Hi

Can anybody explain to me, what contains Additional Info
in CONNECT_IND?

When two B channels are busy (voice connections alredy
exist) and coming third call, the Additional Info struct
in CONNECT_IND contains the following data:

07 02 02 the rest are zero

I can't understand what kind of information contains
this struct.

regards
Pawel
P.S.
I have BRI ISDN (Aethra NT1 PLUS) with 2 phones connected
to TA, and ISDN FRITZ!PCI card connected to S bus.

Hi Pawel

07 - length of additional info struct
02 - length of B channel info struct
0200 - channel use - here 2 : use neither b channel nor d channel
00 - empty key pad struct
00 - empty user user struct
00 - empty facility struct
00 - empty sending complete struct

More info: capi doc part 1 chapter 6.1 [4th ed. p77f]

Why your capi implementation thinks you want to know that additional
information, I don't know. I guess it is just polite ;)

Bye
Michael

My simple caller ID application must notice user (and write in raport
file), that somebody try connect when all phone lines (B channels) are busy.
