Comcast Business Voicemail overview

Updated 7/26/2018 9:07:13 AM by Comcast Expert


When you are on the phone or offsite, Comcast Business voicemail helps you to stay on top of your voicemail so you don't miss an important message.


Set up voicemail

You can access your voicemail by phone or online anywhere in the world. For security purposes, you must use your office phone to set up and activate your voicemail. We recommend that you change the default password and create a personalized greeting that your callers will hear when they reach your voicemail.

Please note that each line has its own voicemail, and will need to be set up individually.

Activate voicemail

First time activation of your voicemail must be completed from your office location. After activation, you will be able to access your voicemail by phone or online, from anywhere. 

  1. Dial *99 from your office telephone.

  2. You will be prompted to enter the default password, which is the last four digits of your telephone number.

  3. Once you are in the system, listen carefully to the recorded instructions. An audio tutorial will guide you through the setup of your new voicemail service. You will be prompted to create a password, record your name and record a customized business greeting.

    If dialing *99 does not work from your office phone, plug the office phone directly into the Comcast Business Voice modem and try the activation instructions again. If the issue persists, please contact Comcast Business Support at 1-800-391-3000.
