Detailed description of Class of Service

Last Updated : Oct 30, 2012 |

Use the COS feature to allow or deny user access to some system features, such as:

  • Automatic Callback

  • Call Forwarding

  • Data Privacy

  • Trunk-to-Trunk Transfer Override

  • QSIG Call Offer Originations

  • Contact Closure Activation

  • Console Permission

Use the Class of Restriction (COR) feature, instead of COS, to define the restrictions that apply when a user places or receives a call. For more information, see the Class of Restriction feature.

COS does not apply to trunk groups, except for the Remote Access feature. For more information, see the Remote Access feature.
