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, 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. 75
