Helo.
The new problem has just appear.
After established logical connection I try send the data from file (G.711 bits
received during incomig call).
I made this function (in VS 2007):
SendDataB3Req(DWORD dwApplId,BYTE bPLCI, WORD wNCCI, WORD DataLength, WORD
DataNumber, char DataBuffor[1024+1])
{
CAPI_MSG CAPIMsg;
DWORD capi_error;
CString MSG;
CAPIMsg.header.appl_id = (WORD)dwApplId;
CAPIMsg.header.command = _DATA_B3_R;
CAPIMsg.header.number = 0;
CAPIMsg.header.controller = 1;
CAPIMsg.header.plci = bPLCI;
CAPIMsg.header.ncci = wNCCI;
CAPIMsg.header.length = (WORD)(sizeof(CAPIMsg.header)+10);
CAPIMsg.info.data_b3_req.Data=(DWORD)&DataBuffor; //DWORD
CAPIMsg.info.data_b3_req.Data_Length =DataLength;//DataLength; //WORD
CAPIMsg.info.data_b3_req.Flags=0; //WORD
CAPIMsg.info.data_b3_req.Number=DataNumber; //WORD
capi_error = CAPI_PUT_MESSAGE( dwApplId, &CAPIMsg );
}
During logigal connection apllication takes:
char *FileName = "received.dat";
FILE *plik = NULL;
plik = fopen(FileName,"r");
memset(&DataBuffor,0,1025);
fread(DataBuffor,sizeof(char),1024,plik);
for (int i=0;i<40;i++)
{
SendDataB3Req(dwApplId,bPLCI,wNCCI,1024,i,DataBuffor);
WaitForConfirmation(dwApplId);
}
In telephon a hear only some cyclical noises. No voice.
It is correct in pointer to the data area?
Meaby is something wrong in size of data?

You never read more than the first 1024 bytes. 1024 bytes
is about 1/8th second of audio, so cyclic noise would
be exactly what I expect to hear in that case.

Ok. I has changed this loop:
for (int i=0;i<40;i++)
{
fread(DataBuffor,sizeof(char),1024,plik);
SendDataB3Req(dwApplId,bPLCI,wNCCI,1024,i,DataBuffor);
WaitForConfirmation(dwApplId);
}
Still cyclic noise - 40 times...
During each loop application read 1024 times 8-bits words (summary - 1024
bytes - 1/sek voice). After that, the DATA_B3_REQ is being filled.
I dont know what could be wrong...

I *guess* your not using the Window mechanism at all.
As I today answered to your other posting, if you would provide a complete
CAPI trace, we coudl mor help you and give hints and woudl less have to
guess ;-)
Just a question: You do have the CAPI 2.0 4th Edition documents, dont you?

What does "Widndow mechanism" mean?

Ok. Sorry :-). I'll be better the nest time.

Marcin,

The Message Buffuer / Message Queue windowing meachanism. As I can see from
that litle excerpt from your code I *guess* you just "disabled" the queueing
mechanism by sening our an message and waiting for the confirmation before
sending the next; well at least I guess you do so, lokking at a trace it
woudl be obvious within seconds.

Well, why not THIS time, why bnot just prividing it now?!???
I think not only for me it isnt great fun spending time, trying to help if
the one who asks does give only few informations.

Fine! Thats the current one!
For my current guess whats going wrong, pls. read Part 2 e.g. Chapter
8.18.1.1
"The number of simultaneously available data blocks has a decisive effect
on the data throughput in the system and should be between 2 and 7. At least
two data
blocks must be specified."

Marcin,
also have a look at CAPI 2.0 Part 1, Anex A, A.2 Data Transfer.
The buffer windowing / queue mechanism is schwon there in a short flow
sample.

I found the problem.
In The "freadt function is bug. I used function dedicated to Visual Studio C++
for read & write data.
Thanks for help.
