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:
- Log in to your server as root using
SSH
from any client operating system. Download the installer script on your server by executing the command below.
voipnow35installerShell curl "http://www.4psa.com/software/ voipnowinstaller.sh" -o voipnowinstaller.sh -L Run the installer script by executing the following command.
Shell sh voipnowinstaller.sh
Tip | ||
---|---|---|
| ||
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Most installations do not use ISDN interfaces, as this method of interacting with the PSTN network is obsolete.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:
Upgrade
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 processMake sure that you understand the implications of the upgrade.
- 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.
