answering calls

[David Wetzel]

hi folks,

I try to create a lib to wrap the i4b telephony stuff in a way that makes it easy to use from external 
programs. I do this as a first step to add i4b support to Asterisk.
I do not intent to run the isdnd.

Imagine there are N different ISDN cards in the system. Some may be Fritz with 2 channels some may 
have a PRI with 30 channels.

If I understand the documentation right, all signaling and accept/reject control is made via /dev/isdn 
and the real voice data will flow via /dev/isdntel*

On an incoming call, I get the stuct msg_connect_ind_t which contains controller and channel number.

The driver's int number I seem to get via lookup_l4_driver() from rc_config.c.

But how to get the driver_unit?
How do I know which /dev/isdntel* to use?

Can i4b find the right driver/unit based on the cdid?

Thanks!

dave
