Configuring number manipulation for Digit Delivery
This number manipulation table defines the rules for changing the destination number received for
an incoming IP to Norstar call.
Digit delivery is a method used to automatically dial through to a target DN on the destination
Norstar system. You can configure the Norstar system to automatically answer certain lines. In this
configuration, the Norstar system provides a dial tone and waits for the caller to dial further digits,
as if they were a set on that system. These extra digits may be for a local telephone set or a local
PSTN call. If the destination digits received by the VoIP Gateway match a row of this table, the
digits will first be manipulated according to the rule in that row. They will then be dialed out after
the Norstar system answers the line. If a call does not match a row of this table, it is still connected
according to the IP to Hunt Group Routing Table. However, the Norstar system will not dial out
digits when the line is answered.
To configure the number manipulation for Digit Delivery:
1 Access the web interface.
2
Click the Protocol Management button.
3 Point to the Manipulation Tables tab and click the Digit Delivery Table link.
The
Digit Delivery Table
screen appears.
Note: The Save Configuration option is useful for trying out a new configuration.
Simply make the change and try out the new configuration. If you are happy with the
new configuration, save the changes to non-volatile memory. If you are not happy
with the new configuration, do not save the changes to non-volatile memory and
remove power from the VoIP Gateway. The VoIP Gateway will return to the previous
configuration.
Note: The Digit Delivery Table feature uses auto answer trunks to implement dialing
through to the destination target line. In order to use the Digit Delivery Table feature,
DTMF tone receivers must be available on the target Norstar system. DTMF receivers are
provided with a Services Card, Combo Card or E&M trunk card.
