Our local area code will have any overlay from the phone comapnay which means our area code will require every caller to dial 1+ the area code and number for local and long distance calls. I tried entering the 1XXX in LD 90 but got a ESN 073 code. My are code is the home NPA and I need to know how to change or delete the home NPA and insert the area code into LD 90 or is there another way of achieving this.
