VP 300/PBX INTERACTION IN STANDARD DTMF INTEGRATION
This section explains how the phone system and the VP 300 interact when switching calls from the VP 300
port to a called station in standard DTMF integrated environments.
■
Primary and Secondary Answering
Figure 7-1 illustrates the interaction between the VP 300 and the PBX in a standard DTMF integration
installation, where both Primary and Secondary Answering modes are used. An explanation of
Figure 7-1 follows the diagram.
1. An incoming call is directed to the pilot number of the VP 300 hunt group for Primary
Answering (e.g., 2000).
2. The VP 300 plays the port level Company Greeting and prompts the caller to dial an extension.
3. After the caller dials an extension (e.g., 346), the VP 300 transfers to a ringing extension and
releases the port. If the greeting is ON, a transfer is not attempted, but instead the greeting is
played and the caller is immediately prompted to leave a message, dial another extension, or
dial zero.
4. On a no answer condition, the extension is programmed to automatically forward calls to a
different group of ports (e.g., 2500) for Secondary Answering. When the call is forwarded, the
PBX sends DTMF tones indicating the extension number that tells the VP 300 which extension
the call was forwarded from.
On busy condition, the VP 300 reconnects to the caller and offers to take a message.
5. The caller is told that the person (or extension 346) “is unavailable” and is prompted to “leave
a private message, dial another extension, or dial zero for assistance.”
