TAPI: LINE IDENTIFIER CHANGE WHEN NEW LINE IS ADDED ...

[diembi]

Hello,
I'm developing a TAPI client. I need make a call through a line. The identifier of this line change when a new line is added in server: example:

(time)
LineID Comment
---------------------
1 Modem 1
2 Modem 2 (this is the line i need use)
3 Network card

(time + 1)
LineID Comment
---------------------
1 Modem 3
2 Modem 1
3 Modem 2 (this is the line i need use)
4 Network card

Is possible identifier the line with a non-variable value??
Can I openLine with that non-variable value?

Thanks
