Special Modes
Deactivating Least Cost Routing (LCR)
This feature cannot be used with a SIP terminal.
H## Z (dialling code, call no.)
For enquiry calls:
GR## Z
(dialling code, call no.)
If you wish, you can deactivate Least Cost Routing, which always uses the cheapest
route for a call, and select a network operator yourself (this is known as “call by call”).
This procedure is only necessary if LCR is activated in the OpenCom 100 / Aastra 800
for your user group.
Calling Selectively via Routes
H Z
(routing code, call no.)
For enquiry calls:
GRZ (routing code, call no.)
A call to a desired party is set up automatically or selectively via routes in the
OpenCom 100 / Aastra 800. Your system administrator configures these routes in the
OpenCom 100 / Aastra 800 and defines the assignment of each route. By
selectively
dialling the routing code prior to the (internal or external) call number, you manually
select a route for a particular call.
Selectively calling via routes allows you to reach parties in the branch offices of a large
corporate network, for example. By manually entering a routing code, you can also
administer the tariff charge data for private and professional calls separately.
Your system administrator will inform you of the current routes and their
routing codes.
