Nortel Networks NN43001-121 manual Telephony Gateway and Services planning

66Planning and engineering

If calls that enter the Call Server are international and outside of the country of the caller, the translator must contain entries that recognize the international numbers and route the call to the appropriate route list. These entries are generally within the existing AC1/AC2 translator, as they are used to route international calls that are dialed directly from telephones.
