VoipNow VMware OVA Deployment Guide

This page contains instructions on how to deploy the VoipNow OVA on VMware vSphere.

Requirements

We highly recommend VMware vSphere 8.0 or newer versions for production environments.

To meet VoipNow's performance and computing requirements, the virtual machine must have the following configuration:

• Memory: 16GB (or more)
• CPUs: 4 cores (or more)
• Network adapter: VMXNET 3 (1GbE or more)
• HDD: 50GB virtual disk (or more)

"Resource reservation required"

For proper VoIP functionality, at least 25% of CPU and RAM must be reserved for the VoipNow.

Important Notes

"⚠️ DHCP Recommended"

VoipNow IP settings are configured during first boot. If you use a static IP or if the IP address changes after first boot, you must manually update the IP in the VoipNow web interface (Cloud Management section).

"Firewall / security group ports"

Make sure the VM firewall (and any upstream firewall/security group) allows:

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

OVA Deployment

1. Deploy the OVA

   Download the VoipNow OVA from https://repo.4psa.com/download/, then in vSphere, choose Deploy OVF Template, select the VoipNow OVA (local file), then click through the wizard.

2. Choose placement

   Select the name, folder, and host/cluster.

3. Configure storage & networking

   Pick the datastore (thin provision recommended) and map the network.

4. Customize template (optional credentials)

   Field	Description
   Root Password	Linux root password
   VoipNow Password	Web admin password
   SSH Public Key	SSH public key for root

   ""

   Leave fields empty to skip setting that credential. These are applied on first boot only.

5. Finish & power on

   Review settings, click Finish, then power on the VM (or select Power on after deployment).

6. Access VoipNow

   Open https://<VM-IP> and log in with the admin credentials.

""

The first boot will take longer than usual (about 5–10 minutes). Please wait for initialization to complete before taking further action.

OVF Properties Reference

Property	Description
Root Password	System root password (Linux)
VoipNow Password	VoipNow web admin password
SSH Public Key	SSH public key for root user

"Where to configure these"

If you need to change them later, edit the VM and look for the OVA/OVF Properties (often under vApp Options / OVF environment in vSphere).

Behavior:

• Only non-empty values are applied
• Empty fields are ignored (no changes made)
• Properties are applied once on first boot only
• A flag file /var/lib/ovf-properties-applied prevents re-application on subsequent reboots
