Forwarding of Call Request to external telephone

This article describes how a Call Request can be forwarded to an external telephone via a SIP Gateway. Two types of call forwarding are described:

• Manual Call Forwarding: The Call Forwarding is switched on and off by the operator by dialling a code or pressing a DAK key.
• Automatic Call Forwarding: If the Call Request is not answered within a programmable time, the calling station is connected to the telephone

You can choose to use both types of forwarding, or only one of them.

The call to the telephone will be activated only if there is a free telephone line. If all available lines are busy, the system will retry every 5 seconds until a line is free.

There will be no redial if the telephone subscriber is busy. Also there is no option for dialling of alternative telephone numbers.

AlphaNet: The programming described in this document will also work in AlphaNet systems. The calling stations, the queing station and the SIP gateway can be located in the same node or in different nodes in the network.

Software requirement: AMC 11.2.3.3 or newer.

Manual Call Forwarding

The Call Forwarding is turned ON and OFF from the Queuing Station.

• Call Forwarding ON: Dial 7870 + Dummy Number (e.g. 7870 + 5152). The dummy number can be any station directory number in the exchange that is not in use. In this article 5152 on physical 552 is used as an example.
• Call Forwarding OFF: Dial 70
