Your Business Voice Security PIN (Answered)

Introduction


All Comcast Business Voice, VoiceEdge Select, Trunking (SIP and PRI), and Business VoiceEdge® customers will receive a unique account-level security pin (a “Security PIN”) that is required for managing certain voice features, accessing call detail records, and utilization reports. The Federal Communications Commission (FCC) mandates that this information, known as Customer
Proprietary Network Information or CPNI, must be protected by a password or Security PIN online.


If you call in to change certain voice features, such as call forwarding, you will be required to authenticate that you are an authorized user on the account and provide the Security PIN. Only the Primary Manager can unlock the account and view or change the Security PIN. Follow the instructions below to enter your Security PIN and unlock online features, or to edit or retrieve your Security PIN. Please call 1-800-741-4141 if you experience any issues concerning your Security PIN.


Enter your Security PIN and set security question


Sign in from a Comcast Business Internet connection


As a Comcast Business Internet and a new Voice Customer (Business Voice, Business VoiceEdge, VoiceEdge Select, or Business Trunking) customer, you can automatically authenticate CPNI access while connected to your Comcast Business Internet at your service location. Authentication happens automatically when you sign in to Comcast Business My Account for the first time with your email address and password from a wired connected device (preferred method) or a computer or mobile device connected to your Comcast Business Internet at your service location.

Authenticating your account allows you to access certain features, view call history, and view call detail records, without needing to enter a Security PIN. You will also be prompted to set up a security question and answer as an alternate means of authentication, in addition to the Security PIN. You can view and change your Security PIN or security question by following the instructions below. 


Note:
 For Business Internet customers with one or more Static IPs, it may take up to 24 hours after installation before automatic CPNI authentication can be performed.
