We are now using Unity 4.2(1) integrated with Traditional PBX. I found that MWI behaviour is that it only send MWI-On to subscriber for the 1st new message. We encountered some cases that the the Message Lamp was not lighted for the 1st message. After that, he/she got many voice messages and he/she was not notificed by MWI.
Is there any setting that the system can send MWI-On for every new message (for particular user)? Thanks!
P.S. we already set the system to send MWI-On/Off twice for every notification
