Hi Janine,
In CS 3.6.x and CVP VXML Server 4.0, users no longer need to edit web.xml to enable VoiceXML debug logging. Instead, a debug logger should be configured. For instructions on how to do this on the Call Services side, please refer to the following KB article:
"
How to enable VoiceXML debug mode on Audium Call Services 3.6"
Note that you can configure loggers in Studio as well, so you could follow similar steps on the Studio side (from within the project properties dialog).
In regards to a code sample for logger development, this is something we recognize would be helpful. We will keep this in mind when we update our sample code section, thanks for the feedback.
Regards,
Vance
