-How does it work:
+Registering to LCR:
-To connect, open a socket and send a MESSAGE_HELLO to admin socket with
+To connect, open an LCR socket and send a MESSAGE_HELLO to socket with
the application name. This name is unique an can be used for routing calls.
+Now the channel driver is linked to LCR and can receive and make calls.
-To make a call, send a MESSAGE_NEWREF and a new reference is received.
-When receiving a call, a new reference is received.
-The reference is received with MESSAGE_NEWREF.
-Make a MESSAGE_SETUP or receive a MESSAGE_SETUP with the reference.
+Call is initiated by LCR:
-To release call and reference, send or receive MESSAGE_RELEASE.
-From that point on, the ref is not valid, so no other message may be sent
-with that reference.
+If a call is received from LCR, a MESSAGE_NEWREF is received first.
+A new chan_call instance is created. The call reference (ref) is given by
+MESSAGE_NEWREF. The state is CHAN_LCR_STATE_IN_PREPARE.
+After receiving MESSAGE_SETUP from LCR, the ast_channel instance is created
+using ast_channel_alloc(1). The setup information is given to asterisk.
+The new Asterisk instance pointer (ast) is stored to chan_call structure.
+The state changes to CHAN_LCR_STATE_IN_SETUP.
+
+
+Call is initiated by Asterisk:
+
+If a call is reveiced from Asterisk, a new chan_call instance is created.
+The new Asterisk instance pointer (ast) is stored to chan_call structure.
+A MESSASGE_NEWREF is sent to LCR requesting a new call reference (ref).
+The current call ref is set to 0, the state is CHAN_LCR_STATE_OUT_PREPARE.
+Further dialing information is queued.
+After the new callref is received by special MESSAGE_NEWREF reply, new ref
+is stored in the chan_call structure.
+The setup information is sent to LCR using MESSAGE_SETUP.
+The state changes to CHAN_LCR_STATE_OUT_SETUP.
+
+
+Call is in process:
+
+During call process, messages are received and sent.
+The state changes accordingly.
+Any message is allowed to be sent to LCR at any time except MESSAGE_RELEASE.
+If a MESSAGE_OVERLAP is received, further dialing is required.
+Queued dialing information, if any, is sent to LCR using MESSAGE_DIALING.
+In this case, the state changes to CHAN_LCR_STATE_OUT_DIALING.
+
+
+Call is released by LCR:
+
+A MESSAGE_RELEASE is received with the call reference (ref) to be released.
+The current ref is set to 0, to indicate released reference.
+The state changes to CHAN_LCR_STATE_RELEASE.
+ast_queue_hangup() is called, if asterisk instance (ast) exists, if not,
+the chan_call instance is destroyed.
+After lcr_hangup() is called-back by Asterisk, the chan_call instance
+is destroyed, because the current ref is set to 0 and the state equals
+CHAN_LCR_STATE_RELEASE.
+If the ref is 0 and the state is not CHAN_LCR_STATE_RELEASE, see the proceedure
+"Call is released by Asterisk".
+
+
+Call is released by Asterisk:
+
+lcr_hangup() is called-back by Asterisk. If the call reference (ref) is set,
+a MESSAGE_RELEASE is sent to LCR and the chan_call instance is destroyed.
+If the ref is 0 and the state is not CHAN_LCR_STATE_RELEASE, the new state is
+set to CHAN_LCR_STATE_RELEASE.
+Later, if the MESSAGE_NEWREF reply is received, a MESSAGE_RELEASE is sent to
+LCR and the chan_call instance is destroyed.
+If the ref is 0 and the state is CHAN_LCR_STATE_RELEASE, see the proceedure
+"Call is released by LCR".
