VoiceMailInterface

EnableVMURI
The device supports the following digital PSTN-based MWI features:

ISDN BRI: The device supports MWI for its BRI phones, using the Euro ISDN BRI
variant. When this feature is activated and a voice mail message is recorded to the
mail box of a BRI extension, the softswitch sends a notification to the device. In turn,
the device notifies the BRI extension and a red light flashes on the BRI extension’s
phone. Once the voice message is retrieved, the MWI light on the BRI phone turns off.
This is configured by setting the VoiceMailInterface parameter to 8 (“ETSI”) and
enabled by the EnableMWI parameter.
