OperationId:ReadCallTraceByCdr

Builds the trace of one call from its CDR and returns it in the rendering you pick with type. The default is call_trace_details, with no event envelope. The path names no domain, so the call only has to be in your scope.

Super User and Super User Read Only see every trace. A Reseller sees calls that have a party domain (originating, terminating, or by) in its territory. Office Manager and the other domain-tier scopes see calls that have their own domain as a party domain. User-tier scopes see only calls where their own user is the originating or terminating party. A call outside your scope answers the same 404 as a call that does not exist. A scope without the call-trace privilege gets 403; by default Office Manager, Reseller, Super User, and Super User Read Only hold it.

The documented response is JSON. The other renderings answer a file of their own media type:

type=csv&download=yes: a CSV file (text/csv)

type=call_trace&download=yes: the SVG diagram (image/svg+xml)

type=call_trace_html: an HTML viewer page (text/html); add download=yes for sip_flow_<id>.html

type=call_trace_text: plain text (text/plain)

In call_trace_text, each block header shows its time as YYYY-MM-DD_HH:MM:SS in UTC, and csv rows show the same form, with the millisecond Unix time in UnixTsm.

Prefer GET /domains/{domain}/cdrs/{id}/sipflow, which names the domain. event is not an ID here: POST /sipflow/event injects an event.
