OCTEL 200/300 PBX INTERACTION IN STANDARD DTMF
INTEGRATION
This section explains how the phone system and the Octel 200/300 interact when switching calls from the
Octel 200/300 port to a called station in standard DTMF integrated environments.
Primary and Secondary Answering. Figure 1-1 illustrates the interaction between the Octel 200/300
and the PBX in a standard DTMF integration installation, where both Primary and Secondary Answering
modes are used. An explanation of Figure 1-1 follows the diagram.
Figure 1-1 Octel 200/300/PBX Interaction — Standard DTMF Integration, Primary
An incoming call is directed to the pilot number of the Octel 200/300 hunt group for Primary
1
Answering (e.g., 2000).
The Octel 200/300 plays the port level Company Greeting and prompts the caller to enters an
2
extension.
After the caller enters an extension (e.g., 346), the Octel 200/300 transfers to a ringing
3
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, enters another
extension number, or presses zero.
On a no answer condition, the extension is programmed to automatically forward calls to a
4
different group of ports (e.g., 2500) for Secondary Answering. When the call is forwarded, the
PBXsends DTMF tones indicating the extension number that tells the Octel 200/300 which
extension the call was forwarded from.
On a busy condition, the Octel 200/300 reconnects to the caller and offers to take a message.
The caller is told that the person (or extension 346) "is unavailable" and is prompted to "leave a
5
message, enter another extension number, or press zero for assistance."
