How do I know when I have a voicemail message?
In your Home view, you can see all of your incoming and outgoing communications right above your chat messages. Look for an icon that looks like a recording with a timestamp.
You will also get a count of missed messages in the My.OnSIP browser tab.
Go to your Inbox view and click on a voicemail item (same icon as mentioned above). Then, simply click the play button that appears on the right half of your screen. If you wish to delete the voicemail, click the X and confirm by selecting 'Delete'.
