Can Asterisk inform me for a second incoming call of PSTN?

Hello guys. I have SPA-3102 with a PSTN line in FXO port. The SPA-3102 is connected with an Asterisk server. My question is what can i do when i speak to a line and a second call is coming? What are the possibilities i have ?
I’ve activated the Call Waiting feature of my landline provider but the asterisk(or the SPA-3102) doesn’t seem to understand that an incoming call has come, so to inform me… How is this possible ?

Thank you!
