I'm trying to setup CCX 7.0(1)SR5 silent monitoring using desktop monitoring. There are no error messages, but supervisor does not hear anything. I turned up debug on agent and supervisor desktops. Before I saw in agent.log message "WARN VOIP3004 Unsupported Codec. PayloadType = <G.729>". This is quite explanatory. I made sure that phones use G711 codec. Tested while in call ( double ? ) - it is G.711. Still the same - no sound. Now I see "improvement" in agent.log - "WARN VOIP3004 Unsupported Codec. PayloadType = <UNKNOWN>". CCX server is configured to use G711. Have anybody encountered something like this? Does it make difference for CAD - G711u or G.711a? Any guesses which codec is UNKNOWN?
