<description>

|
<para> Causes the Call Data Record to fork an additional cdr record starting from the time
|
|
of the fork call. This new cdr record will be linked to end of the list of cdr records attached
|
|
to the channel. The original CDR has a LOCKED flag set, which forces most cdr operations to skip
|
|
it, except for the functions that set the answer and end times, which ignore the LOCKED flag. This
|
|
allows all the cdr records in the channel to be 'ended' together when the channel is closed.</para>
|
|
<para>The CDR() func (when setting CDR values) normally ignores the LOCKED flag also, but has options
|
|
to vary its behavior. The 'T' option (described below), can override this behavior, but beware
|
|
the risks.</para>
|
|
<para>First, this app finds the last cdr record in the list, and makes a copy of it. This new copy
|
|
will be the newly forked cdr record. Next, this new record is linked to the end of the cdr record list.
|
|
Next, The new cdr record is RESET (unless you use an option to prevent this)</para>
|
|
<para>This means that:</para>
|
|
<para> 1. All flags are unset on the cdr record</para>
|
|
<para> 2. the start, end, and answer times are all set to zero.</para>
|
|
<para> 3. the billsec and duration fields are set to zero.</para>
|
|
<para> 4. the start time is set to the current time.</para>
|
|
<para> 5. the disposition is set to NULL.</para>
|
|
<para>Next, unless you specified the <literal>v</literal> option, all variables will be removed from
|
|
the original cdr record. Thus, the <literal>v</literal> option allows any CDR variables to be replicated
|
|
to all new forked cdr records. Without the <literal>v</literal> option, the variables on the original
|
|
are effectively moved to the new forked cdr record.</para>
|
|
<para>Next, if the <literal>s</literal> option is set, the provided variable and value are set on the
|
|
original cdr record.</para>
|
|
<para>Next, if the <literal>a</literal> option is given, and the original cdr record has an answer time
|
|
set, then the new forked cdr record will have its answer time set to its start time. If the old answer
|
|
time were carried forward, the answer time would be earlier than the start time, giving strange
|
|
duration and billsec times.</para>
|
|
<para>If the <literal>d</literal> option was specified, the disposition is copied from
|
|
the original cdr record to the new forked cdr. If the <literal>D</literal> option was specified,
|
|
the destination channel field in the new forked CDR is erased. If the <literal>e</literal> option
|
|
was specified, the 'end' time for the original cdr record is set to the current time. Future hang-up or
|
|
ending events will not override this time stamp. If the <literal>A</literal> option is specified,
|
|
the original cdr record will have it ANS_LOCKED flag set, which prevent future answer events from updating
|
|
the original cdr record's disposition. Normally, an <literal>ANSWERED</literal> event would mark all cdr
|
|
records in the chain as <literal>ANSWERED</literal>. If the <literal>T</literal> option is specified,
|
|
the original cdr record will have its <literal>DONT_TOUCH</literal> flag set, which will force the
|
|
cdr_answer, cdr_end, and cdr_setvar functions to leave that cdr record alone.</para>
|
|
<para>And, last but not least, the original cdr record has its LOCKED flag set. Almost all internal
|
|
CDR functions (except for the funcs that set the end, and answer times, and set a variable) will honor
|
|
this flag and leave a LOCKED cdr record alone. This means that the newly created forked cdr record
|
|
will be affected by events transpiring within Asterisk, with the previously noted exceptions.</para>
