Operations for Outgoing Calls

You may now proceed with placing your external call in substitution

from the previous extension.

After lifting the handset or in handsfree mode:

NO TO CALL

z

Simply dial the desired external number.

You may do so according to any of the methods available for

dialling an external number. Your call is then established normally.

Note: This service is accessible from any extension other

than an IP H.323 Dialog 4425 or Dialog 4422 extension.

Rather selecting the “SIGN_ON” dynamic function key,

simply dial the “75” prefix. This prefix may, however, have

been modified by your system administrator.

DTMF End-to-End Dialling

At times, you may need to call external servers, such as a reservation

centre server, when you are required to communicate interactively

through the online transmission of various dialling codes.
Your extension makes this option available to you through the

DTMF end-to-end dialling service. With this service, you can

directly exchange dialling codes with a remote server, without

your dialling being interpreted by your local facility.
This is processed through the exchange of DTMF codes, from

which the service’s name is derived. You can hear the codes in

the form of tones in your telephone.
To use this service when placing an external call:

DTMF

Press the dynamic function key shown on the left to activate
the service.

Everything that is dialled thereafter is then directly transmitted to

the remote server.
