Yes, but the level of voicemail integration differs between Microsoft Exchange and Google Mail. 

Microsoft Exchange
The Carnegie Mellon phone system is fully integrated with Microsoft Exchange. The phone system stores your voicemail messages and synchronizes them to your Exchange mailbox, then replicates your actions between the two.
  • You receive an email when you have a voicemail message. Open the email attachment to listen to your voicemail message.
  • Your original voicemail messages remain in the phone system. You can access your messages from your telephone, from Voicemail Manager, or from Cisco Jabber.
  • If you listen to, save, or delete a voicemail message from your email account, the system marks it as listened to, saved, or deleted in your voicemail account, and vice-versa.

G Suite
The Carnegie Mellon phone system cannot be fully integrated with G Suite's Google Mail. However, there are two ways you can receive voicemails in your Google Mail account. Contact Computing Services to set up either option.

  • Receive a copy of your voicemails in your Google Mail account. 
    The original messages remain in the phone system. You can access them from your email, your telephone or Voicemail Manager

    Your voicemail messages are not synchronized with your email account. For example, if you delete a voicemail message from your email, it is not deleted from the voicemail system.
  • Forward your voicemails to your Google Mail address. 
    The original messages move from the phone system to your Google Mail account. 

    You can access your voicemail messages only from your email, not from your telephone or Voicemail Manager. You will no longer see a red light on your phone, which indicates that you have a voicemail message. 

If you use Microsoft Exchange, your system administrator may have configured your phone to send an email message when you receive a voicemail. When you click the attachment in the email, the voicemail plays. As with any email and attachment, use caution when opening. If you suspect a phishing attempt, check the full email header before opening the message.

An email header, usually hidden, is a block of information about the message that includes the sender, the recipient, the date, sending and receiving time stamps and the servers that handled the transfer of the message. To view and check an email header for the most commonly used email clients, follow these steps.

  1. Visit the CMU Information Security Office website and follow the instructions to view the full header for your email.
  2. In the email header window, search for these exact terms: Received or Received-from. If you find one or both terms in the header, the email may be a phishing message. Do not open the attached voicemail. Instead, do one of the following:
