The default dial by name directory is the directory used when internal users dial *11. Your system comes ready with an internal directory (includes all extensions) that is assigned as the default. However, you can change this default directory to any other dial by name directory you have created.
1. Click System Settings in the left sidebar.
2. From the General tab > General section, browse for and select the desired default Dial-by-name Directory.
3. Click [SAVE].
