CDC STATE

Related to ABSD_Billing

CDC_STATE		0x009E	158	AMC 10.40
Message used for billing control, from AMCD to ABSD CDC = Call Detail Control. Response is CDC_CMD.
1	UINT2	Connection Reference for this "dialing" sequence (actually ST_IND of A-station)
2	NET_OBJ_REF	A-station (billed station), in NRF_LOCAL_DIRNO format.
3	UINT1	State of billing sequence. 1 START, user has initiated a feature requiring CDC (5 = feature dirno) 2 DIGIT, user has dial a digit (5 = digit netref) 3 ESTABLISHED, (SIP)connection established (200 OK received) 4 ACTIVE, call is still active, will come every 10 second during connection 5 DISCONNECT, CDC sequence ended, ABSD to release call. 6 SPEECH_START, Speech detected by AudioCodes 7 SPEECH_END, Speech detect end by AudioCodes
4	NET_OBJ_REF	Netref related to state type, (Feature, B-station or digit)

Modifications to the CDC_STATE Event

For the Billing system to be able to carry out the transfer of the A extension to a new A extension; the CDC_STATE event sent from AMC to ABSD needs to handle the new A extensions Connection Reference (UINT2) and Directory Number (NET_OBJ_REF).

Propose to add two new Sub Events in parameter #3;

• 8 CHANGE_A_IDENTITY
• 9 ACTIVE_SYNC

The new CDC_STATE event will look like this:

CDC_STATE		0x009E	158	AMC 10.40
Message used for billing control, from AMCD to ABSD <br\> CDC = Call Detail Control. Response is CDC_CMD.
1	UINT2	Connection Reference for this "dialing" sequence (actually ST_IND of A-station)
2	NET_OBJ_REF	A-station (billed station), in NRF_LOCAL_DIRNO format.
3	UINT1	State of billing sequence. 1 START, user has initiated a feature requiring CDC (5 = feature dirno) 2 DIGIT, user has dial a digit (5 = digit netref) 3 ESTABLISHED, (SIP)connection established (200 OK received) 4 ACTIVE, call is still active, will come every 10 second during connection 5 DISCONNECT, CDC sequence ended, ABSD to release call. 6 SPEECH_START, Speech detected by AudioCodes 7 SPEECH_END, Speech detect end by AudioCodes 8 CHANGE_A_IDENTITY, Change A extension, continue Billing sequence, AMCD must send ACTIVE_SYNC from new A extension within 3 seconds 9 ACTIVE_SYNC, first message/event from new A extension after CHANGE_A_IDENTITY, synchronize AMCD and ABSD with new message header
4	NET_OBJ_REF	Netref related to state type, (Feature, B-station or digit)

If the CDC_STATE is sent with CHANGE_A_IDENTITY; the parameter #2 will hold the new Directory Number
