Witness Viewer slow and unresponsive Witness Viewer slow and unresponsive camalone (TechnicalUser) (OP) 7 Aug 09 16:30 The Viewer starts normally and the Last 10 Calls By Extension query runs normally but, when I attempt to Retrieve Calls ... the browser becomes slow and, ultimately, unreposnsive. Any ideas? RE: Witness Viewer slow and unresponsive jgt93 (TechnicalUser) 2 Sep 09 17:34 Is this from a workstation? Is this performance the same from the server? RE: Witness Viewer slow and unresponsive camalone (TechnicalUser) (OP) 3 Sep 09 08:37 jgt93,Thanks for the reply. Typically, the Viewer is only run from a client workstation since it requires speakers (or headphones) to listen to the call recordings.Since I posted my original inquiry, we've isolated the problem to Symantec Client Firewall. Nothing is wrong with the firewall itself but, when we added the recorder server IP address to the firewall trusted zone, the Viewer runs normally.
