CDR History

Storage of Call Detail Records (CDR) for all calls (or call attempts) that are passed via Yeti. Yeti save CDR for every call termination attempt, so one received call on legA can cause multiple CDRs in case of rerouting.

All CDRs related to one call will have same values of Time Start, Orig Call Id and Local tag. routing attempt value indicates sequence number of CDR withing same call.

INFO

There is built-in tool to provide CDR data retention, see Data retention documentation.

WARNING

Do not use the built-in ActiveAdmin Download CSV link to export large amounts of CDRs — it runs synchronously in the Rails process and will time out or exhaust memory. Use the CDR Export tool instead.

CDR attributes

Id

Unique CDR identifier.

UUID

Globally unique identifier for this CDR record, generated as a time-based UUID (v1) at the moment the CDR is written. Unlike the numeric Id (an internal database sequence), the UUID is stable across exports, API responses, and external integrations, making it suitable for referencing CDRs in external billing or analytics systems.

Metadata

Metadata

JSON object that aggregates supplementary call data collected during routing. It is built by merging contributions from multiple sources:

Key	Source	Description
vars	Call variables	Object containing all variables assigned to the call during routing stages (Customer Auth, Numberlists). Present only when at least one variable was assigned.
cnam_resp	CNAM Database Response Lua script	Arbitrary data returned by the CNAM lookup metadata field. Present only when a CNAM lookup was performed and the response Lua script returned a non-null metadata value.

Example with both sources populated:

{
  "vars": {
    "r1r2": "000",
    "insee": "12345"
  },
  "cnam_resp": {
    "provider_id": "abc",
    "cached": true
  }
}

INFO

The metadata field is only visible to users with the allow_metadata permission.

STIR/SHAKEN attributes

LegA SS Status

STIR/SHAKEN attestation status of the Identity header received on legA. Set by the SS Mode configured on the matched Customer Auth. Possible values:

Value	Meaning
None	No Identity header was present, or STIR/SHAKEN processing is disabled.
Invalid	An Identity header was present but signature validation failed (bad signature, number mismatch, or certificate error).
A	Full attestation — the signing provider authenticated the caller and their right to use the calling number.
B	Partial attestation — the signing provider authenticated the call origination but cannot verify the caller's right to use the number.
C	Gateway attestation — the call originated from a gateway and full attestation is not possible.

LegB SS Status

STIR/SHAKEN attestation status of the Identity header sent to the termination gateway on legB. Set by the STIR/SHAKEN Mode configured on the termination Gateway. If the incoming legA identity was valid, it is relayed and this value equals LegA SS Status. If a new identity was signed by Yeti, this reflects the attestation level of the generated signature.

LegA Identity

Full parsed content of the Identity header received from the origination gateway on legA, stored as a JSON object. Contains the decoded PASSporT claims including attestation level (attest), originating number (orig.tn), destination number (dest.tn), and timestamp (iat). Present only when an Identity header was received and successfully parsed.

RTP Diagram

The CDR show page has an RTP statistics tab with an interactive diagram of the RTP streams that belong to the call. It draws the origination gateway, the Yeti SBC and the termination gateway(s), with arrows representing each RTP stream and its direction of audio flow. A separate termination node is drawn per routing attempt, so re-routed attempts are shown side by side. Clicking a stream opens a panel with the full RX/TX stream record.

Streams are correlated with the CDR by Local Tag / LegB Local Tag and the shared Time Start, so the diagram aggregates the media of all routing attempts of the call. See RTP Statistics for the diagram layout and the meaning of every stream attribute.

INFO

The tab shows "No RTP streams found for this CDR." when the call carried no media (e.g. it was rejected before connect) or when its RTP statistics were collected by an older Yeti version that did not store the CDR Time Start on the stream rows.
