New Data protocol messages
CDC_STATE <br\> CDC_CMD 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 (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
