The correct product to replace the CS 3.0 is most likely the SR-3. It does everything that the Comswitch CS 3.0 does except notify you have a call waiting call. Unlike the Comswitch CS 3.0, the SR-3 is 100% accurate so you should not need this feature. Since the SR-3 is a different technology it learns the voltages of your local phone company distinctive ring service so it can't ever make a mistake.

Your voice calls always go to the voice, fax calls always go to your fax and your alternative calls on the second distinctive number always go to the assigned device. There should be no need to manually transfer any calls. Since the SR-3 is 100% accurate, we didn't include this feature because frankly unless the unit malfunctions you don't need it.

We also have the Versa-Link ATX-250 automatic or distinctive ring 2 device fax switch which will also do the manual transfer from your phone if you require it.

The superior replacement for the CS 3.0 for distinctive ring is the SR-3. Since it is 100% accurate, has surge and lightening protection as well as all parts in the manufacturing are specified for a minimum of 40 years, which the Command product never had. We are thoroughly confident that you will much happier with it. It shouldn't wear out. 40 years is a long time. I have personally used the SR-3 for my voice and fax. For me, it has been 100% accurate and perfect for more that 25 years. Perfection is hard to beat.

The SR-3 is simpler than the CS 3.0. It does only one thing. It routes the calls from the distinctive ring to the appropriate device and never makes mistakes. To repeat, it is 100% accurate.

Instead of having two or three phone lines, it allows you to have only one phone line with distinctive ring (you only pay for one phone line plus the distinctive ring option instead of paying for three lines which obviously almost cost you 3 times as much) for virtually the same functionality.

Basically it works the same as having two or three lines except you can't use them at the same time.
