Operations for Outgoing Calls
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 ex-
change 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.
To use this service when placing an external call:
*
z
Dial the “*” code, granting access to the DTMF end-to-end
dialling service.
Everything that is dialled thereafter is then directly transmitted to
the remote server.
Notes:
The “*” code is the suffix usually used to access the DTMF
end-to-end dialling service. It may, however, have been
modified by your system administrator.
When you interact with the voice mail system, or the auto-
mated attendant possibly integrated in your facility, the
afore-
mentioned operations are not required. DTMF end-to-end
dialling is automatic. See also the “ Voice Mail Services ”
section.
Ending a Call
You may, at any time, end an ongoing call, or an outgoing call that
is being established.
This is done in the same way as with an incoming call:
d
Hang up the handset.
Your extension returns to idle status.
