3CX runs on a dedicated appliance, on a Windows or Linux server in your office, or on a cloud instance, and PBXDom works with each of these deployments the same way. You install the PBXDom collector on a Windows machine that can reach the 3CX server, register it with the license key from your account, and walk through a short wizard: choose 3CX as the vendor, 3CX General as the model, and LAN as the connection type. The collector picks up call records from 3CX over the local network and forwards them to the PBXDom cloud over standard web ports, so the only firewall requirement is outbound internet access from that one machine. Every step, with screenshots, is in How to Create a 3CX Phone System Dashboard in 10 Minutes — most installs finish in about 15 minutes.

From that point on, call records feed live dashboards showing current call traffic, abandoned calls, extension activity, and trunk utilization, with widgets you can rearrange for a team view or a wall display. Historical reports answer the longer-range questions — busiest hours, answer performance, volume by department — and can be scheduled to arrive by email daily, weekly, or monthly. Alert rules watch the same stream and notify you immediately when an extension dials 911 or another emergency number, or when calls go unanswered past a threshold you set.

Because the 3CX General profile is not tied to a specific release, it covers current 3CX versions as well as older installations still in production. Multiple 3CX instances — separate offices, or 3CX in one location and a different PBX brand in another — can all report into a single PBXDom account, which keeps multi-site reporting in one place instead of spread across each system’s own console.
