Suppression of Redirecting Number and Information Feature Module
Feature Description
Feature Description
When a call that is made from the ISUP (ETS_300_356) to the Session Initiation Protocol (SIP) is
redirected to the ISUP (ETS_300_356), the following information is sent in Initial Address Messages
(IAM) or Address Complete Messages (ACM):
•
Original Called Number in an IAM
•
Redirecting Number in an IAM
•
Call Diversion Information in an ACM
•
Redirection Information in an IAM
•
Redirection Number in an ACM
The Suppression of Redirecting Number and Information feature enables the optional suppression of the
above parameters in IAMs and ACMs. In incoming messages, these parameters are parsed and processed
for all existing call logics. The decision about suppression is taken when encoding or packing the ISUP
messages in the outgoing direction of the Cisco PGW 2200 Softswitch. The ISUP trunk group properties
are used to configure the suppression.
Note
By default, all these parameters can be sent to the destination, which is consistent with the current
behavior of Cisco PGW 2200 Softswitch.
Benefits
This feature provides the following benefit:
Suppression of certain ISUP parameters in the IAMs or ACMs while using the
Cisco PGW 2200 Softswitch ISUP variant ETSI V2 (ETS_300_356).
Prerequisites
The Cisco PGW 2200 Softswitch must be running Cisco PGW 2200 Softswitch software Release 9.8(1).

Provisioning Tasks
This section describes the provisioning tasks for this feature.
To use this feature, perform the following main tasks:
•
Suppress the Original Called Number in an IAM
•
Suppress the Redirecting Number in an IAM
•
Suppress Call Diversion Information in an ACM
•
Suppress Redirection Information in an IAM
•
Suppress the Redirection Number in an ACM
Suppress the Original Called Number in an IAM
The property ocnInclude indicates whether or not to include the Original Called Number in an IAM.
Valid values are:
•
0—Does not allow the parameter OCN to be inserted into a message.
•
1—Allows the parameter OCN to be inserted into a message. This is the default value.
To suppress the Original Called Number in an IAM, use the property ocnInclude with the following
command:
prov-ed:sigsvcprop:name="ss7path1",ocnInclude="0"

Provisioning Tasks
Suppress the Redirecting Number in an IAM
The property rnInclude indicates whether or not to include the Redirecting Number in an IAM. Valid
values are:
•
0—Does not allow the parameter RN to be inserted into a message.
•
1—Allow the parameter RN to be inserted into a message. This is the default value.
To suppress the Redirecting Number in an IAM, use the property rnInclude with the following command:
prov-ed:sigsvcprop:name="ss7path1",rnInclude="0"
Suppress Call Diversion Information in an ACM
The property DiversionInfoInclude indicates whether or not to include call diversion information in an
ACM. Valid values are:
•
0—Does not allow call diversion information to be inserted into a message.
•
1—Allow call diversion information to be inserted into a message. This is the default value.
To suppress call diversion information in an ACM, use the property DiversionInfoInclude with the
following command:
prov-ed:sigsvcprop:name="ss7path1",DiversionInfoInclude="0"
Suppress Redirection Information in an IAM
The property redirInfoInclude indicates whether or not to include redirection information in an IAM.
Valid values are:
•
0—Does not allow redirection information to be inserted into a message.
•
1—Allow redirection information to be inserted into a message. This is the default value.
To suppress redirection information in an IAM, use the property redirInfoInclude with the following
command:
prov-ed:sigsvcprop:name="ss7path1",redirInfoInclude="0"
Suppress the Redirection Number in an ACM
The property GenerateRedirectionNumber indicates whether or not to include the Redirection Number
in an ACM. Valid values are:
•
0—Does not allow the Redirection Number to be inserted into a message.
•
1—Allow the Redirection Number to be inserted into a message. This is the default value.
