Whenever voicemail is accessed for a mailbox (message leaving or retrieval) voicemail sends a voicemail status update for that mailbox to the PBX. This is traced out within System Monitor with the MonIVR option and is an IVR Event type message.
The following is a trace example received with leaving a message to mailbox 206:
IVR Events indicate the number of new, read, saved messages. If the new message count is zero then the PBX should extinguish the message waiting light, otherwise the message waiting light should be activated.
When the MWL indication is sent to the phone, the CMExtnTx event should indicate the transmission of the message CMVoiceMailStatus with the number of new messages being in the display field (may also be in the calling party field). The UUI field may also contain the information format (length of UUI, number of messages, unread messages, extension state).
