Voicemail

For Voicemail to work, the Horizon Company needs the Voice Portal to be set up first.

  • Voicemails have a 30-day limit. This applies to all messages left on the voice portal, including saved messages. If you wish to save certain messages, we recommend using the “Notification Settings” when editing a user to send an email with a file of the voicemail by selecting “Notify Me at the address”.
  • The capacity on a voicemail is 100 minutes. After this, the caller will be unable to leave a voicemail message.
  • The user can skip to the end of the voicemail message by pressing 6.

Setup Voicemail from a handset #

You can set up voicemail directly from a user’s handset, including personalised name greetings, No Answer greetings and busy greetings. This can be applied to both a user or group telephone number.

Step 1

Dial the company Voice Portal and enter the user or group extension number when prompted for an ID.

Step 2

Enter the passcode of the user/group.

If the user does not know their password, then this can always be reset in the “Edit User” tab on the Horizon Portal.

For a hunt group the passcode can be manually set in the “Edit Hunt Group” page under the Voicemail tab.

Step 3

If the user is accessing this voicemail box for the first time, then the Voice Portal will ask the user to change the passcode.

The Voice Portal will then proceed to ask the user to record a personalised name greeting. The user must do this in order to proceed.

Step 4

After this is complete the user should be presented with the following message:

“You are now ready to use your voicemail system. To access your voice mailbox, press 1”.

Press ‘1’ to listen to your messages, to change ‘your mailbox busy greeting’, press ‘2’ and to change ‘your mailbox no answer greeting’ press ‘3’.

Step 5

Finally, you will need to specify on the Horizon Portal what message you would wish to use during “No Answer” and “Busy” actions

To ensure the caller is aware of the transfer option this feature provides, it is important that the user records an appropriate voicemail message such as the following example:

“Hi, you’re through to the voicemail of ___. I can’t take your call right now so please leave a message and I’ll get back to you. Alternatively, press 0 to be transferred to the Service Desk”

This voicemail greeting should advise that the feature is available to the calling party in addition to programming the destination number.
