What is the best and least expensive way to transfer calls to a long distance number? I haven't been to site in a while but they either have 1 or 2 ds cards nothing fancy. I'm guessing this CICS is about 2.0 software. Also other than ds and ci what are the valid trunk cards? I know of the BRI card but have never had the opportunity in all my years to use one,if anybody can explain I'd appreciate it .
