Managed cloud VICIdial vs a DIY cloud install
Choosing between a managed VICIdial host and a self-installed cloud setup comes down to how much engineering time you want to trade for platform fees. Here is how the two paths compare.
Read postBYOI vs a fully managed VICIdial host
Comparing BYOI and a fully managed VICIdial host means weighing infrastructure control against operational simplicity — both models keep your data on a single-tenant server.
Read postOpening the RTP port range on a cloud firewall
Cloud firewalls block inbound UDP by default, and a closed RTP port range is the most common reason VICIdial calls connect but carry no audio.
Read postCloud vs on-premise VICIdial
Choosing between a cloud VPS and an on-premise server for VICIdial comes down to who controls the hardware, who handles the ops work, and where your calls actually travel.
Read postChoosing a cloud region for your dialer
The cloud region where you deploy your VICIdial box affects call quality, data residency, and cost — here is how to pick the right one for your operation.
Read postWhy your VICIdial cloud box needs a public IP
A cloud VICIdial server without a routable public IP will fail to exchange SIP and RTP traffic with carriers, leaving agents with no audio.
Read postFree TLS certificates for a cloud VICIdial box
Let's Encrypt provides free, auto-renewing TLS certificates that secure the VICIdial agent and admin web interfaces over HTTPS on any cloud server.
Read postThe BYOI install checklist
Before a managed host can install VICIdial on your own cloud server, a handful of prerequisites need to be in place — this checklist walks through each one in order.
Read postManaging the firewall on a cloud dialer
A VICIdial cloud server's firewall needs ongoing attention — carrier IP changes, agent network shifts, and OS upgrades can all silently break SIP or RTP.
Read postKeeping carrier latency low from the cloud
Cloud region placement has a direct effect on RTP path length and call quality — here is how to reduce carrier latency for your VICIdial box.
Read postFixing NAT one-way audio in the cloud
One-way audio on a cloud VICIdial server almost always means Asterisk is advertising its private IP in SDP instead of the routable public address.
Read postSizing cloud disk for call recordings
Call recordings are the biggest disk consumer on a VICIdial box, and undersizing storage is one of the most common mistakes when moving to the cloud.
Read postTreating a cloud VICIdial box as rebuildable
The cloud mindset means designing your VICIdial setup so that destroying and recreating the server is a routine operation, not a crisis.
Read postScaling a cloud VICIdial box up for more agents
Vertical scaling on a cloud VICIdial box means resizing the VM to more vCPU and RAM, and understanding where VICIdial actually hits its limits before you resize.
Read postSnapshots and backups for a cloud VICIdial box
Cloud snapshots give you a fast path back to a known-good state, but they are not a substitute for off-box backup copies of your recordings and configuration.
Read postBring-your-own-infrastructure (BYOI) VICIdial explained
BYOI lets you supply your own cloud server while a managed host installs and operates VICIdial on it, giving you control over the hardware without taking on the full installation burden.
Read postCloud security groups for a VICIdial server
Cloud security groups default to blocking everything — this guide lists every port VICIdial and Asterisk need open and explains why each one matters.
Read postPointing a subdomain at your cloud VICIdial box
Setting up a subdomain for your cloud VICIdial box is a straightforward DNS task, and getting it right unlocks a clean HTTPS agent URL and valid TLS certificates.
Read postHow 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.
Read postHow 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.
Read postHow 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.
Read postRunning 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.
