Alternate voicemail deposit notification for roaming mobile devices

摘要

Systems and methods allow a roaming mobile device to communicate with a visual voicemail (VVM) system to inform the VVM system of its roaming status. The VVM system then suspends VVM service for the voicemail account associated with the roaming mobile device and instructs a notification server to notify the roaming mobile device if a voicemail message is deposited into a voicemail box associated with the voicemail account.
