I am currently in the process of construction of a new home. So the wife and I have been discussing the need for old copper wire telephone jacks. There are currently planned to be 2 jacks in the house. We have in the past had our cable provider supply us with a voice line. This ultimately requires that our phone line be located close to a cable outlet. We both find this idea a little old style thinking and are looking for a new solution that uses modern technology.
There is also the added benefit of expanding to a second phone line for business purposes. This looks to be something much more easily done if all I would need to do is get and SIP trunk service along side a residential line.
