Translate SI and PI - SIP to SS7
Feature F-5636 gives a user the ability to decide whether the screening
indicator, presentation indicator, or both will be passed through to the
SS7 IAM Calling Party number unchanged or passed through with overridden
values that are configured through the Advanced Originating Number Parameter
object. The feature is supported only when SIP Privacy is enabled and
a call is received by the IMG from the SIP network and is transmitted
to the SS7 network. Because the feature modifies the behavior of the IMG,
a field has been added that can disable or enable the new functionality.
The default setting in the ClientView GUI is Disable which forces the
IMG to interwork the parameters as it did before the feature was introduced.
Refer to the links below for more information regarding this feature.
