I just bought Voipbusterpro (15 Euro) today. I made two phone calls to my parents in China. The phone calls are 0.039 Euro(connection)+0.01(Euro/minute). My parent's phone is a landline phone and the the landline phone also connects to 小靈通. The basic of my parent's phone is when the incoming phone rings, you may pick either landline phone or 小靈通, in that way they are connected.
My question is: by having 小靈通 connected to the landline, even though you only pick landline, still the phone is considered to be mobile phone?
Thanks for your help.
