In the guts of our system, there is a single, big, red knob labeled “Call Volume.” (Metaphorically speaking, of course). When we started, we set it at a bit over 10,000 calls per hour, and that worked fine. But since more folks are using the system and want to run ever-larger campaigns, we decided to twist the knob to 30,000 - thus tripling our capacity. To do this, we had to add a bit more hardware first, but fortunately our system is built so we can just add more computers as we grow. Need to make even more calls? Just let us know, and we’ll crank the knob up even higher.
