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
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)



Call Transfer and 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



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