GCP Cloud Deployment

This page contains instructions on how to deploy VoipNow in Google Cloud Platform (GCP).

Requirements

In order to use VoipNow in Google Cloud Platform, you need a GCP account. You can create one here.

Deployment Options

There are two ways to deploy VoipNow on GCP:

1. Terraform Infrastructure as Code - Automated deployment using Terraform modules
2. Base OS + Command Line Installer - Install VoipNow on AlmaLinux or Rocky Linux

---

Option 1: Terraform Infrastructure as Code

You can use Terraform/OpenTofu to automate the deployment process. The Terraform modules are available at https://github.com/4psa/voipnow-terraform.

The Terraform Infrastructure as Code uses VoipNow VM images available at https://repo.4psa.com/download/.

"Custom Image Creation"

You can always use VoipNow images available at https://repo.4psa.com/download/ to create your own GCE images or custom images for your cloud provider.

The module includes complete documentation, examples, and automated setup for networking, firewall rules, and VoipNow deployment.

Option 2: Base OS + Command Line Installer

You can create a VM with AlmaLinux 8 or Rocky Linux 8, then follow the Command Line Installer guide to install VoipNow.

Configure Firewall Rules

By default, GCP blocks all incoming traffic to the VM instance. You need to configure firewall rules to allow the required traffic for VoipNow.

In the Google Cloud Console, go to VPC network > Firewall. Create firewall rules to allow:

• TCP port 22 (SSH)
• TCP port 80 (HTTP)
• TCP port 443 (HTTPS)
• UDP port 5060 (SIP)
• UDP ports 10000-20000 (RTP media)
• UDP ports 4000-4999 (T.38 fax media)
• TCP port 5061 (SIP TLS)
• TCP port 25 (SMTP)

Set the Web Interface Password

We don't set any default passwords. So, you must set a password via SSH that will allow you to log in the VoipNow web interface.

After installation completes, connect via SSH using the 4psa user:

ssh 4psa@<serverip> -i <privatekey>

To gain root privileges, run the following command:

sudo su -

To set the web admin password, run the following command as root:

/usr/local/voipnow/bin/chadminpass.sh

Access the VoipNow Web Interface

You can access the VoipNow web interface at https://<serverip>

Log in using the following details:

• Username: admin
• Password: the password you set earlier
