Working with Voicemail

Created by Jonathan Rees, Modified on Wed, 10 Apr at 10:12 AM by Jonathan Rees

Voicemail mailbox storage is limited to 100Mb. The number of voicemails stored within that limit will vary based on the length and content of the saved or left voicemails.

Accessing Voicemail

The Default Voicemail numbers are:


Internal from any extension on the PBX (User will be prompted for their extension number and password).


Internal from the extension of the User checking Voicemail (the user will only be prompted for a password).

Voicemail PINs

The following PIN numbers are blocked for security reasons and cannot be used in the Portal.

0000, 1111, 2222, 3333, 4321, 4444, 5555, 6666, 6789, 7777, 8888, 9876, 9999, 1234, 12345, 123456, 4321, 54321, 654321, 98765

Accessing Voicemail from Outside the Phone System

Get to your voicemail prompt by dialing a DID, or through an Auto-Attendant (AA). Once you hear your voicemail greeting press star(*) to be prompted for your password.

What is Enhanced Voicemail?

Enhanced Voicemail (also referred to as Enterprise Voicemail) is a treatment that gives the caller an option to try a different extension before prompting them to leave a message.

Note: Forwarding voicemail through the User Portal is a portal feature and will not trigger the Email Notification of the intended user the voicemail is forwarded to.

Call Flow with Enhanced Voicemail

  1. The caller dials a DID or extension number
  2. The caller hears the called party's voicemail greeting
  3. The caller hears "To dial another extension press 1, to leave a voicemail press 2 or simply stay on the line" (at this point, the caller can also dial 0 to reach the Operator extension).
  4. If option 1 is chosen and the domain has an auto-attendant, the caller will be directed to the auto-attendant and can dial another extension or choose the options available while in the AA menu. If the domain does not have an auto-attendant, a default prompt will play.
  5. If option 2 is chosen, the caller hears "Please leave a message after the tone".

Warning: Pressing 0 to reach the Operator extension is not enabled by default. To turn on you will need to set Operator Forward to which extension it will route to.

Sending Voicemail Alerts by SMS

It is possible to send voicemail alerts to a user's mobile phone by SMS using the mobile carrier's email gateway. Emails sent to a mobile phone via the mobile carrier's email gateway will be converted into an SMS message for the user.

To enable this functionality, simply add the mobile phone's email address to the User's profile in the PBX portal.

Note that Voicemail alerts by SMS are only plain text. It does not send the WAV file/link. The user has to log in to the portal or the device to listen.
