The unanswered.xslt file is used for e-mail notification of unanswered or forwarded calls.
The XML files on which the template is used are created by the server. File sample_unanswered.xml contains example files for an unanswered call. File sample_redirected.xml contains example files for a forwarded call. The files are to be found in the templates/default directory.
You can use the msxlt.exe program supplied to apply an XSLT to an XML file. Open a command line in the installation directory:
msxsl.exe templates\default\sample_unanswered.xml templates\default\unanswered.xslt -o unanswered.htm
If the logLevel is set under Events on debug, a XML file is provided in the list logs for every unanswered phone call. You can use this for the development of your own XSL templates.
