ScenarioYour customer may like to have the Message Waiting Indicator (MWI) for a shared voicemail account be activated on multiple phones. You can accomplish this by creating the shared account as an additional line on the desired extensions.Note: All devices connected to a Shared Voicemail account will impact the MWI status.For example, if a total of three devices are connected to a Shared Voicemail and one of those devices listens to a voicemail and then saves or deletes it, the MWI will turn off on all three devices.Configuration StepsCreate a User called "Shared Voicemail"Create a separate device for each extension that wishes to monitor this account. Assuming that the shared voicemail User is 100 and this needs to be shared by extensions 200, 201, and 202, then you will need to create three devices for User 100 (eg. 100, 100a and 100b).Add one of the User 100 devices as an extra line on the main device for each of the other Users (eg. User 200 will have device 100 as an extra line, User 201 will have device 100a as an extra line, etc.).CostThis configuration will cost one (1) seat license to add the device(s) to the "Shared Voicemail" user, so you may interact with the voicemail from the convenience of the same hardware device for multiple extensions.NDP ViewOverride View for Yealink Phones#LINE KEY APPEARANCE - The User's ( Ext 200) extension is normally in the first button position.linekey.1.type="15"linekey.1.line="1"linekey.1.label="Ext 200" or "Line 1"#SPEED DIAL Button to access the 2nd account (Ext 100) for the General Voice Mail.  The .line key should match the "Phone Extension #" in the NDPlinekey.3.type="13"linekey.3.line="2"linekey.3.value="5001"linekey.3.label="General VM"Visual NavigationChoose to "VIEW" the voice mail for either account.
