I use call forward. My home phone is Bell one and my cell phone is fido one. I dial *72 and my cell phone number at my home phone before I leave home, then, it's working to receive a call at my cell phone when others call my home phone. But you need pay cell phone fees or use your airtime. After I back home, dial *73, then, it's canceled forward.
I also can use my cell phone for forwarding function when I am at home. Find your cell phone forward function (as my phone, from "setting" -- "call setting" --" call forwarding", and so on, to your home or any other phone number). You can receive a call at that number transfered from your cell phone. But, it needs pay forward fees plus airtime.
I think there is a similar function as Bell phone has at your 网络电话(cik)
I hope it is useful for you.
