no CONNECT_B3_IND

[Marcin p.]

Hi.

Helo. I'am student of Technical University of Lodz in Poland. I have to
write the program (something laike SoftPhone) using the CAPI2.0 standard (Eicon
library).The connection is established between two controllers (Fritz!CARD-USB &
Fritz!X-USB).Incomming call and received data looks fine (from ISDN-telephon to
PC), but outgoing call deosn't work. I cannot receive CONNECT_B3_ACTIVE_IND? The
queue is empty?On the second side the application received DATA_B3_IND, despite
the fact the firs side dont send the DATA_B3_REQ. (no logical connection - no
CONNECT_B3_ACTIVE_IND).Do you have any idea?Martin

A CAPI-Trace might help tracking down the problem. You didn't
say what operating system you're using but for Windows there
is a Debug-DLL provided by AVM that creates a text-file containing
all CAPI-message that were sent to/received by the hardware.

I'm using Visual Studio
OS - Windows XP SP2


Below is the effect of my application:

[OK ] CAPI_REGISTER Application ID = 2
[OK ] CAPI_PUT_MESSAGE: CONNECT_REQ:
CIP Value: 4
Called Party Number(4): 1101
Calling Party Number(4): 1102
Called Party Subaddress(0):

....

ApplId=2 CapiError: 0
[OK ] CAPI_GET_MESSAGE: CONNECT_ACTIVE_I Received(0x8203)

[OK ] CAPI_PUT_MESSAGE: CONNECT_ACTIVE_RESP
[OK ] CAPI_PUT_MESSAGE: CONNECT_B3_REQ:

[OK ] RECEIVED CONNECT_B3_CONF: OK. Connect B3 is active PLCI=1, NCCI=1,

...
ApplId=2 CapiError: 0
[OK ] CAPI_GET_MESSAGE: DISCONNECT_B3_I Received(0x8284)

ApplId=2 CapiError: 0
[OK ] CAPI_GET_MESSAGE: DISCONNECT_I Received(0x8204)
[OK ] CAPI_RELEASE ApplId = 2 released successfuly.

After CONNECT_B3_CONF I dont receive CONNECT_B3_ACTIVE_IND. The QUEUE is empty
when a I try get the some message (CapiError = 0x1104);
I'll try use CAPI_Trace.

Thanks.

What values do you use for registration?
What B-protocol-settings are used?

You can get around repetitive calls of CAPI_GET_MESSAGE
by calling CAPI_WAIT_FOR_SIGNAL that returns if a message
is available to be read from the queue.

This is a different number than you called. Is that supposed
to happen?

What B3-Protocol do you use? If it's a protocol like X.25 you need
to specify NCPI-values (not ncpi). As well, the PLCI-value 1 looks
wrong (it's a combined value of the physical line value and the
number of the controller, so 1 is definetely too low).

If 0x8284 is the diconnect-reason, I never saw that before. You might
check the documentation of your CAPI-driver what that error means.

... should be read as (not ncci), I always write the one instead of
the other.

Thanks for all.

I found the error (using CAPI-Trace). I wrong fill the struct in CONNECT_REQ
(exactly B Protocol (B1, B2, B3)- default, instead of 0x01 for B1, B2, B3). Now
I can receive the CONNECT_B3_ACTIVE_IND, and the logical connection is
established :-)

The next step is sending the data between terminals.
At first I would try to send the G.711 bits from my application (from file) to
ISDN-telephon. I have some little problems with fill the DATA_B3_REQ.


Thanks one again for help.

Marcin,

if you gave us a *complete* CAPI Trace, we might could help you more. ;-)
