New Data protocol messages

CDC_STATE <br\> CDC_CMD <br\> CDC_CMD could be changed with COMMAND_RESPONCE?


Startup sequence

The WCSD software is defined as device number 198. When amcd receives a RESET_TAKEN message from device 198 it configure itself for billing.

AMCD                                                        WSCD
                                  <----                    RESET_TAKEN(0)
(AMCD remember the WCSD address, also AlphaNet use)
COMMAND_RESPONCE (responce code)  ---->
  (1 = Licence OK or 4 = not allowed)

Digit Collection

Example 1:<br\> System setup: <br\> AudioCodes SIP gateway, trunk line 1 programmed with number 0047. <br\> 0047 programmed in AlphaCom as feature 83 global number with flag for Call Detail Control.<br\>

WCSD programmed with pin code "12" for user "101" <br\>

User "101" dials trunk extension "0047" then local number 64871300

AMCD                                                        WSCD
CDC_STATE (START,       REF, 101, 0047) ----->             (Starts new billing process)
CDC_STATE (PIN_DIGIT,   REF, 101,    1) ----->             (Verify pin digits)
CDC_STATE (PIN_DIGIT,   REF, 101,    2) ----->
                                        <-----              CDC_CMD (REF, OK)   (Pin OK)
   (Send INVITE to SIP GW, SIP-trunk dial tone)
...
CDC_STATE (ESTABLISHED, REF, 101, 0047) ----->             (Sip connection established) 
CDC_STATE (TRUNK_DIGIT, REF, 101,    6) ----->             (Collect digits for billing information)
CDC_STATE (TRUNK_DIGIT, REF, 101,    4) ----->             
 digits....871300                                          (When user stops dialing start billing?)
....
CDC_STATE (ACTIVE,      REF, 101, 0047) ----->             (Received every 10 sec as a heartbeat)
.....
CDC_STATE (DISCONNECT,  REF, 101, 0047) ----->             (Conversation disconnected)


When the link to the SIP gateway is established AlphaCom has now knowledge if the user reach a destination or not.

Example 2:<br\> System setup: <br\> SIP call manager <br\> 0047 programmed in AlphaCom as feature 81 Area code with flag for Call Detail Control and digit collection.<br\>

WCSD programmed with pin code "12" for user "101" <br\>

User "101" dials trunk extension "0047"

AMCD                                                        WSCD
CDC_STATE (START,       REF, 101, 0047) ----->             (Starts new billing process)
CDC_STATE (PIN_DIGIT,   REF, 101,    1) ----->             (Verify pin digits)
CDC_STATE (PIN_DIGIT,   REF, 101,    2) ----->
(New dial tone from AMC)                <-----              CDC_CMD (REF, OK)   (Pin OK)
CDC_STATE (TRUNK_DIGIT, REF, 101,    6) ----->             (Collect digits for billing information)
CDC_STATE (TRUNK_DIGIT, REF, 101,    4) ----->             
 digits..871300...                                         (When user stops dialing start billing?)
....
(User stops dialing or press M. SIP INVITE is sent with all collected digits 64871300)
...
CDC_STATE (ESTABLISHED, REF, 101,64871300) ----->          (Sip connection established) 
....
CDC_STATE (ACTIVE,      REF, 101,64871300) ----->          (Received every 10 sec as a heartbeat)
.....
CDC_STATE (DISCONNECT,  REF, 101,64871300) ----->          (Conversation disconnected)


Dependent on the call manager the ESTABLISHED message can arrive during ringing or when the B-side actually lifting the handset.

Failure situations

Illegal pin code

   (User get failure tone and disconnect)
