API : PBX : CDR History

Request

This request returns details about the path a call took through the PBX.

There are two ways to address a call. Prefer the callRef form: it is the only one that works for a call leg created by a transfer, and it returns the whole call rather than one leg of it.

Only the history of customers the user has access to is returned. Numbers the CDR list hides are hidden here as well - see Hidden numbers below.

URL	https://api.telecomx.dk/pbx/cdrhistory/ref/CALL-REF
Method	GET
Access level	VIEWER, MANAGE, OWNER if calls belongs to the customer RESELLER if customer belongs to the reseller or ADMIN.
Params	CALL-REF	`callRef` of the call, from the CDR record. URL-encode it - it contains a colon.

Returns the history of every leg of the call merged into one timeline, ordered by date. The remaining top-level fields are those of the call's first leg.

URL	https://api.telecomx.dk/pbx/cdrhistory/CALL-ID
Method	GET
Access level	VIEWER, MANAGE, OWNER if calls belongs to the customer RESELLER if customer belongs to the reseller or ADMIN.
Params	CALL-ID	SIP Call-ID of the call.

Returns the history of the single leg the call arrived on. Only calls that arrived over SIP have a Call-ID; a leg the PBX created itself has none, so this form cannot address it. Use it for calls handled before call grouping was introduced, which have no callRef.

Hidden numbers

(Changed 28-09-2026.) The call history applies the same privacy rules as the CDR list:

Secret numbers. An external caller who withheld their number (caller.privacy on the CDR) is

only shown to TX staff (RESELLER_ADMIN and ADMIN). For everybody else their number and name are blank

  in ''callerNumber''/''callerName'' - and in ''calleeNumber''/''calleeName'' where a transfer made them
  the callee of a leg - and replaced by ''[hidden]'' in ''action'', which quotes numbers and names
  verbatim. A caller on one of the customer's own extensions is never hidden.
* **Sensitive numbers.** A call to or from 112, 114, 116111 or 1888 is only shown to ADMIN. For everybody
  else the number is **n/a**, the name is blank and the number is replaced by ''[hidden]'' in ''action''.
* **CPR numbers** picked up as a caller or callee name are removed for everybody.

Whether a caller is secret is recorded on the call's CDR, not in the history. A history whose CDR can no longer be found is therefore refused with 404 for users below RESELLER_ADMIN, rather than served unchecked.
