idea to install VoipNow on a test environment and make sure that it works as expected.

  • Schedule the upgrade - Because the software upgrade might temporary affect services, it is highly recommended to perform the upgrade outside business hours.

Perform the upgrade

The upgrade process depends on your installation environment.

VMware vSphere

You must execute the VoipNow Command Line Installer or schedule the upgrade from the VoipNow web management interface.

Virtuozzo

If you installed VoipNow using the Virtuozzo templates and root access to Virtuozzo machine is available, you can upgrade using the Virtuozzo templates. Otherwise, you must execute the VoipNow Command Line Installer or schedule the upgrade from the VoipNow web management interface.

Citrix XenServer

You must execute the VoipNow Command Line Installer or schedule the upgrade from the VoipNow web management interface.

Any other bare metal or cloud environment

You must execute the VoipNow Command Line Installer or schedule the upgrade from the VoipNow web management interface.
