Group Voicemail

PBX Manager

add group voicemail

New Input to define the users who want an MWI. It is a comma-separated list of SIP names. The list of SIP names is added to VM PBX Object. For this, the new URL parameter is "$_m". A new URL parameter is also added to the VM PBX Object for app support. It is needed to define that this VM PBX Object is a group voicemail.

configure MWI on Phone


Voicemail XML Script

The PBX should be able to load the vm.xml file from the Voicemail App Service. Therefore the credentials(User, Password) under Tab Voicemail, must match with the credentials configured in the AP voicemail_xx-plugin of the PBX-Manager (Settings-section). Changing these credentials can be done best via the AP voicemail_xx-plugin of the PBX-Manager, as this plugin will adjust all the necessary (Voicemail-object and database-record of the Voicemail-instance).

To trace, if PBX can read the Voicemail XML from App Platform, activate the Trace flag on the Voicemail Object, PBX Trace in the Maintenance/Tracing, and make a call to the Voicemail to see if the vm.xml is transmitted correctly.

App WebSocket

The PBX should maintain a permanent WebSocket connection to the Voicemail App Service. On the Voicemail Object, under Tab Voicemail', check if Script URL show connected state. The Voicemail-objects password in the 'General'-tab is being used for this and checked against the Voicemail-instances password.

If not, check if the URL is correct and points to the service instance. The PBX should be able to resolve the DNS name and be able to connect to the Voicemail App Service on the App Platform. If all OK: re-configure the password on the instance and voicemail-object.
