General information and limitations

  • To store Voicemails on Virtual, Hardware PBX, the backend to store all the PBX data and a partition for Voicemail must be added in WMS Settings -> System -> Storages. More information: WMS Start Guide (Storage services).
  • Maximum number of Voicemails per user: 100
  • Maximum number of Voicemails per system: not limited (limited only by available disk space)

Set up call forwarding to Voicemail

Forwarding to Voicemail can be set up by user in user settings (Collaboration / WMS) or by system administrator in Dialplan. 

Call forwarding to Voicemail - personal settings

In Collaboration -> Settings -> Features users can set up call features per call type (internal / external / blacklist / whitelist) and based on the current user status (available / do not disturb / away). 

If "external", "blacklist" and "whitelist" classes are not activated ("Activate class" tick is off), behavior is inherited from "internal" class. If "do not disturb" and "away" is not activated ("Activate class" tick is off), behavior is inherited from "available" status. More information: Collaboration - User Guide (Settings - Call features).

Example1: "Do not disturb" / "away" tick is off - this means when user status is dnd and user is busy on the phone, calls are forwarded to Voicemail (in the first column for "available" status Call Forward Busy: VOICEMAIL is specified):

Example2: "external" class is activated only for "away" user status, this means, for "available" and "do not disturb" status behavior will be inherited from "internal" call class, and only in case user status is "away", all external calls will be forwarded to voicemail (Call Forward All: VOICEMAIL):

Call forwarding to Voicemail via Dialplan

Dialplan application "Go to Voicemail" allows routing calls to Voicemail. As destination it is possible to add one or multiple extensions and email addresses. For more details refer to the guide Dialplan applications

Use case: normally this application is used with Switches and Timetables, allowing routing of incoming route calls to Voicemail in case the office is closed. You can learn more about setting switches and timetables in WMS Start Guide (Dialplan practical examples -> External Dialplan: main).

Dynamic call forwarding to Voicemail

Users can forward a ringing call / an active call to Voicemail at any time via Collaboration:

  • Send a call to your own Voicemail: upon receiving an incoming call (or during an active call) press Transfer button from the call dialog window and then press the Voicemail icon
  • Send a call to a colleague’s Voicemail: upon receiving an incoming call (or during an active call) press Transfer button from the call dialog window, enter a colleague’s name or extension number into the search field, and then press the Voicemail icon near the name of the colleague

Note: in case call is sent to VM before answer, greeting is played; in case call is sent to VM after answer, only beep is played.

Shared Voicemail

Shared Voicemail feature works only for users of the same PBX (not in WMS network).

Wildix system supports two ways of subscribing to someone's Voicemail:

  • BLF / Feature key "Voicemail" supported on WP480G 2017 / WP490G 2017 (r3) / Start / WelcomeConsole / WorkForce (recommended): allows you monitor and listen to Voicemail of the selected user (when new message received, BLF LED turns steady blue)
  • "Shared Voicemail" feature in WMS -> Users -> User preferences (old): subscribes you to the mailbox of the selected user (no access to personal mailbox via WP phones XML browser) 

Shared Voicemail BLF key

Feature works only for WP480G / WP490G 2017 (r3)/ WelcomeConsole/ WorkForce / Vision / SuperVision.

(BLF key is displayed in Collaboration -> Fn keys menu starting from WMS 5.02.20201116.5)

Note: Starting from WMS 5.02.20201015.2, the BLF "Voicemail" can be used for viewing missed Call group calls and voicemails notifications. Check the documentation How to set up the Call Group notifications manager feature for details.

For USA/ Canada PBXs Voicemail is protected by PIN by default. This affects all the cases: access via Feature Code 81, access via XML by pressing Voicemail button, access to shared Mailbox via BLF key "Voicemail" etc.

To access Voicemail, users have to enter their PIN (PIN = the first 5 characters of the user's WEB password).

How to enter the PIN code from the phone:

  • to enter any letter (lowercase or uppercase) or digit, press once the corresponding alphanumeric key once (no need to press the key several times to find the exact letter)
  • to enter any special symbol (pound included), enter the * (star) symbol

You can disable the PIN protection by adding ACL permission "can use" - "voicemail without pin code" in WMS Users - Groups.


  • Add ACL permission "Can see - Voicemail - group" (Specify group) (in WMS -> Users -> Groups)
  • Add Feature key "Voicemail" and specify user (via Collaboration or WMS). More information: Collaboration - User Guide (Settings - Function keys)

When monitored user receives a new Voicemail, BLF LED turns steady blue until the owner or the subscribed user reads the message (or marks it as "read").

Both the mailbox owner and the subscriber can delete Voicemails from WP phones XML browser interface.

Important: ACL rule "Cannot use - Voicemail" has higher priority than "Can see - Voicemail", read ACL rules & Call classes management Guide for details.

Known issue: in failover scenario (TCP / 443), BLF subscription is sent only once. More on Failover scenario: Failover Guide.

Limit access to Voicemail

Limit access to Voicemail for users 

By adding a rule in WMS -> Users -> Groups - "Cannot use - Voicemail" you can restrict access to Voicemail via Collaboration, Feature code, Wildix Phones, Vision, SuperVision, WP600AXX, iOS/ Android apps. 

More information on ACL permissions: ACL rules and Call classes management - Admin Guide.

PIN protection

Added new ACL (in WMS -> Users -> Groups): "Can/ cannot use voicemail without pin code”

By default this ACL is disabled (which means, users can use voicemail without PIN code).

This ACL restriction is present by default for the USA and Canada.

This ACL does not affect Collaboration (which means, even if the restriction is present, users can still access their Voicemail from Collaboration without having to enter PIN code)

To enter PIN code from Wildix phones:

Enter first five symbols of your user password. Note: press once the star * symbol in place of any special characters (*#$^& and others). Press once a corresponding alphanumeric key in place any minuscule and majuscule letter. E.g. press 2 to enter 2, a, A, b, B, c, C.  

Restrict "Shared Voicemail" BLF

Feature is disabled by default. To start using this feature, it is necessary to

  • add ACL permission "Can see - Voicemail - group" (Specify group) (in WMS -> Users -> Groups
  • make sure ALC "Cannot see - Voicemail" is not present for this group of users.

Exit Code "0" from Voicemail allowing caller to speak with an operator

Use case: someone has reached the company and the call was sent to Voicemail, caller can hit 0 at any time to speak with an operator 

How to enable it:

  1. Add the parameter operator=yes to the file voicemail.conf (More information: Custom config parameters List)
  2. Add the letter ‘o’ as called number to the Dialplan context (add "o" as called number and under it add "Dial the phone" / "Call group")

Dialplan example:

The "o" entry must be added to all originating Dialplans that a call arrives in, where you want the user to be able to utilize the 0.


  • In "main" Dialplan if you want callers coming in from a SIP trunk to be able to press 0
  • In "users" Dialplan if you want internal users that are assigned to the "users" Dialplan to be able to press 0

Auto-deletion of Voicemails

The option to auto-delete Voicemails after a certain period of time is present in WMS Settings -> PBX -> Call and chat history

Access Voicemail from the outside

It is possible to allow access to Voicemail from any external phone number using Dialplan application "Voicemail access". By default Voicemail is protected by PIN. You can disable PIN protection in Dialplan application settings. Read more in the guide Dialplan applications

Use case: user of the system would like to check his/her Voicemail from outside, by dialing a company phone number. They dial the company phone number, dial some digit to access their Voicemail and enter their PIN.

Voicemail statistics

Via CDR-View it is possible to see the statistics on the Voicemails received by the users of the system. More information: CDR-View User Guide.

Developer: Voicemail APIs
