Outgoing Calls, Busy/No-Answer
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.
To use this service when placing an external call:
*
Dial the “*” code to access to the DTMF end-to-end dialling
service.
Everything that is dialled thereafter is then directly transmitted to
the remote server.
Note: When you interact with the voice mail system, or the
automated attendant possibly integrated in your facility, the
aforementioned operations are not required. DTMF end-to-
end dialling is automatic. See also section “ Voice Mail
Services ” on page 73.
Ending Calls
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:
æ
Press.
Your extension returns to idle status.
