The Skype for Business SDN Interface includes a utility named SIPObfuscator.exe for use by authorized partners that you can use to obtain the obfuscated value of a user name. The resultant obfuscated name can be used to query for dialog data involving the specified user when privacy protection is turned on. SipObfuscator.exe requires that .NET Framework 4.5 be installed.

SIP Obfuscator

When privacy protection is turned on in the SDN Manager, personal identifiable information in Skype for Business call and quality data is obfuscated by replacing identifying information with a SIP alias. For example, the SIP Uri of sip:adama@contoso.com might be replaced by sip:CE6AF05C9705A05E@contoso.com. When the network traffic patterns of a single user is specified, the SIP Obfuscator utility allows you to determine the obfuscated user's identity.

SIP Obfuscator is a Windows console application that is installed along with installations of the SDN Manager and Dialog Listener.

To use SIP Obfuscator, do the following:

  1. Select a known user name, for example, adama.

  2. Type the following command in a Windows console and press Enter.

SIPObfuscator adama

  1. The obfuscated user name is displayed as output, for example:

CE6AF05C9705A05E

To search for the data records associated with this user (sip:adama@contoso.com), you can search for the records containing sip:CE6AF05C9705A05E@contoso.com. An example of such an obfuscated data record is shown as follows:


<Start Type="audio">
    <From>
      <Id>87c1bcf104</Id>
      <EPId>1579d442a7</EPId>
      <URI>sip:CE6AF05C9705A05E@contoso.com</URI>
      ……
    </From>
</Start>
