*** Unfortunately voicemails cannot be "undeleted" or recovered once deleted. ***

The moment a voicemail is deleted it is permanently unrecoverable by IT Services or our hardware vendor Total Communications.
If you anticipate having a need to review old voicemails consider selecting 5 (save) after listening to each voicemail instead of 3 (delete).

You may look up your most recent call history via the Mitel MiCollab program on your office PC or you can access via website version of the Mitel Program. General Mitel software info including call history below:
