Summary

With SwyxWare v4.0 it is possible to define own custom scripts with the Graphical Script Editor (GSE). To create scripts using the GSE you have to license the Option Pack - Extended Call Routing.

This articles describes, how to implement a simple Call logging into a text file.

Installation of the example rule

Download the complete example code usig the link at the end of this article and copy all included files into the c:\gse_demo To load the LogFile.rse file as rule into your Call Routing Manager i.e. Graphical Script Editor please follow these steps:

 

  • Open the Call Routing Manager.
  • Click the New... button.
  • Select Graphical Script Editor and click on Ok.
  • Within the GSE open the File | Import... menu.
  • Select the LogFile.rse. The rule will be imported and your GSE will look like this:

How it works

Custom code can only be added to the Start rule. All consts, variables and functions you'll define here are available all over the script, i.e. can be used in all blocks e.g. the Evaluate block. Please note, that the final script being created by the GSE places the VBScript statement option explicit to the top of the script. This forces all variables to be used within the script to be declared properly.

As you will see in this example a function will be defined within the custom code in the Start rule, which will later be used within a Set Variable block. This is a small trick: we don't need the new defined variable, we use it just to call our function.

The function InsertCallIntoFile opens a text file and appends the caller id together with the current date and time to it. This is how the code looks like:

 

  1. ' FileOpen iomode Values
  2. Const fsoForReading = 1
  3. Const fsoForWriting = 2
  4. Const fsoForAppending = 8
  5.  
  6. Const fsoCreateIfNotExist = True
  7.  
  8. Function InsertCallIntoFile(ByVal callerID)
  9.  
  10.     Const filename = "c:\gse_demo\test.txt"
  11.  
  12.     Dim fso
  13.     Dim file
  14.  
  15.     ' Create FileSystemObejct
  16.     fso = CreateObject("Scripting.FileSystemObject")
  17.  
  18.     ' Open text file
  19.     file = fso.OpenTextFile(filename, _
  20.       fsoForAppending, fsoCreateIfNotExist)
  21.  
  22.     ' Write (append) CallerID into file
  23.     file.WriteLine("""" & callerID & """,""" & _
  24.       CStr(now) & """")
  25.  
  26.     file.Close()
  27.  
  28.     file = Nothing
  29.     fso = Nothing
  30.  
  31. End Function

After activating this rule all incoming calls with be recorded within the text file. Note that we exit the script using the Rule skipped block. This will enable us to use other rules after this one within our call routing.

Notes

 

  • All callrouting scripts, and therefore also your code, runs under the SwyxWare Service Account. Please make sure that this account has the needed priviliges to access the file/database.

  • The script in this example does contain no Error Handling. If an error occurs at runtime, e.g. when trying to access a database, this error will not be handled, the script will stop and the call get lost. If you have enabled Server Tracing for SvrScript on level Info3 you will find the original Microsoft Script Engine error message within the server trace file.

    To get your own error handling you have to disable the standard error handling by the Script Engine:

     

    1. On Error Resume Next

     

    Place this line of code at the beginning of your function. Now you have to check for error at every potential place and do your own error handling:

     

    1. ' Open connection to Database
    2. db.Open sDsn
    3. If Err <> 0 then
    4.     'do something, e.g.:
    5.     FunctionName = False
    6.     Exit Function
    7. End If
