Hi there. I'm having an issue regarding the Message Waiting Indicator (MWI) when a new voice message is sent to a specific user voice mailbox. The extension to turn on the MWI is 8901 and is working. 8902 turn it off. But nothing happens on the IP Phone with a new voice message on the voice mailbox. Using CUCMBE 6.0(1), Cisco Unity 2.1. Everything is enabled on Unity regarding MWI, the integration with the phone system too. Any ideas why the MWI doesn't turn on in the phone? Thanks.
