How to Install VICIdial: Step-by-Step Guide (2026)

Quick answer: To install VICIdial, provision a clean Ubuntu 22.04 or Rocky Linux 9 server (4 vCPU, 8 GB RAM minimum), harden the OS, install Asterisk and MySQL, run the official VICIdial install script, configure a SIP trunk, and create your first campaign. Budget 20-40 hours as a first-timer, or use a professional VICIdial installation service to be production-ready in 24 hours.

Installing VICIdial the right way is the difference between a call center that hums and one that crashes at 8am. This guide walks through the full VICIdial installation process on Ubuntu 22.04 — the same path our engineers take when installing for clients.

VICIdial Installation Methods

There are three common paths: manual install from source on Ubuntu or Rocky (covered in this guide), the prebuilt VICIbox ISO, or a fully managed hosted deployment. The easiest installation method is VICIbox, covered in our VICIbox installation guide — it bundles Linux, Asterisk, MySQL, and VICIdial into a single ISO so you can skip most of the manual steps below.

Step 1 — Prepare Your Server

Start with a clean server. VICIdial is allergic to half-configured boxes. Minimum specs for a single-server install supporting up to 50 concurrent agents:

4 vCPU / 8 GB RAM / 100 GB SSD
Ubuntu 22.04 LTS or Rocky Linux 9
A public IPv4 address
SSH root access
A dedicated carrier willing to hand you SIP credentials

Update the OS, set the hostname, set the timezone, disable unneeded services, and configure a firewall allowing SSH, HTTPS, and your SIP/RTP range.

Step 2 — Install Asterisk and Dependencies

VICIdial depends on a specific Asterisk build. Don’t use the distribution package. Instead, compile Asterisk with the VICIdial patches (chan_sip configured, MeetMe or ConfBridge selected, and the right module set). The official VICIdial installation docs list exact versions known to work.

While you’re at it, install MySQL (or MariaDB) and tune innodb_buffer_pool_size to ~50% of RAM. A stock MySQL will fall over under serious call volume.

Step 3 — Run the VICIdial Installer

Pull the VICIdial source tarball, unpack it, and run the install script. Expect the script to ask about:

Database root credentials
Whether this is a single-server or cluster node
Server IP and hostname
Web root path

Once installed, browse to https://your-server/vicidial/admin.php and log in with the default credentials. Change them immediately.

Step 4 — Configure Your First SIP Carrier

Add a carrier in VICIdial Admin → Carriers. Paste the SIP registration string from your carrier, set the dial prefix, and configure dial prefix filters for area-code routing if needed. Test with a single manual outbound call before touching a campaign.

Step 5 — Load Leads, Build a Campaign, Go Live

Create a list, import a CSV of leads (use one of VICIdial’s sample columns as a template), create a campaign, assign it to that list, and set pacing to start conservative (1.2 ratio). Have an agent log in, go into READY state, and watch the hopper tick.

Common VICIdial Installation Problems

Most installs fail on one of three things:

Carrier/SIP registration — usually firewall or NAT misconfiguration
MySQL performance — default config can’t handle the hopper queries
Audio one-way/no-way — RTP port range not open, or wrong external IP in sip.conf

Budget half a day for debugging each of these the first time through.

Skip the Learning Curve

If you don’t have 20-40 hours to learn VICIdial internals, our VICIdial installation service delivers a hardened, production-ready system in 24 hours for a flat fee. Or skip self-hosting entirely with managed hosted VICIdial plans.

Frequently Asked Questions

What OS is best for VICIdial? Ubuntu 22.04 LTS is our default recommendation for 2026 installations. Rocky Linux 9 is also well supported.

Can I install VICIdial on shared hosting? No. VICIdial needs a dedicated server or VPS with root access, custom Asterisk build, and control over firewall and kernel parameters.

How long does a first-time VICIdial install take? Plan on 20-40 hours for a first-timer going through all the documentation, firewall, and carrier testing. Experienced engineers do it in 4-8 hours.

Do I need a separate server for the database? Not for small and mid-size deployments. Past 50-100 concurrent agents, a separate MySQL server or read-replica starts to pay off.

Conclusion

VICIdial rewards careful installation. Shortcuts now mean outages later. Follow the OS prep, Asterisk build, installer, carrier, and campaign steps in order and you’ll have a working system — eventually. If “eventually” isn’t good enough, talk to us about a flat-fee installation or hosted VICIdial plans.
