Installation

...

OS Recommendation

For all new installations, we strongly recommend the Red Hat Enterprise Linux 7 Update 8.x or CentOS 78.1 x running on 64 bit.  Before Before proceeding with the installation of VoipNow on a new server:

  • Make sure you have reviewed the the Release Notes, as they always contain important advice regarding the upgrade.
  • Check if the date and time on that server are correct. Using a NTP service to keep the clock synchronized is required.

Download and run the installer

To install VoipNow:

  1. Log in to your server as root using SSH from any client operating system.
  2. Download the installer script on your server by executing the command below.

    Shell
    curl "http://www.4psa.com/software/
    voipnow35installer
    voipnowinstaller.sh" -o voipnowinstaller.sh -L
  3. Run the installer script by executing the following command.

    Shell
    sh voipnowinstaller.sh
Tip
titleCoffee Break!

Wait patiently as the installer downloads all the packages from the repository, installs them, and configures the system.

Optional components

PSTN interface card drivers

During the setup process, the VoipNow Installer asks if you want the Dahdi kernel drivers to be configured.

This is strictly necessary only if you installed an ISDN PRI interface card to the server. Otherwise, installing Dahdi drivers is not recommended.

Tip

Most installations do not use ISDN interfaces, as this method of interacting with the PSTN network is obsolete.

Upgrade

Before you start

There is not much to do, but do it properly:

VoipNow 5.x upgrade notes

If you're upgrading to VoipNow 5.x from VoipNow 4.1.3 or a previous version, please run the database upgrader as specified in the Release Notes.

Before you start

Make sure that you understand the implications of the upgrade.

  • Your hardware configuration must meet the hardware requirements of the newer version, if these have changed. Check them out before initiating the upgrade process.
  • During a software upgrade process, all phone calls are might be dropped. Consequently, it is recommended that you perform such upgrades outside business hours.
  • The upgrade might take several minutes, especially on systems with large databases.  DO NOT interrupt the VoipNow Installer by installer by pressing CTRL-C or rebooting the system, as your upgrade might become inconsistent!
  • The upgrade process will take longer if there are many CDRs on the system. This happens because tables are converted from MyISAM to INNODB and it only occurs once, when upgrading from VoipNow 3 to VoipNow 3.5. To avoid this conversion, run export DONOT_INNODB=1 before executing the installer.call history records in the database.

Download and run the installer

To upgrade VoipNow:

  1. Log in to your server as root using using SSH from from any client operating system.
  2. Download the latest installer script on your server by executing the command below.

    Shell
    curl "http://www.4psa.com/software/
    voipnow35installer
    voipnowinstaller.sh" -o voipnowinstaller.sh -L
  3. Run the installer script by executing the following command.

    Shell
