With over a decade of experience in deploying call center solutions, I've seen firsthand how a well-configured VICIdial system can transform operations.

This guide provides a clear, step-by-step path to install VICIdial, configure it for optimal performance, and secure it against vulnerabilities, catering to both beginners and seasoned administrators. From single-server setups to VICIdial cluster configurations and cloud deployments, we'll cover everything you need.

Understanding VICIdial and Installation Options

What is VICIdial?

VICIdial is an enterprise-grade, open-source contact center suite used by thousands of call centers worldwide. It's a powerhouse for predictive dialing, inbound call handling, blended campaigns, and even advanced features like IVR, CRM integration, and website chat. Unlike proprietary solutions, VICIdial offers unparalleled customization.

A common point of confusion is the difference between VICIdial and ViciBox. VICIdial is the core contact center software. ViciBox, on the other hand, is an OpenSuSE-based installer that bundles VICIdial with essential dependencies like Asterisk (telephony engine), MariaDB (database), and Apache (web server).

Hardware and Software Requirements

For a VICIdial single server setup (ideal for 15–20 agents), you'll need: 4-core CPU, 8GB RAM minimum, 250GB RAID1 SSD, stable internet with static IP. For a VICIdial cluster (50+ agents), consider separate database, web, and telephony servers with higher specs.

System Requirements and Prerequisites

• CPU: 4-core processor (Intel Xeon or AMD Ryzen). For clusters, 8+ cores.
• RAM: 8GB minimum (16GB recommended). For clusters, 16GB+ for database server.
• Storage: 250GB RAID1 SSD (SSD preferred for database performance).
• Network: Stable internet with at least 100 Mbps bandwidth and a static IP.
• OS: OpenSuSE Leap (for ViciBox) or Alma Linux/CentOS (for scratch install).

Using ViciBox ISO for Single-Server Setup

Step 1: Download and Prepare the ViciBox ISO
Visit http://download.vicidial.com/iso/vicibox/server/ and download ViciBox v.9.0.3 ISO. Verify checksum.

Step 2: Boot and Install ViciBox
Boot from ISO, select "ViciBox OEM Install", choose "Express" installation.

Step 3: Run the VICIdial Installer
Log in as root, run vicibox-install, select Y for all components.

vicibox-install

Step 4: Configure Network Settings
Set static IP in /etc/sysconfig/network/ifcfg-eth0 and run update_server_ip.

Step 5: Verify Installation
Access admin interface at https://your_server_ip/vicidial/admin.php (default: 6666/1234).

Scratch Install on Alma Linux or CentOS

For advanced users who prefer full control, use Carpenox's auto-installer scripts from GitHub:

cd /usr/src
git clone https://github.com/carpenox/vicidial-install-scripts
cd vicidial-install-scripts
chmod +x standard-db.sh
./standard-db.sh

This configures VICIdial with pre-set campaigns and users. Update phone logins by adding "a" (e.g., 101 becomes 101a).

Cloud-Based VICIdial Setup

Launch a cloud instance (AWS EC2, DigitalOcean Droplet) with Alma Linux 9, 4 vCPUs, 8GB RAM, 250GB SSD. Configure security groups to allow ports 80, 443, 5060, 10000-20000, and 8089. Install using the scratch install method above.

Configuring VICIdial

Setting Up SIP Trunks and Carriers

In the admin interface, go to Admin > Carriers > Add a New Carrier. Configure your SIP provider settings. Example sip.conf entry:

[trunk_1]
type=friend
host=sip.your_provider.com
username=your_username
secret=your_password
dtmfmode=inband
disallow=all
allow=ulaw
allow=alaw
qualify=1000

Configuring Campaigns, Users, and Leads

Create a campaign (Campaigns > Add a New Campaign), add users (Admin > Users), and load leads via CSV (Lists > Load New Leads).

Integrating Softphones (EyeBeam, WebRTC)

For WebRTC ViciPhone, ensure SSL is enabled and configure WebSocket URL in Admin > Servers.

Securing Your VICIdial Installation

• Firewall: Open only required ports (80,443,5060,10000-20000,8089). Restrict SSH to office IP.
• SSL Certificates: Install Let's Encrypt using CertBot: certbot --apache -d your_domain.com.
• Dynamic Portal: Enable in Admin > System Settings and whitelist allowed IPs.
• MariaDB Hardening: Run mysql_secure_installation and create dedicated database user.

Setting Up a VICIdial Cluster

For 50+ agents, deploy separate database, web, and telephony servers. Install ViciBox on each with appropriate role. Configure database server to allow connections from web/telephony servers. Add servers in Admin > Servers.

Optimizing VICIdial Performance

• Asterisk: Adjust maxcalls=500 and maxload=0.7 in asterisk.conf.
• MariaDB: Set innodb_buffer_pool_size=2G and add indexes to key tables.
• Apache: Tune mpm_prefork and enable compression/caching.
• Load Balancing: Use mod_proxy for web server load balancing.

Troubleshooting Common VICIdial Issues

• "Invalid Extension" Error: Check phone login in Admin > Phones and SIP registration.
• "Only Person in Conference" Error: Verify Asterisk is running and SIP trunk registered.
• Database Connection Errors: Check MariaDB status and credentials in dbconnect.php.
• Web Interface Access Issues: Verify dynamic portal settings and Apache status.

Backing Up and Upgrading VICIdial

Schedule daily database backups using mysqldump. For upgrades, run svn update in /usr/src/astguiclient/trunk and apply database schema changes via upgrade script.
