		<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>

			<para>WaitForSilence(1000) will wait for 1 second of silence, once</para>
			<para>WaitForSilence(300,3,10) will wait for 300ms silence, 3 times, and returns after 10 sec, even if silence
			is not detected</para>

			<para>If you set the <variable>PARKINGEXTEN</variable> variable to a

			the following variables can be used to dynamically create new parking lots.</para>
			<para>If you set the <variable>PARKINGDYNAMIC</variable> variable and this parking lot

			<note>
				<para>This application must be used as the first extension priority
				to be recognized as a parking access extension.  DTMF transfers
				and some channel drivers need this distinction to operate properly.
				The parking access extension in this case is treated like a dialplan
				hint.</para>

			<note>
				<para>Parking lots automatically create and manage dialplan extensions in
				the parking lot context.  You do not need to explicitly use this
				application in your dialplan.  Instead, all you should do is include the
				parking lot context in your dialplan.</para>

			The advantages of not stripping out quoting, and not caring about the separator characters (comma and vertical bar)
