Hello all, I have few questions about resources when there are multiple in / out calls going on in FS. 1. I use Cepstral. If I have 20 calls at the same time, does playing media (from FS) suffer performance issues due to Cepstral licensing. I just have 1 server Cepstral license. 2. There is no sound card on my server (Windows 2008 Standard). Does functioning of FS media modules / Cepstral suffer because of lack of sound card? If I install high quality sound device, is it going to make the voice quality better? 3. How do I make sure FS process has enough resources (processor / memory) when other taxing tasks are going on the server (e.g. backup)? I have noticed voice getting broken when someone calls when backup is going on. Thank you so much for guidance / help.
