Incoming call routing - graphical overview
Lets you specify the call routing using a graphical overview. You configure the individual routing elements, thereby specifying the routing course.
Routing elements
The purpose of the routing element is to distribute incoming and outgoing calls to their destinations. Various call scenarios can be configured thanks to the large number of configuration possibilities. However, the standard configuration must be chosen in such a way that only a few settings must be modified for a standard call scenario.

Explanation |
Exchange connections |
An exchange connection comprises one or more network interfaces of the same type and the linked trunk group. In analogue exchange connections the call destinations are also specified. The trunk group configuration determines the connection properties of the network interfaces. |
Direct Dialling Plans |
Direct dialling is used to reach internal destinations directly from the public network (ISDN or SIP). For this purpose the incoming call number is linked with a specific call destination based on its DDI element. |
Routes |
All outgoing calls are routed to a trunk group via a route. They also include calls routed via the Least Cost Routing function and transit calls in a networked system. |
User groups |
In the user group, calls to a group are routed by internal destinations. The type of call distribution (global, linear, cyclic) can be configured. |
User |
User is synonymous with a configuration set with the user-specific settings. In terms of a configuration set, the unique identifying feature of a user is the internal call number. For the user as an individual person, the name (personal name) is the most important identifying feature. |
Routing itinerary for incoming calls
The routing course of an incoming call begins at the exchange connection on the left in the graphical overview, passes through the various routing elements and ends on the right at the user.
Default call routing: In the standard configuration, all calls are routed to user group 16. The first four users created are automatically entered as user group members.
Call routing without DDI: A call without matching DDI is routed directly to the call destination via the call distribution element assigned in the trunk group.
Routing itinerary for outgoing calls
The routing itinerary of an outgoing call begins at the user (on the right in the graphical overview), passes the route and is routed to the public or private network via the exchange connection.
