Common/Customer Diversion Numbers

A common diversion number is a number of a divertee position which is common for the entire system.

A customer diversion number is a number of a divertee position which is common for a specific customer.

In this section common will be used for both common and customer diversion.

A separate setup of common diversion numbers exist for message diversion.

The system may have up to four common diversion numbers per customer:

Common diversion number for internal calls.
Common diversion number for calls within a private network.
Common diversion number for calls from a public network.
Common diversion number for calls originating from individual operators internally, or in a private network.

The common diversion numbers for message diversion are utilized for the facility message diversion. The common diversion numbers (ordinary) are utilized for the facility direct diversion provided that the extension lacks an individual diversion position. They can also be utilized for diversion on busy and diversion on no answer if a general individual diversion number (see Individual diversion numbers) is initiated but not valid for the current call origin.

Direct diversion means that an incoming call to a voice extension, internal group hunting group (PBX) or common bell group will be diverted to one of the common divertee positions.

Message diversion means that a call to a voice extension will be diverted to one of the common divertee positions provided that the latter is a message divertee position, mailbox port or common PBX operator group.

Regarding configuration of message divertee positions, see the Operational Directions for INTERCEPTION SERVICE.

The activation or cancellation of an internal direct diversion for a voice extension is carried out with a procedure and can be executed from the origin position, a PBX operator or CSTA application request.

The activation or cancellation of a network direct diversion for a voice extension is carried out with a procedure and can be executed from the origin position, a PBX operator or CSTA application request.

Activation/cancellation of an internal direct diversion for an internal group hunting group (PBX) can be executed through a procedure from the divertee position, a PBX operator or CSTA application request.

Activation/cancellation of a network direct diversion for an internal group hunting group (PBX) can be executed through a procedure from a PBX operator or CSTA application request.

The common divertee position may be:

an individual PBX operator
a common PBX operator group
voice extension
internal group hunting group (PBX-group)
procedure
an external number within a private network of type SIP/H.323/ISDN/DPNSS

The following table shows to which common divertee position a call is diverted, with regard to the origin of the call and which of the common divertee positions are initiated in the exchange
