Current customers with Centrex lines will receive an email notice about the upgrade on January 17, 2011.
If you are a current customer with Centrex lines, these may be your primary phone service, your primary service but behind a telephone PBX, key or hybrid system or simply provide power failure back-up and specialty lines. Any telephone number beginning with 612-627- is a Centrex line. Having extension numbers or multiple lines on individual phones would indicate that you are on a key or hybrid system along with Centrex. If you are on one of these systems, it is important to know that directions associated with your telephone equipment will not change. If you use Centrex lines behind specialty equipment, such as fire, security or monitoring equipment, please check with your equipment vendor as to whether an interruption in dialtone will affect their service to you.
