We are working to a big project and a we need to install 2 SPA8000 to reach an branch at 7 kilometers away. Is it possible to make a phone confersation at 7 kilometers by using SPA8000 and standart 24AVG cable ?
For the wire length much above 9000 feet,it is unknown. 9000 feet for in premise use is long enough. Off premise use is not recommended since there is no required protection circuit to prevent the damage.
