Voicemail and Unified Messaging Features
- Email notification of message arrival
Notification with or without the voice mail as a wave file attachment. Subscribers can review messages on their PC and forward voicemails to others via email. - Rapid call return
Allows subscribers to listen to a voice message then have the system call the party who left the message. Once the call is ended, the subscriber is returned to the same point in the voicemail system. - Access to subscriber interface from deposit menu
Allows subscribers to call into the deposit interface of their mailbox, then enter a DTMF sequence to switch to the subscriber interface. The subscriber presses the star (*) key while listening to the deposit greeting, the system prompts the user for the voicemail password and, if validated, transfers them to the subscriber interface. - Prompt cut-through
The system allows experienced subscribers to enter star (*) during the greeting and immediately enter their password, to save time. Subscribers can also enter DTMF selections without waiting for menu prompts. - Skip-forward and skip-back
Subscribers can skip forward or back within a message, or skip to the beginning or end of a message. - Configurable greetings
Subscribers can choose from four different voicemail greetings: - System default greeting with the phone number
- System default with a recording of the subscriber's name
- Personal greeting recorded by the subscriber
- Alternate temporary greeting (vacation message, etc.)
- Class-of-service definitions
Service providers can configure voicemail offerings with different classes of service. Attributes that can be controlled at the class-of-service level include maximum length and number of messages that can be stored, greeting length, and number of days that a message can be stored before being automatically deleted. - Message Waiting Indicator
SIP-based message waiting indicator is supported for SIP phones, in accordance with RFC 3842
