Installation

There are several ways to install and deploy your system. Depending on your infrastructure, budget, and technical expertise, you can choose from one of the following installation methods.

Note:
The Call Center module must be installed with the PBX and cannot operate without it. Ensure that PBX services remain active.

1. Plug and Play Appliance – Ideal for quick setups without technical complexity.
2. Bare-Metal Server – Install the system by uploading an OVA file or running a script over Debian.
3. Private Cloud (Hyper-V, VMware, etc.) – Deploy via OVA or install manually with a script.
4. Public Cloud (AWS, Azure, etc.) – Use OVA or launch via marketplace images like AMI (for AWS).

1️⃣ Plug and Play Appliance

Description

Pre-configured system appliances come with the OS and system installed. Just connect to power and network to begin.

Steps

1. Unbox and place the appliance in a secure location.
2. Connect power and network cables.
3. Access web UI via IP shown on LCD or from the router’s DHCP.

2️⃣ Bare-Metal Server Installation

Description

Install the system directly on physical hardware by importing an OVA or running a script over Debian. Best for high-performance or on-premise needs.

Option A: Deploy Using OVA/ISO Image

Steps

1. Download the latest system OVA file.
2. Use tools like Rufus or Etcher to create a bootable USB (for ISO).
3. Boot your physical server from the USB.
4. Follow on-screen installation instructions.

Option B: Script-Based Installation on Debian

Steps

1. Install Debian Server.
2. Update the system:

sudo apt update 

3.Download and run the system installation script:

wget https://xontel.com/install.sh && bash install.sh

4. Access the system via the web UI and complete the setup.

3️⃣ Private Cloud Deployment

Description

Run system in your private cloud using Hyper-V, VMware, or similar. Offers control, flexibility, and scalability within your internal infrastructure.

Supported Platforms

• VMware vSphere / ESXi
• Microsoft Hyper-V
• Proxmox, Nutanix, and others

Option A: OVA Deployment

Steps

1. Download the system OVA file from the official source.
2. Import the OVA into your virtualization platform:
   • VMware vSphere/ESXi: Use the vSphere Client to deploy the OVA.
   • Microsoft Hyper-V: Convert the OVA to VHDX using tools like StarWind V2V or qemu-img, then create a new VM.
   • Proxmox: Convert and import the OVA to a compatible format (e.g., qcow2 or raw).
3. Configure VM resources:
   • CPUs, RAM, Storage
   • Network
4. Start the VM and access the system web interface via the assigned IP address.

Option B: Script-Based Installation on Debian VM

Steps

1. Create a new virtual machine in your private cloud environment.
2. Install Debian Server.
3. Update the OS:

sudo apt update

4.Download and run the system installation script:

wget https://xontel.com/install.sh && bash install.sh

5. Access the system web interface via the assigned IP address.

6. Complete setup via the web interface after installation.

4️⃣ Public Cloud Deployment

Description

Deploy the system on platforms like AWS or Azure using an OVA or official AMI. Ideal for remote access, global scalability, and high availability.

Supported Platforms

• AWS – Use available AMI or upload OVA.
• Azure – Upload VHD or OVA and deploy via custom image.
• And other platforms

Note:
You can choose to install the system in one of two ways:

• Hosted by XonTel: Let XonTel manage the hosting and infrastructure for you.
• Self-hosted: Deploy the system on your own cloud server for full control.

Upload and Deploy OVA

Steps

1. Convert OVA to a supported format (e.g., VHD for Azure).
2. Upload via S3/Blob or import as an image.
3. Launch VM using the image.
4. Choose instance type and configure storage.
5. Configure network and security rules.
6. Access the system Web Interface by public IP.

🖥️ Call Center PBX Hardware Requirements (Based on Agent Count)

Agent Count	Concurrent Calls (Est.)	CPU (vCores)	RAM	Storage
10–25	10–20	2 cores	4 GB	40–80 GB SSD
25–50	20–40	4 cores	8 GB	80–120 GB SSD
50–100	40–80	6–8 cores	12–16 GB	120–250 GB SSD/RAID
100–200	80–150	8–12 cores	16–24 GB	250–500 GB SSD RAID
200–500	150–300+	16+ cores	32+ GB	500 GB – 1 TB SSD RAID

🎙️ If using call recording or voicemail:

• Add 50–100 GB+, depending on call duration.

🔄 If transcoding is required (e.g., G.729, G.722):

• Requires more CPU power (Asterisk uses floating-point operations).
