Rebuilding VICIdial conf files after changes
VICIdial regenerates Asterisk config from the database. Here is what the rebuild conf files step does, when it fires, and how to trigger it safely.
Running the VICIdial database on its own server
Splitting MySQL onto a dedicated database server frees the telephony box for Asterisk and opens the door to replication. Here is when and how to do it.
Installing audio codecs (g729 and friends) for VICIdial
G711 ships free with Asterisk; g729 and g723 are licensed. Here's what each codec costs in bandwidth, why g729 needs registration, and how to install it cleanly.
Going from zero to a running dialer in under a minute
Pay, and in under 40 seconds you have a dedicated VPS running secured VICIdial on a branded HTTPS subdomain with root SSH. Bring your SIP carrier and start dialing.
How to run VICIdial on Hetzner Cloud
A practical walkthrough of running VICIdial on a Hetzner Cloud VPS: instance type, public IPv4, the firewall rules for SIP and RTP, snapshots, and the audio caveats.
The VICIdial keepalive scripts and crontab
VICIdial keeps its dialer alive with a set of AST Perl scripts run from cron every minute. Here is what each one does and how the crontab holds the dialer up.
How long a VICIdial install really takes
A clean VICIdial install runs 45 minutes if everything cooperates and a weekend if it doesn't. Here's where the time actually goes — and the managed alternative.
Load balancing across VICIdial servers
Load balancing spreads agent and web traffic across telephony nodes in a VICIdial cluster. Here is what balances, what does not, and where the limits are.
A backup strategy for a VICIdial server
A real VICIdial backup covers three things: the database, the recordings, and the config. Here is what to dump, how often, and where to keep it.
Running a VICIdial database schema upgrade
When VICIdial code expects new columns, you run the upgrade SQL script to bring the schema forward. Here is what the ALTER scripts do and how to run them safely.
How to run VICIdial on AWS
Running VICIdial on AWS EC2: instance sizing, the Elastic IP for the public-IP requirement, security groups for SIP and the RTP UDP range, EBS for recordings, and the cost reality.
Common VICIdial install errors and fixes
The install errors that actually stop a VICIdial build — missing Perl modules, Asterisk compile failures, MySQL grant problems, and SELinux — and how to clear each one.
Installing VICIdial on a VPS
A VPS is a fine home for VICIdial if you get three things right: a real public IP, an open RTP range, and NAT handled. Here's how each one bites.
Running SVN trunk vs a stable VICIdial release
Trunk gets the newest VICIdial fixes and features first, but a tagged release is tested and predictable. Here is how to pick the right one for a production dialer.
Self-installing VICIdial vs managed hosting
Self-install gives you full control and a real learning curve. Managed hosting gives you the same VICIdial in under 40 seconds. Here's the honest trade-off.
Running VICIdial in the cloud: the complete guide
Why teams move VICIdial to the cloud, the per-provider landscape, the universal gotchas, and how BYOI and managed hosting compare for a working dialer.
How to upgrade VICIdial safely
Upgrading VICIdial is backup, then svn update, then the database upgrade script, then test. Do it in that order on a snapshot you can roll back to.
Sizing a VICIdial server for your agent count
VICIdial sizing comes down to concurrent calls, not just agents. Here is how to estimate cores, RAM, and disk from your dial ratio and agent count.
How to run VICIdial on Google Cloud
Running VICIdial on Google Cloud Compute Engine: machine type, an external static IP, VPC firewall rules for SIP 5060 and RTP 10000-20000, persistent disk, and NAT audio.
Moving VICIdial to new server hardware
Migrating VICIdial to a new box is five jobs: dump the database, sync recordings, cut over the IP and DNS, rebuild the config, and re-register your trunks.
Setting up a VICIdial archive server
An archive server pulls old recordings and call logs off the dialer box so disk pressure never slows your live campaigns. Here is how to set one up.
Web server vs telephony server roles
In a multi-server VICIdial, the web role runs Apache and PHP while the telephony role runs Asterisk. Here's what each does and why splitting them matters.
Personalizing VICIdial after a fresh install
A fresh VICIdial install boots generic. Set the timezone, server IP, passwords, branding, and a first campaign before you ever dial a live number.
Setting the server time zone and NTP for VICIdial
VICIdial enforces call times and stamps every report by the server clock. Set the OS time zone, point at NTP, and match the GMT offset in System Settings.
