Could you please guide me how to configure the TE120P card to use both voice and data?
Does nobody know or we could not do that?

These Digium cards are capable of doing this: TE12XP, TE2XXP, and TE4XXP(all Digium’s digital cards except the BRI card).
Here is a rough document on the process to do so:
