There is no easy answer. Here are four scenarios. Mix, match & guess.
- One Server has run three dialers each pushing 300 calls at the same time
- One Server has handled 20 small call centers of 5-20 users with mix batches of call recordings.
- One physical server will support 70 concurrent calls, with full call recording and the data base being thrashed by supervisors.
- One large call center can be scaled to 600 agents if the queues, call recordings and statistics are given dedicated resource.
