In all cases, this protection against the re-direction of your calls to
the automated attendant is never dependant upon any action on
your part.
Secret of Identity
When your facility is connected to the ISDN network, your identity
is usually transmitted to your external calling parties, and vice
versa.
According to the specific right assigned to your extension, it is
possible that your identity not be divulged to your external ISDN
network calling parties.
This is therefore systematically valid for all of your outgoing ISDN
network calls, without any specific action on your part.
Your identity is divulged, however, for your internal calls, and you
still receive the information concerning your external incoming
calling parties.
Account Codes
When a call is placed on the public ISDN network, the network
transmits the charges for the current call, which are then
accounted to a charge counter associated with your extension.
According to your working mode, you may wish to impute the cost
of your external calls to different accounts. Your telephone system
can do this through account codes that you simply enter when
placing outgoing external calls.
To establish an outgoing external call using an account code:
Z
First, dial the network access prefix adapted to this service.
Generally, this consists of a network access prefix that is reserved
for placing outgoing external calls that are subject to account
codes. Ask your system administrator for this prefix.
