I have an issue were an extension is a member of a shared mailbox, which is working fine, but if a message is left in the users personal mailbox 1st and then another is left in the shared mailbox, once the user has listened to the 1st voicemail message, the lamp is tuned off and does not indicate that there are still messages in the other mailbox, this is the same if the group voicemail was 1st, then the lamp does not show that there are still messages in the personal mailbox. The messages are still there though and in the case of a group mailbox the lamp remains lit on the other extensions.
The customer is using SNOM handsets.
Any one come accross this before?
