Linksys SPA2102 and Digium card

I have a Linksys SPA2102 from a VoIP provider and 1 (one) telephone A connected to it.

I also have my own Asterisk server with a telephone B connected.
This server has a Digium card with 1 FXS and 1 FXO port. (which are not in use at the moment)

I want to get rid of the telephone A connected to the Linksys, so that I have one telephone less.

Q: Is it possible to connect the Linksys Phone1 port (where telephone A is connected) to the Digium card, so that I can route the calls to telephone B ?
