Active calls

Live call activity across the fleet.

/dashboard/calls shows every concurrent call across every instance in your tenant in real-time. Useful for spotting capacity exhaustion or fraud spikes.

What you see

A live table grouped by instance:

Instance name + FQDN.
Caller ID (where known).
Callee — extension or trunk leg.
State — Ringing / Talking / Hold / Ended.
Started at — relative ("12 s ago", "2 m ago").

Above the table, a fleet-wide active calls count + a per-instance peak counter.

Refresh cadence

The active-calls table polls every 5 s on the page. Behind the scenes, each instance's worker poll grabs the latest CallsActive count from 3CX's SystemStatus API.

Filter by instance

Use the Instance dropdown to narrow to one PBX. Useful when diagnosing capacity issues — pair with the Call history report for trend context.

Active-call alerts

Configure a "Calls Threshold" alert in Alert routing to be paged when concurrent calls cross a percentage of licensed capacity (80% warning, 95% critical by default).
