When you receive a new voice mail message, the Message Waiting Indicator (MWI) should glow or light up. However, when you are using a third-party messaging server, the MWI in Avaya Vantage™ Connect does not light up.
Cause
This issue occurs due to a third-party server limitation. This issue does not occur if you are using an Avaya MWI server.
Solution
None. You can still listen to the new voice mail message. If you use an Avaya MWI server, the MWI in Avaya Vantage™ Connect lights up as expected.
