Basic administration for Central Office (CO), Foreign Exchange (FX), and WATS trunk groups is identical, so we’ve combined instructions for all 3 in the following procedure. In most cases, Avaya recommends leaving the default settings in fields that aren’t specifically mentioned in the following instructions. Go to the Avaya Support website at http://support.avaya.com for more information. Your settings in the following fields must match your provider’s settings:
  • Direction
  • Comm Type
  • Trunk Type
Caution:
Use the list above as a starting point and talk to your service provider. Depending on your particular application, you might need to coordinate additional administration with your service provider.
