Feature Overview
This feature provides support on the Cisco MGC of the ISDN User Part (ISUP)-to-Session Initiation
Protocol (SIP) mapping of calling line identity (CLI) to the SIP Remote Party ID header or the
P-Asserted ID header. It also updates the generic handling of the SIP-to-ISUP and ISUP-to-SIP mapping
of CLI, generic number (GN), and redirecting number (RN).

SIP Remote Party ID and P-Asserted Support
Feature Overview
Note
In this document, the term CLI, calling party number, and CgPN are used to refer to the directory number
that is dialed to terminate a call to a phone.
This feature provides the following:
•
Support for the ISUP-to-SIP mapping of CLI to the From header, SIP Remote Party ID, or
P-Asserted ID.
•
An update of the generic handling of the SIP-to-ISUP and ISUP-to-SIP mapping of calling line
identity.
•
An update of ITU ISUPs generic number (containing the additional calling number), and redirecting
number.
Benefits
This feature provides the benefits described in the following paragraphs.
Comprehensive Mapping to All the Defined Containers for Calling Party Number(s)
The calling party number was stored in the SIP From header.in the initial SIP RFC 2543. Later Remote
Party ID was added, and finally P-Asserted was added. This feature allows use of any of the possible
headers where the calling number can be stored.
ISUP-to-SIP Mapping
Although ISUP-to-SIP is the primary focus, mapping also works for calls from Q.931, QSIG, DPNSS,
and H.323 to SIP. The MGC 2200 supports mapping the CLI into the SIP From header, and optionally
into the SIP Remote Party ID leader or the P-Asserted-ID on an outgoing SIP trunk group basis.

Retrieving Provisioning Data, page 6
For more detailed information about provisioning your Cisco MGC, refer to the Cisco Media Gateway
Controller Software Release 9 Provisioning Guide.
Starting a Provisioning Session
You might need to start a provisioning session as part of your system operations. To do this, log in to the
active Cisco MGC, start an MML session, and enter the following command:
prov-sta::srcver=”curr_ver”,dstver=”mod_ver”
Where:
•
curr_ver—The name of the current configuration version. In place of the name of the current
configuration version, you can also enter:
– new—A new default session configuration; no existing source configuration is available.
– active—Selects the active configuration as the source for configuration changes.
Note
•
If you do not know the name of your current configuration session, you can use the procedure
described in the Retrieving Data on the Current Provisioning Session, page 7.
mod_ver—A new configuration version name that contains your provisioning changes.
For example, to use a configuration version called ver1 as the basis for a version to be called ver2, you
would enter the following command:
prov-sta::srcver=“ver1”,dstver=“ver2”
Note
The InhibitSipFromMapping, MapCLItoSipHeader, and MapRNtoSipHeader properties could not be
provisioned from an old configuration version before software Release 9.5(2) Patch S039 P032. For
example, if ver1 was a previous configuration generated before the new properties were introduced, you
could not provision the new properties by the MML command prov-sta::srcver=“ver1”,dstver=“ver2”.
Once a provisioning session is underway, you may use the prov-add, prov-ed, or prov-dlt MML
commands to add, modify, and delete components on your system. This document describes how to
provision this feature. For more information on provisioning other components on your Cisco MGC,
refer to the Cisco Media Gateway Controller Software Release 9 Provisioning Guide.
There are two ways to close your provisioning session: saving and activating your provisioning changes,
as described in the “Saving and Activating Your Provisioning Changes” section on page 4, or ending
your provisioning session without saving and activating your changes, as described in the “Ending a
Provisioning Session Without Activating Your Changes” section on page 5.
Saving and Activating Your Provisioning Changes
When you have completed making provisioning changes in your session, you must enter a command to
save and activate your changes. There are two different provisioning MML commands that do this:
prov-cpy and prov-dply.
Cisco MGC Software Release 9.5(2)
4
SIP Remote Party ID and P-Asserted Support
Provisioning Tasks
Caution
Using the prov-cpy or prov-dply MML command can severely impact your system’s call processing
performance, depending on the extent of your provisioning changes. We recommend that these
commands be issued during a maintenance window when traffic is minimal.
Use the prov-cpy MML command to save and activate your changes on simplex Cisco MGC
(single-host) systems.
Note
When you enter the prov-cpy command, your provisioning session is automatically ended. If you want
to make additional provisioning changes, you must start a new provisioning session as described in the
“Starting a Provisioning Session” section on page 4.
Caution
Do not use the prov-cpy command to save and activate your changes on a continuous-service
Cisco MGC system (one with active and standby hosts). Saving and activating with prov-cpy on such a
system would require use of the prov-sync MML command to synchronize the provisioning data on the
active and standby hosts. The system does not indicate when the synchronization process fails, which
would create problems when a switchover operation occurs.
Use the prov-dply MML command to save and activate your changes on the active and standby
Cisco MGCs in a continuous-service system. Do not use his command on a Cisco MGC in a simplex
configuration.
Note
When you enter the prov-dply command, your provisioning session is automatically ended, unless an
error occurs during execution. If you want to make additional provisioning changes, you must start a new
provisioning session, as described in the “Starting a Provisioning Session” section on page 4.
Ending a Provisioning Session Without Activating Your Changes
If you want to end a provisioning session without saving and activating the changes you have entered,
enter the prov-stp MML command. This command ends your current provisioning session and your
changes are not entered.

Retrieving Provisioning Data
You can use the prov-rtrv MML command to retrieve information about your current provisioning
settings. The ways you can use this command to retrieve provisioning data are described in the following
sections:
•
Retrieving Data for an Individual Component, page 6
•
Retrieving Data for All Components, page 6
•
Retrieving Data for All Components of a Particular Type, page 6
•
Retrieving Data on the Current Provisioning Session, page 7
•
Retrieving Data on Supported Signaling Protocols, page 7
Retrieving Data for an Individual Component
You can retrieve provisioning data on any individual component in your system. To do this, log in to the
active Cisco MGC, start an MML session, and enter the following command:
prov-rtrv:component:name=MML_name
Where:
•
component—The MML component type associated with the desired component. You can find a
complete list of MML component types in the Cisco Media Gateway Controller Software Release 9
Provisioning Guide.
•
MML_name—The MML name for the desired component. You can determine the MML names for
the various components using the prov-rtrv:all MML command.
For example, to view the provisioning data for an SS7 signaling service called ss7svc1, you would enter
the following command:
prov-rtrv:ss7path:name="ss7svc1"
The response to the retrieve command depends on the component type associated with the desired
component. For example, to view the properties for an SUA routing key called suakey1, you would enter
the following command:
prov-rtrv:suakey:name="suakey1"
Retrieving Data for All Components
You can retrieve data on all of the components provisioned on your system. To do this, log in to the active
Cisco MGC, start an MML session, and enter the following command:
prov-rtrv:all
Retrieving Data for All Components of a Particular Type
You can retrieve provisioning data on all components of a particular type on your system. To do this, log
in to the active Cisco MGC, start an MML session, and enter the following command:
prov-rtrv:component:“all”
Where component is the MML component type associated with the desired component group. You can
find a complete list of MML component types in the Cisco Media Gateway Controller Software
Release 9 Provisioning Guide.

SIP Remote Party ID and P-Asserted Support
Provisioning Examples
Provisioning Scenario 1
In Scenario 1 the calling party number maps to the SIP From header and ignores the ACgPN if it is
presented in the ISUP message. If Presentation in the calling party number is restricted, the calling party
number maps to the SIP From header as “Anonymous <sip:[email protected]>”.
mml> prov-ed:sigsvcprop:name="sip-path",mapclitosipheader="0"
Note
The default value of mapclitosipheader is 0. If this property is not modified, or you are
provisioning from “new”, this command is not needed.
mml> prov-add:PROFILE:NAME="sippro",TYPE="grprofile",cgpninclude="0"
mml> prov-add:TRNKGRPPROF:name="5600",grprofile="sippro"
Note
5600 is the name of the IP outgoing trunk.
Scenario 2
In Scenario 2, the calling party number maps to the SIP From header and ignores the ACgPN if it is
presented in the ISUP message. If Presentation in the calling party number is restricted, map the calling
party number to the SIP From header as “Anonymous <sip:CGPN@PGW_HOST>”.
mml> prov-ed:sigsvcprop:name="sip-path",mapclitosipheader="0"
Note
The default value of mapclitosipheader is 0. If this property is not modified, or you are
provisioning from “new”, this command is not needed.
mml> prov-add:PROFILE:NAME="sippro",TYPE="grprofile",cgpninclude="1"
The default value of cgpninclude is 1.
mml> prov-add:TRNKGRPPROF:name="5600",grprofile="sippro"
Note
5600 is the name of the SIP outgoing trunk.
Scenario 3
In Scenario 3, the calling party number maps to the SIP From header and the P-Asserted ID header. If
ACgPN is presented and Presentation is allowed, overwrite the SIP From header with the ACgPN. If
Presentation is restricted in ACgPN, overwrite the SIP From header as “Anonymous
<sip:[email protected]>”. If Presentation is NA in ACgPN, do not overwrite the SIP
From header.
mml> prov-ed:sigsvcprop:name="sip-path",mapclitosipheader="3"
mml> prov-add:PROFILE:NAME="sippro",TYPE="grprofile",cgpninclude="0"
mml> prov-add:TRNKGRPPROF:name="5600",grprofile="sippro"

Property
Definition
MapCLItoSipHeader
Determines the mappings from the ISUP calling party number
to the outgoing SIP message. Valid range: 0 through 4.
Valid Values: 0—The calling party number is put in the
outgoing SIP From header if number presentation is allowed. If
the calling party number presentation is restricted, then the SIP
outgoing From header is also controlled by the cgpnInclude
property.
•
If cgpnInclude = 0, and the SIP network is untrusted, the
From header has SIP URI as: Anonymous
<sip:[email protected]>
•
If cgpnInclude = 1, and the SIP network is trusted, and
honors the anonymous setting by not passing the CLI to the
SIP end point, the From header has URI as Anonymous
<sip:CGPN@PGW_HOST>
1—The calling party number is mapped to the remote party ID,
with screen and privacy values. If an additional calling party
number is present in the generic number, it is mapped to the SIP
From header.
2—Map the calling party number to the Remote-Party-ID
header only when the calling party number presentation is
allowed. For handling the additional calling party number in the
generic number, the operation is the same as for a value of 1.
3—The calling party number is mapped to the P-Asserted ID,
with privacy header value ID, if necessary. If an additional
calling party number is present in the generic number, it is
mapped to the SIP From header.
Note
If the calling party number presentation is allowed,
there is no privacy header. If the calling party number
presentation is restricted, there is a privacy header with
a value ID.
4—Map the calling party number to the P-Asserted ID header
only when the calling party number presentation is allowed. For
handling the additional calling party number in the generic
number, the operation is the same as for a value of 3.
Default Value: 0

SIP Remote Party ID and P-Asserted Support
Reference Information
Mapping from SIP to ITU ISUP
For mapping information from a SIP-to-ITU ISUP call to the MGC, which is sent out on another
protocol, refer to Table 7. Even though this mapping functionality exists on the PGW, the SIP Remote
Party ID and P-Asserted Support feature provides the ability to set the InhibitSipFromMapping flag per
sigPath. If a From header is received from the SIP trunk and the flag is set to 1, then no CLI information
is sent.
When the Diversion header is present, it is mapped to the Redirecting number. Redirection information
is included in the ISUP message with a default value.
Note
When a diversion header with a “counter=x” value greater than 5 is mapped to the ISUP redirecting
counter, the value is set to 5 (RC=5).
The GN presentation indicator is the same as the CgPN PI as specified in Q.1912.5.
The SI for GN is always set to be UPNV (user provided, not verified) as specified in Q.1912.5.
The privacy header supports “id” and “user”.

SIP Remote Party ID and P-Asserted Support
Reference Information
Remote-Party-ID Mapping of Screening Indicator
If the rpi-token rpi = screen is included with the value of screen = no, then the CLI Screening indicator
is set to UPNV.
If the rpi-token rpi = screen is included with the value of screen = yes, then the CLI Screening indicator
is set to NP.
If the rpi-token rpi = screen is not included, then the CLI screening indicator can be set to UPNV.
