Reference7:Call Detail Record CDR PBX

If enabled the PBX generates Call Detail Records (CDR) for each call and each object, which means if a call is made from one user to another a CDR for an outgoing call is generated at the first user object and a CDR for an incoming call is generated at the other user object. The CDRs are generated at the end of the call and sent via the CDR0 and CDR1 interfaces. XML is used for the content of the CDRs.

Version

This feature is availabe starting with version 7.00.

Content

Top-Level Tag <cdr>

Each CDR uses the top-level tag <cdr>. The following attributes are used with this tag:

guid	The GUID identifying the object this call belongs to.
cn	The cn (Long Name) of the object
e164	The Number of the object
h323	The H.323 Id (Name) of the object
dir	Indicates the direction of the call. For a call originating from this object this attribute is set to from. For calls sent to this object this attribute is set to to
utc	The time when this call was started as UTC time. This is an integer with the standard ctime semantic.
local	The local time the call was started.

The Tag <event>

For each state a call goes thru a tag <event> is added to the CDR. The following attributes are used with this tag:

msg	A string identifying the message which caused the state change of the call
time	The time in seconds from the beginning of the call
e164	The number of the other party of the call if available
h323	The H.323 Id (Name) of the other party of the call if available
conf	A GUID identifying the call (conferenceID). This GUID can be used to associated CDRs from outgoing calls to the CDRs of incoming calls even across different PBXs. The first event within a CDR always contains this attribute. The conferenceID may change during a call (e.g. because of a call transfer). In this case another conf attribute is present containing the new conferenceID.
