OperationId:ReadCallTraceByCdrDomain

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, structured JSON for your own viewer, with no event envelope.

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 CDR must also name {domain} as a party domain, or the answer is 404.

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.

It is the same call as GET /domains/{domain}/cdrs/{id}/sipflow. To share the trace, use POST /domains/{domain}/sipflow/{id}/store.
