Hello There, I have the following stuff

A Lenovo T60 (with a ethernet and telephone port separately)

A 3G Modem with a SIM Card Inside, hardware unlocked to take and receive calls (Huawei Mobile Partner)

A Table Phone (Don’t know weather it has those VoIP or other fancy features)

I usually use the (Huawei Mobile Partner), to send and receive calls from my SIM Card, through the Modem. I there any way to just receive the call to the Table Phone through the Modem. (Its just like rerouting audio from the modem to the telephone).

Sorry if posting on an irrelevant sub reddit
