switts.mute_wcr

Replaces confidential data in whole-call recordings with silence.

Value	Boolean DEFAULT: (none)
How to set	In a VoiceXML application, using a <property> element. Set in the browser, using the Vendor-Specific-Parameters header in a SPEAK method.
Usage	Frequently used to protect confidential data.

You can set this parameter with either session or recognition scope: the setting is valid only for the next session or recognition, according to the level where it is set.

This parameter provides security for confidential data such as social security numbers or passwords that users might provide to applications. When true, it suppresses this information from any audio waveforms that might otherwise be saved.

Note: The switts.mute_wcr parameter suppresses this information for the application only. To suppress the caller's side of the conversation, use the swirec.mute_wcr parameter.

See Security levels to protect confidential data for an overview of how the switts.mute_wcr, switts.secure_context, and wcr_encrypt parameters interact with each other.

Sample definition in a VoiceXML application:

<field name="field2"/>

  <prompt>please say password</prompt>

  <property name="switts.mute_wcr" value="1"/> //muting is ON

  <grammar> ... </grammar>

</field>

The browser interprets the application definition in a SPEAK or SET–PARAM method:

Vendor-Specific-Parameters: switts.mute_wcr=1
