Feature Description

The Enhanced Generic Number Handling feature enables the Cisco PGW 2200 Softswitch to pass the Generic Number parameter present in a UK ISUP IAM message into the user field of the P-Asserted-ID header in a SIP INVITE message when the Number Qualifier field in the Generic Number is set to "intra-nw-use" (254 in the signaling). This feature introduces a new property called GenNumInclude. The GenNumInclude property enables or disables the feature as follows:

•When set to 1, the system maps the Generic Number in an IAM to the user field of the
P-ASSERTED-ID Header in a SIP INVITE.

•When set to 0, the system does not map the Generic Number to the user field of the
P-ASSERTED-ID Header in a SIP INVITE.

Note This feature is restricted to deployments in which the ISUP side is provisioned for the United Kingdom variant (ISUPV3_UK).

The Cisco PGW 2200 Softswitch performs this message conversion when it determines that it must set up a call between an ISUP network on the originating side and a SIP network on the destination side.

Prerequisites

The Cisco PGW 2200 Softswitch must be running Release 9.8(1) S10P10. Prerequisites for this release are documented in the Release Notes for the Cisco Media Gateway Controller Software Release 9.8(1) at:

Provisioning Examples

This section provides a provisioning example for this feature. Additional provisioning examples for the Cisco PGW 2200 Softswitch software are contained in Cisco PGW 2200 Softswitch Software Release 9.8 Provisioning Guide.

Provisioning Properties to Support Enhanced Generic Number Handling

The following sample MML command sequence provisions the Enhanced Generic Number Handling feature. When provisioned, the Cisco PGW 2200 Softswitch passes a Generic Number received in an IAM to the username of a P-Asserted-ID in a SIP INVITE. 

prov-ed:profile:name="sip-prof1",mapclitosipheader="3"

prov-ed:profile:name="sip-prof1",CliSelectionForCodeOfPractice3 ="2"

prov-ed:profile:name="sip-prof1",GenNumInclude="1".

prov-add:profile:NAME="sippro1",type="grprofile",cgpninclude="0" 

prov-ed:profile:name="sip-prof1",grprofile="sippro"

Software Changes for This Feature

•Properties

Properties

Provision the properties presented in this section to enable this feature on the
Cisco PGW 2200 Softswitch software. For information on other properties for the Cisco PGW 2200 Softswitch software, see Cisco PGW 2200 Softswitch Release 9 MML Command Reference.

Table 1 describes one existing property that you must provision for this feature and a new property introduced for this feature.

Table 1 Properties 

Property
Definition

mapclitosipheader (existing)

Indicates the mapping from ISUP CLI to the outgoing SIP message. Maps the calling party number to the P-Asserted ID in the privacy header value ID. If an additional calling party number is contained in the Generic Number field, the
Cisco PGW 2200 Softswitch maps it to the SIP From header.

Valid values: Integer (0-4)

•0—Map the CLI to the SIP From header.

•1—Map the CLI to Remote-Party-ID header, in addition to the SIP From header.

•2—Map the CLI to Remote-Party-ID header, in addition to the SIP From header only when the CLI presentation is allowed.

•3—Map the CLI to P-Asserted-ID header, in addition to the SIP From header.

Note Set this property to 3 to enable the Enhanced Generic Number Handling feature.

•4—Map the CLI to P-Asserted-ID header, in addition to the SIP From header, only when the CLI presentation is allowed.

Default: 0

Dynamically reconfigurable: yes.

This property was added in software Release 9.8(1).

Provisioning example to support the Enhanced Generic Number Handling feature: 

prov-ed:profile:name="sip-prof1",mapclitosipheader="3"

GenNumInclude (new)

Enables or disables the mapping of the Generic Number to the user field of a P-ASSERTED-ID Header in a SIP INVITE.

Valid Values:

•1—Map the Generic Number in IAM to the user field of the P-ASSERTED-ID in a SIP INVITE. (Generic Number Handling Enabled)

•0—Do not map the Generic Number to the user field of the P-ASSERTED-ID in a SIP INVITE. (Generic Number Handling Disabled)

Default Value: 0

Property Domain: SIP PROFILE

Protocol Family: SIP

Provisioning example: 

mml> prov-ed:profile:name="sip-prof1",GenNumInclude="1"

Note To enable the Generic Number Handling feature, provision the mapclitosipheader property to the value 3.
