oice Mail Integration
Description
This system can accommodate Voice Processing System (VPS)
equipment, which offers the user Voice Mail (VM) and Automated
Attendant (AA) Services. If an extension user has set the Call
Forwarding destination to the VPS, the calling party will be
forwarded to the VPS and can leave a voice message in the mailbox
of the extension. When a call is transferred to the VPS by Call
Forwarding or Intercept Routing – No Answer (IRNA) features, the
mailbox number is sent to the VPS automatically with DTMF (Dual
Tone Multi-Frequency) signaling (Follow On ID). Up to twelve
extension jacks can be connected to VPS as extensions in the
system.
System Explanation
1. Voice Mail Service
1.1 Call Forwarding to VM
If an extension user sets Call Forwarding (C. FWD) whose
destination is the VPS, an incoming call is forwarded to the
VPS under the proper conditions. The system sends to the
VPS a mailbox number of the corresponding extension at that
time. Therefore the calling party can leave his / her message
in the mailbox of the desired extension without knowing the
mailbox number.
