I need help on setting up a wfi station to brod cast over 40 acrers . Then I need a router that will handle 2 tel lines and conect them to my smart phone though the Internet . There is no cell reception here and dsl was just installed . I would pay someone to design a system but can't find anyone local to morganton nc

You aren't going to get a single station to broadcast tat large an area. You are going to have to have repeaters spaced strategically throughout the acreage. Who is your Internet provider? Many have a special division for businesses that can help design and setup a "campuswide" coverage.

Ok I can get that done . What about the router that will handle 2 line and transfer call to smart phones . Also I understand that somehow I can get my AT&T phone # to ring though the router wifi. I understand cisco does this and is used by some fire stations .

That is a whole other issue and beyond my knowledge.
