Call is initiated by LCR:
If a call is received from LCR, a MESSAGE_NEWREF is received first.

+the received 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.
If a call is requested from Asterisk, a new chan_call instance is created.
The new Asterisk instance pointer (ast) is stored to chan_call structure.

+If the call is received (lcr_call) A MESSAGE_NEWREF is sent to LCR requesting
a new call reference (ref).
+The ref_was_assigned ist set to 1.
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.
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 ref_was_assigned==1 shows that there is no other ref to be assigned.
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.
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.
+The ref_was_assigned==0 shows that a ref is still requested.
Later, if the MESSAGE_NEWREF reply is received, a MESSAGE_RELEASE is sent to
LCR and the chan_call instance is destroyed.
