...w... Mostly taking care of the underlying systems. I've now reached the point where I'm being drawn more and more into the call processing side of things. My background is in computer and "classic" telephony systems (DMS250/MTX, DSC 400, T1, channel banks. telabs analog echo supressor modules and analog mux etc). I've seen one commercial product recently based on openh323proxy called a transit softswitch and now I'm looking at asterisk. Is there a difference between what asterisk is and a softswitch? Can someone explain it in small words and phrases for me? Thanks...
