My situation is this. We are currently subscribing to over 60 analog 4-wire leased lines to different remote sites from our central office. The analog leased lines are used to carry audio traffic from central office's controller to remote sites' analog 4-wire transmitter. Both the controller and transmitter are equipped with analog interface port for the 4-wire leased line.
We have been given 6 months to move away from the analog leased line by the service provider. We are in a dilemma now as all the options that we can think of are too costly.
I was having the idea of replacing the analog leased lines with POTS lines, assuming it can be done. This would be the most cost effective as I can get a low monthly fixed rate for the POTS line.
Does any have a suggestion how I can do this?
Any ideas are most welcome.
