Hi everyone,

I am writing a CAPI program that dials a number and plays a sound file
when the receiver pick up the call. I used an ordinary fax machine as
the receiver.
However, I found out that even before I pick up the call on the fax
machine, my program receives connect_b3_active_ind . Why is that ? As a
result of this, the sound file finished before I pick up the call
(unless I pick it up quickly). How can I prevent this ? How can I
detect the pickup event (or the real connect event ) ?
Thanks everyone.

Regards,
Kelvin

Our company oracle has taken a day off, so in absence of any useful
information in your post I have to rely on guessing... Please try to make
a habit of posting a CAPI message flow when you're encountering problems.
(Hint: google for ISDN WebDecoder to make such a message flow readable for
everyone.)

As you're establishing an outgoing call, you receive a
CONNECT_B3_ACTIVE_IND because you asked CAPI to establish a Layer 3
connection by posting a CONNECT_B3_REQ, didn't you? Do you have the "Early
B3"-bit set in your Listen Mask? (Even if it's not enabled it's debatable
whether a CONNECT_B3_REQ before a CONNECT_ACTIVE_IND shouldn't enable
Early B3 for the current call anyway. I think it should.)

Or, by chance, did you set up DCE mode?

A CONNECT_ACTIVE_IND indicates that the remote party has picked up the
call. Don't try to establish a Layer 3 connection before that.

Hi Danilo,

Thanks for your answer. Here is the start of the message flow:
I just don't know why I receive the connect_b3_active_ind or
connect_ind before
I pickup the phone from the fax machine.
Can you see why from the trace ?
Thanks!

Hi,

Our company oracle has taken a day off, so in absence of any useful
information in your post I have to rely on guessing... Please try to make
a habit of posting a CAPI message flow when you're encountering problems.
(Hint: google for ISDN WebDecoder to make such a message flow readable for
everyone.)
As you're establishing an outgoing call, you receive a
CONNECT_B3_ACTIVE_IND because you asked CAPI to establish a Layer 3
connection by posting a CONNECT_B3_REQ, didn't you? Do you have the "Early
B3"-bit set in your Listen Mask? (Even if it's not enabled it's debatable
whether a CONNECT_B3_REQ before a CONNECT_ACTIVE_IND shouldn't enable
Early B3 for the current call anyway. I think it should.)
Or, by chance, did you set up DCE mode?

A CONNECT_ACTIVE_IND indicates that the remote party has picked up the
call. Don't try to establish a Layer 3 connection before that.
Regards,
Danilo Kempf

Hi there,

could it be, that the fax-machine already accepts the call before you pick
up the receiver?

Your call-flow looks totally ok, you are getting a connect_active_ind upon
which you
establish the connection... so I guess the destination is the problem - have
you tried it
with a different destination-number (your mobile phone for example)

Best regards,
Tobias

Hi Danilo,
I just don't know why I receive the connect_b3_active_ind or
connect_ind before
I pickup the phone from the fax machine.
Can you see why from the trace ?
Thanks!

Hi,

Our company oracle has taken a day off, so in absence of any useful
information in your post I have to rely on guessing... Please try to make
a habit of posting a CAPI message flow when you're encountering problems.
(Hint: google for ISDN WebDecoder to make such a message flow readable for
everyone.)
As you're establishing an outgoing call, you receive a
CONNECT_B3_ACTIVE_IND because you asked CAPI to establish a Layer 3
connection by posting a CONNECT_B3_REQ, didn't you? Do you have the "Early
B3"-bit set in your Listen Mask? (Even if it's not enabled it's debatable
whether a CONNECT_B3_REQ before a CONNECT_ACTIVE_IND shouldn't enable
Early B3 for the current call anyway. I think it should.)
Or, by chance, did you set up DCE mode?

A CONNECT_ACTIVE_IND indicates that the remote party has picked up the
call. Don't try to establish a Layer 3 connection before that.
Regards,
Danilo Kempf

Hi,
The fax machine is set to non auto answer. So it won't be able to
accept the call.
If I pickup the call quickly, I able able to hear the later part of the
voice file.
The fax machine and the fax card are connected by a small PBX.
Also the card is an Eicon analog card.
Would it be related to analog ?

Post by Tobias Erichsen
Hi there,
could it be, that the fax-machine already accepts the call before you pick
up the receiver?
Your call-flow looks totally ok, you are getting a connect_active_ind upon
which you
establish the connection... so I guess the destination is the problem - have
you tried it
with a different destination-number (your mobile phone for example)
Best regards,
Tobias
