This page displays all the configured routes for phone calls. Routes may be changed added or deleted. The display of routes can be filtered so that only routes with a given From or To interface are displayed. For incoming calls these routes are searched from top to bottom to find a matching route. So the sequence of the routes is important. If a VOIP registration is configured for a physical interface the required routes to send calls from the physical interface to the implicitly generated VOIP interface and vice versa are generated automatically. These automatically generated routes are displayed with grey number maps.

Automatic Route

When registering an interface to a PBX, corresponding routes are automatically created. These routes allow to decide where calls shall be sent to (e.g. another interface, PBX) depending on the CDPN. Also they allow to further manipulate the incoming and outgoing CDPN and CGPN.

Such an automatic generated route will always create a logical enpoint representing the PBX. This special endpoints are named according to the interface that created them, i.e. RB[1-2] (BRI) , RT[1-4] (TEL), RP[1-4] (PRI) and RAB[1-8] (analog TEL). Even though the names are slightly different, they have in common that always represent the PBX as routing endpoint.


The routing table consists of a ordered list of routes. Each route defines a list of interfaces for which incoming calls are handled by the route and a list of maps. The maps define the called party number which are matched to the incoming call, the new called party number, some flags, the destination interaface and optionally a list of calling party number maps. The calling party number maps are used to modify the calling party number of the call.

Insert Routes

Routes are inserted by clicking on the left insert symbols. The new route is inserted below the symbol. A edit page is opened which is used to enter the parameters for the first map of this route.

Insert Maps

To insert maps the insert symbols displayed before the number maps are used. There is one "insert above" symbol to insert a new map as first map of the route.

Filter List

If a From interface is clicked only the routes which contain this interface as From interface are displayed. If a To interface is clicked only maps with this interface as To interaface are displayed. These mechanisms can be used to figure out what is going on in big routing tables.

Change Maps

Maps can be changed or deleted by clicking on the number maps (which is just an arrow if the map is empty).

Changing CGPN Maps

The Calling Party Number maps can be changed by clicking on a CGPN Map. An edit page is opened by this which contains all the CGPN Maps of the given Map.
