Voicemail - Single Inbox / Speechview (SIB/SV)

Single Inbox / SpeechView (SIB/SV) is a new feature for users who currently have a voice mailbox on the CU Boulder campus telephone system. This feature functions for phone lines associated with a single user identikey. For group voicemail and email requests, please have your Telephone Liaison submit the SIB/SV Request from. Use the Telecommunication Liaison lookup tool if you do not know your liaison.

This service provides an alternative way of receiving and listening to your work voicemail. In addition to dialing into the CU Boulder voicemail system to retrieve messages, messages will be delivered to your Exchange email inbox in a speech-to-text transcription as well as a .wav audio file attachment. 

Single Inbox/SpeechView is a service offering available only to campus faculty and staff who are using the OIT Exchange Online email service. If you are using an email service other than this, the SIB/SV service will not function. This service also does not work with accounts that forward to an off-campus email service.

Security Notice 

To prevent the written transcription and email transmission of highly confidential information, the SIB/SV feature is prohibited for any user who may receive this type of information by telephone. Visit the Office of Information Security (OIS) website for more information about highly confidential information.

If you handle highly confidential information, callers should be warned not to leave sensitive information on your voicemail. When recording your greeting, please include a reminder, such as, “Please do not leave any confidential or sensitive personal identifiable information on this voicemail, as it is not set up to protect such information.”

If you have security concerns or questions, please visit the Office of Information Security (OIS) website or send an email to

How SIB/SV Works: 

Every time you receive a new voicemail message, you will receive an email with a .wav file attachment and a text transcription of the voicemail message. You can view and/or listen to your voicemail message from email on your computer (PC/Mac) or mobile device.

*Note: The transcription is automated, so it may contain inaccuracies.

When you open the email that contains the voicemail message:

  • The voicemail message status on your desk phone will automatically change to “saved"
  • The message light on your desk phone will change from illuminated red to unlit
  • Both will occur even if you do not listen to the .wav file (Simply opening the email will cause the status change from “unread” to “saved,” but will not delete the message)
  • There may be a short delay before these changes take place

When you delete the email with the voicemail message: 

  • The message status will change to “deleted”
  • The message light on your Cisco phone will become unlit
  • Both will occur even if you do not read the email or listen to the .wav file
  • There may be a short delay before these changes take place

When you delete the voicemail message using the telephone: 

  • The email with the voicemail message will also be deleted.  It will be available in your “Deleted Items” (trash) until it is permanently deleted from the email system
  • There may be a short delay before the email is deleted

Emails with voicemail messages from outside callers will show: 

  • From: Cisco Unity Connection Messaging System <>
  • To:
  • Subject: Message from Unknown sender (caller-phonenumber)

Emails with voicemail messages from callers on CU Boulder campus will show: 

  • From: Caller Name <>
  • To:
  • Subject: Message from Caller Name (caller-extension)
  • If you wish to reply to the message via email, you can Forward the message with your response to the caller’s actual email address.

*Note: Your voicemail inbox has limited storage space. If you do not regularly delete the emails with SIB/SV messages, your voicemail box may reach capacity, and callers will not be able to leave new messages. To alleviate this issue, you may choose to archive the email messages. You can either save the .wav file in another location, or forward the email message to yourself and then save the forwarded message.
