With small installations I use Asterisk to record calls on the same server. Larger installs I have worked on have utilised a separate call recording server.
Where would you suggest the line is drawn. In a small call centre environment, how many seats would consider to be enough to warrant a separate recordings server?
Obviously, the spec of the server would play a part, but lets say a reasonably spec’d SME type server few gig ram, raid5, decent cpu etc.
