You must instruct Avaya Workplace Client users on mobile/cellular devices to use the device's native dialer application when connecting from a remote location. Doing otherwise associates the emergency call with the IP Office location rather than the mobile/cellular device user's true location.

Using Cellular Direct Numbers for Emergency Calls

For Avaya Workplace Client users on mobile iOS/Android devices, you can configure a set of "cellular direct numbers" (CDN).

When an Avaya Workplace Client user dials a cellular direct number, the client prompts the user to allow the device's native dialer to make the call using the mobile/cellular public telephone network. The call location information is then determined by the mobile/cellular network provider services.

The SET_CDNL Source Number

For IP Office R11.1 FP2 SP2 and higher, you can use the NoUser source number SET_CDNL= to add cellular direct number settings to the IP Office system configuration. These settings add CDN commands to the auto-generated 46xxsettings.txt file.

• SET_CDNL=DISABLED

  This adds the following string to the auto-generated 46xxsettings.txt file. This disables cellular direct number operation.

  • SET CELLULAR_DIRECT_NUMBER_LIST DISABLED

• SET_CDNL="911","9911"

  This adds the following strings to the auto-generated 46xxsettings.txt file. These enable cellular direct number operation and specify the numbers that will trigger the feature. Enclose each number in " " quotation marks. Separate multiple numbers with commas.

  • SET CELLULAR_DIRECT_ENABLED 1 
    SET CELLULAR_DIRECT_NUMBER_LIST "911","9911"

  • You can use multiple SET_CDNL= source numbers.

  • The maximum length of any individual SET_CDNL= entry is 63 characters.

  • The maximum length of the SET CELLULAR_DIRECT_NUMBER_LIST string is 127 characters.
