Telephoning
Keypad Dialling
A number of European network operators need the keypad protocol in order to set
features. Depending on your system configuration your telephone could be set to
keypad dialling during the connection state. If this is not the case, you must switch
your telephone over to the keypad protocol – before dialling – and enter the code
digits specified by the network operator. These are transmitted directly to the
exchange and evaluated there. You usually get an announcement as an acknowl-
edgement. Consult your system administrator if you have questions concerning this
function.

This switches your telephone over to the keypad protocol. You can now enter the
code digits for the appropriate keypad.
Note
The setting is deleted again when the connection is terminated!
Least Cost Routing (LCR)
Whenever you make an external call, your system automatically uses LCR to set up a
connection to a network operator that has been selected by the system administrator.
If you do not wish to use this preferred connection and want to select a network
operator yourself for each call (i. e. on a call-by-call basis), then before making the call,
select LCR off
(see also the LCR off menu in the section entitled "Selection" Menu in the Idle State
starting on page 37). This is only necessary if LCR has been configured for you in the
OpenCom 100 / Aastra 800. Consult your system administrator about this.
Note
Baby call and external call forwarding are not automatically routed via preferred con-
nections. In this case, if the network operator you wish to use is not the default oper-
ator, you must prefix the desired call number with the operator's code.
