Call in Substitution or with Signature
You can also place an external call in substitution or with signature.
This concerns the exceptional use of a third party set that is NOT
an IP H.323 Dialog 4425 or Dialog 4422, to place an external call,
just as if you were using your own extension.
The main advantage of this feature is that the call is charged to
your own extension. Another advantage is that on the substituted
third party set, you have all of your extension’s customary services,
most especially dialling discriminations relating to various external
numbers applicable for your extension.
This service is valid on a call-by-call basis. It is automatically cancelled
at the end of each call processed using this service.
To activate this substitution procedure from any extension (that is
other than an IP H.323 extension), after lifting the handset:
75
z
Dial the prefix “75”, granting access to the call in substitution
service.
STATION NO
z
Then dial your own extension number.
This is necessary in order to sign on to the third party set.
PASSWORD
z
Next, dial your user password.
By default, your user password is “1234”, however you may have
modified it. See also the “ Programming Your Extension’s Services ”
section. d
Hang up in order to terminate access to this service.
You may now proceed with placing your external call in substitution
from the previous extension.
After lifting the handset again:
NO TO CALL
z
Simply dial the desired external number.
You may do so according to any of the methods available on this
extension for dialling an external number. Your call is then
established normally.
Note: The prefix “75” is the one usually used to access the
call in substitution service. It may, however, have been
modified by your system administrator.
