Can I install The Ultimatoll with my automatic two-line switching device?
If your device is capable of releasing the same amount of DC loop current originally available from each of your phone lines, it will work satisfactorily with all of The Ultimatoll Controllers. There is, however, no guarantee that this will always be the case with all of the two-line automatic switching devices available in the market. The afore mentioned condition is likely to be satisfied with devices not powered by the phone line.
