7.2 External Routers
External routers use the External Routing Machine (ERM server) for call and SMS
routing. The ERM server partially replaces or complements the internal 2N NetStar
®
routing mechanisms. Having received a call/SMS routing request, the PBX sends a
query to the ERM server. If a matching record is found in the ERM server database
table, the ERM server sends back a parameter specifying further call/SMS routing in
the external router. DB connectors, which are used for setting communication with the
ERM server, are an inseparable part of the external routers. Refer to the Network –
menu for DB connector settings. DB connectors
The menu consists of two windows. The left window Routing – External routers
includes a list of available external routers. The right window helps you configure the
selected external router. The context menu opened in the left part of the menu offers
the following options:
Add – display the router adding window and enter the router name.
Delete – remove the selected router including all database links associated with
this object.
Delete all – remove all the routers listed. You will be asked for confirmation
before deleting.
Rename – rename the existing router. If you enter an existing name, you will be
warned and no change will be executed.
Add router group – add a new group of routers.
Add router subgroup – add a subgroup to the currently selected group of
routers.
Move to root level – move the selected object to the highest level beyond all
existing groups and subgroups.
Move group content – move the whole content of a group or subgroup to
another group or subgroup of routers.
Copy router – all you have to do to copy the currently selected router is enter a
new name here. The copied router contains the same records as the original one
(including the default destination).
Show objects routed to router – display a side window for the selected router
inclduing a listing of all objects routed to this router. This function is useful for
PBX routing checks.
Expand all – unfold the whole router group/subgroup structure easily.
Collapse all – fold the whole router group/subgroup structure easily.
Call Routing
The process of call/SMS routing via an external router is simialr to that via an internal
router. The only difference is that the external router uses a single input parameter,
i.e. the Parameter. If the parameter value obtained from the ERM server is identical
with the value included in an external router row, routing to the specified destination is
executed.
