Preparing to administer Emergency Calls from Unnamed IP Endpoints

Last Updated : Oct 07, 2020 |

Procedure

  1. On the Optional Features screen, ensure that the G3 Version field is set to V13 or later.

    V13 is the version for Communication Manager Release 3.0. If this field is not set to V13 or later, your system does not support the Feature Description and Implementation feature. Go to the Avaya Support website at http://support.avaya.com for current documentation and knowledge articles related to administering Emergency Calls from Unnamed IP Endpoints, or to open a service request.

    To view the Optional Features screen, type display system-parameters customer-options. Press Enter.

  2. The Emergency Calls from Unnamed IP Endpoints feature requires that the TTI for voice terminals option be turned on.

    Your license file sets this field. If the TTI for voice terminals option is turned off for your system, IP telephones that are in the TTI state are unregistered.

    To verify if the TTI for voice terminals option is turned on:

    1. Type display system-parameters features. Press Enter.

      The system displays the Feature-Related System Parameters screen.

    2. Press Next until you see the TTI/PSA Parameters section.
    3. Ensure that the Terminal Translation Initialization (TTI) Enabled? field is set to y.
    4. Ensure that the TTI State field is set to voice.
    5. Press Enter.
      Important:

      Administrators or technicians might often turn off TTI during software upgrades. Remember that you must turn TTI back on when the upgrade is complete.

      Security alert:

      You might choose to leave TTI turned off for security reasons. If you want to use the feature but not use TTI, set the TTI FAC field on the Feature Access Code (FAC) screen to blank.
