<para>Used to park yourself (typically in combination with a supervised

|
transfer to know the parking space). This application is always
|
|
registered internally and does not need to be explicitly added
|
|
into the dialplan, although you should include the <literal>parkedcalls</literal>
|
|
context (or the context specified in <filename>features.conf</filename>).</para>
|
|
<para>If you set the <variable>PARKINGEXTEN</variable> variable to an extension in your

|
parking context, Park() will park the call on that extension, unless
|
|
it already exists. In that case, execution will continue at next priority.</para>

CDR's, if they still exist, so as not to mess up

issues in future bridges;

|
|
|
Here are the rules of the game:
|
|
1. The chan and peer channel pointers will not change
|
|
during the life of the bridge.
|
|
2. But, in transfers, the channel names will change.
|
|
between the time the bridge is started, and the
|
|
time the channel ends.
|
|
Usually, when a channel changes names, it will
|
|
also change CDR pointers.
|
|
3. Usually, only one of the two channels (chan or peer)
|
|
will change names.
|
|
4. Usually, if a channel changes names during a bridge,
|
|
it is because of a transfer. Usually, in these situations,
|
|
it is normal to see 2 bridges running simultaneously, and
|
|
it is not unusual to see the two channels that change
|
|
swapped between bridges.
|
|
5. After a bridge occurs, we have 2 or 3 channels' CDRs
|
|
to attend to; if the chan or peer changed names,
|
|
we have the before and after attached CDR's.
|
|
6. Parking has to be accounted for in the code:
|
|
a. Parking will cause ast_bridge_call to return
|
|
either AST_PBX_NO_HANGUP_PEER or AST_PBX_NO_HANGUP_PEER_PARKED;
|
|
in the latter case, peer is (most likely) a bad
|
|
pointer, you can no longer deref it. If it does still
|
|
exist, it is under another's thread control, and
|
|
could be destroyed at any time.
|
|
b. The same applies to AST_PBX_KEEPALIVE, in which
|
|
case, the chan ptr cannot be used, as another thread
|
|
owns it and may have destroyed the channel.
|
|
c. In the former case, you need to check peer to see if it
|
|
still exists before you deref it, and obtain a lock.
|
|
d. In neither case should you do an ast_hangup(peer).
|
|
e. Do not overwrite the result code from ast_bridge_call.
