; Asterisk Call Detail Record Logging (CDR) - Custom DSV Backend
;

; This is the configuration file for the customizable DSV backend for CDR
; logging.
;
; DSV??  Delimiter Separated Values because the field delimiter doesn't have
; to be a comma.
;
; Legacy vs Advanced Mappings
;
; Legacy mappings are those that are defined using dialplan functions like CDR
; and CSV_QUOTE and require a VERY expensive function replacement process at
; runtime for every record output.
;
; Advanced mappings are those that are defined by a list of field names and
; parameters that define the field separator and quote character you want to use.
; This type of mapping is uses significantly less resources at runtime.
;
;
; Legacy Mappings
;
; Within a legacy mapping, use the CDR() and CSV_QUOTE() functions to retrieve
; values from the CDR.
;
; NOTE: If your legacy mapping uses commas as field separators and only the CSV_QUOTE
; and CDR dialplan functions, the module will attempt to strip the functions and
; and create a much faster advanced mapping for it. However, we urge you to create
; a real advanced mapping and not rely on this process. If the mapping contains
; something not recognized it will go the slower legacy route.
;
; Each entry in the "mappings" category represents a separate output file.
; A filename that starts with a forward-slash '/' will be treated as an absolute
; path name.  If it doesn't, it must be a file name with no directory separators
; which will be placed in the /var/log/asterisk/cdr-custom directory.

;
; Advanced Mappings
;
; Each category in this file other than "mappings" represents a separate output file.
; A filename that starts with a forward-slash '/' will be treated as an absolute
; path name.  If it doesn't, it must be a file name with no directory separators
; which will be placed in the /var/log/asterisk/cdr-custom directory.

;format = dsv                 ; Advanced mappings can actually have two types
                              ; "dsv" or "json".  This example uses "dsv", which
                              ; is the default, but see the example below for more
                              ; info on the json format.

;separator_character = ,      ; The character to use for the field separator,
                              ; It defaults to a comma but you can use any
                              ; character you want.  For instance, specify
                              ; \t to separate the fields with a tab.

;quote_character = "          ; The character to use as the quote character.
                              ; It defaults to the double quote but again, it
                              ; can be any character you want although the
                              ; single-quote is the only other one that makes
                              ; sense.

;quote_escape_character = "   ; The character to use to escape the quote_character
                              ; should the quote character actually appear in the
                              ; field output.  A good example of this is a caller
                              ; id string like "My Name" <1000>.  For true CSV
                              ; compatibility, it must be the same as the quote
                              ; character but a backslash might be acceptable for
                              ; other formats.

;quoting_method = all         ; Nothing says you _have_ to quote anything. The only
                              ; time a field MUST be quoted is if it contains the
                              ; separator character and this is handled automatically.
                              ; Additionally, the following options are available:
                              ; "all": Quote all fields. The default.
                              ; "non_numeric": Quote all non numeric fields.
                              ; "none": Don't quote any field (unless it contains
                              ; a separator character).

;fields = clid,"Some Literal",src, dst, dcontext, channel, dstchannel, lastapp, lastdata, start, answer, end, duration, billsec, disposition, amaflags, accountcode, uniqueid(noquote), userfield, sequence,ds_type(uservar)
    ; This is the list of fields to include in the record. The field names are the
    ; same as in the legacy mapping but without any enclosing dialplan functions.
    ; You can specify literals to be placed in the output record by double-quoting
    ; them. There is also some special notation available in the form of "qualifiers".
    ; A qualifier is a list of tags, separated by the '^' character and placed
    ; directly after the field name and enclosed in parentheses.
    ;
    ; All fields can accept the "quote" or "noquote" qualifier when you want to exempt
    ; a field from the "quoting_method" policy.  For example, when quoting_method=all,
    ; you can force the uniqueid field to not be quoted with `uniqueid(noquote)`. The
    ; example in fields above shows this.
    ;
    ; If you've added user variables to the CDR using the CDR() dialplan function in
    ; extensions.conf, you'll need to retrieve the field using the "uservar" qualifier.
    ; For example, if you've added the "ds_type" variable, you'll need to retrieve
    ; it with `ds_type(uservar)`.
    ;
    ; The default output format for the "start", "answer" and "end" timestamp fields
    ; is the "%Y-%m-%d %T" strftime string format however you can also format those
    ; fields as an int64 or a double: `start(int64)` or `start(double)` or
    ; provide your own strftime format string: `start(%FT%T%z)`.
    ;
    ; The "disposition" and "amaflags" are formatted as their string names like
    ; "ANSWERED" and "DOCUMENTATION" by default but if you just want the numbers and
    ; not the names...  `amaflags(int64),disposition(int64)`.
    ;
    ; If you need to combine flags, use the caret '^' symbol: `start(int64^noquote)`
    ;
    ; Final notes about "fields":
    ;    Field names and qualifiers aren't case sensitive.
    ;    You MUST use the comma to separate the fields, not the "separator_character".
    ;    You MUST use the double-quote to indicate literal fields, not the "quote_character".
    ;    Whitespace in "fields" is ignored except in literals.

;
; An Advanced JSON example:
;
;[cdr_master.json]
;format = json
;fields = clid,"My: Literal",src, dst, dcontext, channel, dstchannel, lastapp, lastdata, start, answer, end, duration, billsec, disposition, amaflags, accountcode, uniqueid(noquote), userfield, sequence,ds_type(uservar)
;
;  In order to ensure valid JSON, the following settings are forced:
;    The separator character is always the comma.
;    The quote character is always the double-quote.
;    The quote escape character is always the backslash.
;    The quoting method is always "non_numeric".
;
;  Since JSON requires both a name and value, the name is always
;  the field name.  For literals however you must specify the literal
;  as a "name: value" pair as demonstrated above.  The output record
;  would then look something like:
; {"clid":"\"Alice\" <1000>", "My":"Literal","src":"1000","dst":"18005551212", ...}
