Is the phone line VoIp? If yes well the answer is yes and no, since of course each device, has it's own IP address but they are linked to the same account, but this information is sensitive and detained by your service provider, and it cannot be disclosed unless in legal cases. But an attacker can get this information only by getting access to the service providers databases (kinda rare), but the thing I am not sure of is that the first two parts of the IP address are owned by the service provider, and thus an outside attacker will know these two IP adresses (e.g router and phone) are linked tonthe same SP(service provider), but I am not sure if the two ip's in the last two part have similar or consecutive IP's.
So anyone with precise knowledge please correct me, since I might be totally wrong.
