SIP-I Protocol Feature Module Feature Overview
Feature Overview
SIP-I (SIP with encapsulated ISUP) is an ITU-defined SIP extension which allows IP networks to provide services that are supported by ISUP networks, for example, malicious call identification. The feature allows the Cisco PGW 2200 Softswitch to interwork between SIP-I and ISUP, and also to interwork between SIP-I and other protocols such as SIP, H.323, PRI, and QSIG. Where PSTN services are required in IP networks, SIP trunks with SIP-I support can be the preferred method for supplying these services, because the ISUP content is encapsulated in SIP message headers.
The SIP-I Protocol feature is useful in a next-generation network (NGN) emulation model, where the Cisco PGW 2200 Softswitch, working with the Cisco BTS 10200 Class 5 softswitch in a SIP solution, communicates with other NGNs using SIP-I. This new feature is also useful for bridging existing PSTN networks without TDM interconnections being required.
This feature introduces a SIP-I interface license. For more information about the SIP-I interface license on the Cisco PGW 2200 Softswitch, see the Licensing Features for the Cisco PGW 2200 Softswitch at http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/feature/module/9.7_3_/FlexLM.html See the following lists of ISUP services interworking and transmitting with SIP-I on the Cisco PGW 2200 Softswitch.

Benefits
The feature allows service providers to offer a complete VoIP interconnection which can handle PSTN services that the traditional TDM ISUP interconnection supports. Among all the IP interconnection forms (such as SIP, SIP-I, and H.323), SIP-I interconnections can be the destination of choice if service providers require PSTN service interworking.
The Cisco PGW 2200 Softswitch supports ITU, ANSI, German, UK, Finnish, and Russian ISUP encapsulated in SIP-I messages, which allows a high degree of interworking for many services across a SIP-I configured link.You can provision the closest base or the closest country-specific SIP-I variant if you are using SIP-I for other ISUP variants. The service interoperability level between SIP-I and other protocols such as SIP, H.323, PRI, and QSIG, is lower than the interoperability level between SIP-I and ISUP, but is nearly equivalent to the interoperability level between those protocols and ISUP today.
Prerequisites

Provisioning an Incoming SIP Trunk Group
SIP-I Version Name and ISUP Variant Mapping
The Cisco PGW 2200 Softswitch uses the version subparameter in the Content-Type header of a SIP-I INVITE message to identify SIP-I variants. In order to specify the SIP-I variants supported on the incoming trunk groups, you can add a file, sipIVersion.dat, through MML commands, and associate it with the incoming trunk group SIP profiles. The following provisioning example is applicable to specific networks.
Add Mapping Entries in sipIVersion.dat File
prov-add:sipiversion:profilename="BT",version="X-UKISUP",mdo="ISUPV3_UK_SIPI" prov-add:sipiversion:profilename="BT",version="etsi356",mdo="ISUPV3_UK_SIPI" prov-add:sipiversion:profilename="BT",version="itu-t92+",mdo="Q761_99VER_BASE_SIPI" prov-add:sipiversion:profilename="US",version="itu-t92+",mdo="Q761_99VER_BASE_SIPI" prov-add:sipiversion:profilename="US",version="ansi00",mdo="ANSISS7_STANDARD_SIPI" prov-add:sipiversion:profilename="GERMAN",version="isupv2-german",mdo="ISUPV2_GERMAN_SIPI" prov-add:sipiversion:profilename="FINNISH",version="isupv2-finnish96",mdo="ISUPV2_FINNISH9 6_SIPI" prov-add:sipiversion:profilename="RUSSIAN",version="Q761_97VER_RUSS",mdo="Q761_97VER_RUSS_ SIPI"

Add a SIP Profile
prov-add:profile:name="sipi-in",type="SIPPROFILE",sipmimebodysupport="4"
Note To support both SIP and SIP-I on the incoming trunk group and support SIP-I on the outgoing trunk group, the Cisco PGW 2200 Softswitch requires the property sipMimeBodySupport to be set to 4.
For detailed property information, see the “Properties” section on page 18.
Attach the SIP-I Mapping Profile to the SIP Profile
prov-ed:profile:name="sipi-in",sipiingressversionmap="BT"
Note You attach the SIP-I mapping profile BT to the SIP profile sipi-in by the preceding command. According to the preceding SIP-I mapping table, the incoming trunk group supports three SIP-I versions of the SIP-I mapping profile BT in Content-Type of the SIP-I messages.
(Optional) Attach the ISUP TMR Profile to the SIP Profile
prov-add:profile:name="isup01",type="ISUPTMRPROFILE",t6="120000", variant="etsi356",t2="180000",t9="60000",t33="12000",validation="OFF" prov-ed:profile:name="sipi-in",isuptmrprofile="isup01"
Attach the SIP Profile to the Trunk Group
prov-add:trnkgrpprof:name=”2000”,profile=”sipi-in”
Incoming SIP-I Message Processing
Figure 4 shows how Cisco PGW 2200 Softswitch starts a SIP-I variant to process a specific SIP-I message on the incoming SIP trunk group based on your provisioning. From the source IP of the incoming SIP-I message, Cisco PGW 2200 Softswitch selects the trunk group 2000. With the selected trunk group, Cisco PGW 2200 Softswitch selects a SIP-I mapping profile according to the value of the property sipMimeBodaySupport and the property SipIIngressVersionMap. Based on the selected SIP-I mapping profile and the Content-Type field in the SIP-I message, Cisco PGW 2200 Softswitch starts ISUPV3_UK_SIPI as the SIP-I variant to process the incoming SIP-I message.

prov-ed:profile:name="sipi-out",sipiegresshandling="2"
Note To always add “handling=required” to the Content-Disposition header of the INVITE message, the Cisco PGW 2200 Softswitch requires the property SipIEgressHandling to be set to 2.
For detailed property information, see “Properties” section on page 18.
(Optional) Provision the SipICANCELEncapREL Property on the SIP Profile
To make the encapsulated REL message required in the SIP-I CANCEL message, you need to provision the SipICANCELEncapREL property as follows:
prov-ed:profile:name="sipi-out",sipicancelencaprel="1"
(Optional) Attach the ISUP TMR Profile to the SIP Profile
prov-add:profile:name="isup02",type="ISUPTMRPROFILE",t6="120000",variant="isupv2-german",t 2="180000",t9="60000",t33="12000",validation="OFF"

Attach the SIP Profile to the Trunk Group
prov-add:trnkgrpprof:name="3000",profile="sipi-out"
Outgoing SIP-I Message Processing
Figure 5 shows how Cisco PGW 2200 Softswitch transforms the incoming ISUP messages to the outgoing SIP-I messages if the route preference is enabled. The Cisco PGW 2200 Softswitch selects a route from the route analysis after a German ISUP initial address message (IAM) comes in. If the route preference is enabled, Cisco PGW 2200 Softswitch selects the trunk group 3000 based on the trunk group property SipIEgressMDO. The other trunk group properties, sipMimeBodySupport,
SipIEgressHandling, and SipIEgressISUPVersion, determine the content of SIP-I header fields in the outgoing SIP-I messages.
Note If the route preference is not enabled, Cisco PGW 2200 Softswitch selects an outgoing trunk group in the route as the result of the route analysis. The trunk group property SipIEgressHandling provisioned on this trunk group determines the content of SIP-I header fields in the outgoing SIP-I messages.

Enabling the Route Preference
numan-add:resulttable:custgrpid="1000",setname="set-7",name="rp",resulttype="SIPI_CONTROL" ,dw1="1"
Note SIPI_CONTROL is a new result type introduced in this feature. To enable the SIP-I route preference, the Cisco PGW 2200 Softswitch requires the dw1 to be set to 1.
It is possible to configure the Cisco PGW 2200 Softswitch so that, for calls between ISUP and SIP trunks with SIP-I supported, the Cisco PGW 2200 Softswitch tries to route the calls using the SIP trunk on which the corresponding SIP-I variant is available to match the ISUP trunk. Use the SIPI_CONTROL result type in dial plans to achieve this.
For detailed information on this result type, see the “Result Type Definitions” section on page 26. For detailed information on the dial plan, see the Cisco PGW 2200 Softswitch Release 9.8 Dial Plan Guide at http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/dial_plan/guide/dplan.html.
Additional Provisioning for Finnish SIP-I
Finnish SIP-I has some specific message requirements which require additional provisioning: • Add Meter Pulse Message Support, page 12
• Give ISUP Encapsulation Priority over SIP Headers, page 12 • Map the Cause Code, page 12
• Stop the Hop Counter and Satellite Indicator From Increasing, page 12 • Set Calling Party Number (CgPN) APRI to Presentation Restricted, page 13

SIP-I Protocol Feature Module Provisioning Tasks
Add Meter Pulse Message Support
Currently the Cisco PGW 2200 Softswitch supports meter pulse message (MPM) which is required in Finnish ISUP. Finnish SIP-I encapsulates MPMs in INFO messages in order to interwork this Finnish ISUP service among service providers. For details on provisioning MPM support for Finnish ISUP on the Cisco PGW 2200 Softswitch, see the section, Provisioning Tasks, of the feature guide Meter Pulse Messages Support at
http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/feature/module/9.5_1_/FMmpm.html.
Give ISUP Encapsulation Priority over SIP Headers
Finnish SIP-I requires that within an incoming SIP-I message, the parameters in the encapsulated ISUP message has higher priority over the ones in the SIP header when the device decodes the SIP-I message. To achieve this on the Cisco PGW 2200 Softswitch, you need to provision the SipICLICOLPreference property for the SIP profile used for Finnish SIP-I.
prov-ed:profile:name="sipi-in",sipiclicolpreference="1"
Note To make encapsulated ISUP content has higher priority over SIP headers in the decoding of incoming SIP-I messages, set the SipICLICOLPreference to 1.
For detailed property information, see “Properties” section on page 18.
Map the Cause Code
According to Ficora GFI 0301: Guidelines for Implementation ISUP-SIP Interworking Profile C (Finland ISUP), Finnish SIP-I map the cause code 24 to the SIP status code 503 Service Unavailable. You need to manually map the cause code 24 (internal cause value IC_REJECTED_BY_FEATURE (169) by default) to 503 Service Unavailable (internal cause value IC_SERVICE_UNAVAIL(209) by default):
numan-add:resultset:custgrpid="1111",name="cause-set-1"
numan-add:cause:custgrpid="1111",setname="cause-set-1",causevalue= 169
numan-add:resulttable:custgrpid="1111",setname"cause-set-1",name="cause-tbl-1",resulttype= "CAUSE",dw1=209
Note For details on the ISUP cause codes and the internal cause codes on the Cisco PGW 2200 Softswitch, see Appendix B, Cause and Location Codes in Cisco PGW 2200 Softswitch Release 9.8 Dial Plan Guide at the following URL.
http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/dial_plan/guide/dplan.html
Stop the Hop Counter and Satellite Indicator From Increasing
The hop counter has no value change for an ISUP to Finnish SIP-I call. There is no satellite circuit in the connection according to the Ficora GFI 0301. If you have provisioned the CircHopCount and the SatelliteInd properties to other values, you need to set them to default values in the common profile:
prov-add:profile:name="sipicommon",type="COMMONPROFILE",circhopcount="0" prov-ed:profile:name="sipicommon",satelliteind="0"

Unsupported SIP-I Call
Description
This alarm is triggered when the Cisco PGW 2200 Softswitch rejects an unsupported SIP-I call.
Severity
Informational (non-service affecting)
Cause
The Cisco PGW 2200 Softswitch raises the alarm in any one of the three following cases:
• If the property sipMimeBodySupport is set to 3 (only SIP-I supported on the incoming trunk group) and the Content-Disposition header in the incoming SIP-I message contains “handling=required”, the Cisco PGW 2200 Softswitch cannot find any matched SIP-I mapping profile or version entry in the configuration.
• The property sipMimeBodySupport is set to 0 (only SIP supported on the incoming trunk group), and the Content-Disposition header in the incoming SIP-I message contains “handling=required”. • If the property sipMimeBodySupport is set to 3 (only SIP-I supported on the incoming trunk group),
the Cisco PGW 2200 Softswitch receives a SIP INVITE message.
Type
Processing error alarm
Action
Perform the following steps:
1. Check the sipMimeBodySupport property value to make sure that SIP/SIP-I call is allowed on the incoming trunk group.
2. Check the SipIIngressVersionMAP property value on the incoming SIP trunk group.
3. Use the following command to see whether the Cisco PGW 2200 Softswitch selects the correct SIP-I variant:
prov-rtrv:sipiversion:profilename="SIP-I mapping profile name",version="SIP-I version in Content-Type"

– 5 (Q1912.5 supported) = The Cisco PGW 2200 Softswitch sends a 180 Ringing with SDP.
• If the terminating side can play the remote ringback tone but the alerting signaling does not include the Inbandinfo indicator, you can provision the support183 property:
– 4 (always send 183) = The Cisco PGW 2200 Softswitch sends a 183 Session Progress with SDP.
– 5 (Q1912.5 supported) = The Cisco PGW 2200 Softswitch sends a 180 Ringing with SDP.
Action Description
Step 1 Check the MPM provisioning on the Cisco PGW 2200 Softs witch
For details on provisioning MPM support for Finnish ISUP on the Cisco PGW 2200 Softswitch, see the section, Provisioning Tasks, of the feature guide Meter Pulse Messages Support at
http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/feature/module/ 9.5_1_/FMmpm.html.
Step 2 Check the property SipICLICOLPreference
For Finnish SIP-I, encapsulated ISUP takes precedence over SIP headers. Make sure the SipICLICOLPreference property is set to 1.

Mapping Details
This section contains additional information which may be useful for you to understand specific mapping details of parameters. The heavy vertical line in the tables indicates where the mapping takes place. Different combinations of input message parameters and the Cisco PGW 2200 Softswitch properties on the left of the heavy vertical line have corresponding mapping results on the right. These tables are not limited to SIP and ISUP mapping.
Table 5 describes the mapping from SIP header fields to ISUP message parameters under control of the property InhibitSipFromMapping. Table 6 describes the mapping from the address complete message (ACM) to 180 Ringing /183 Session Progress under control of the property Support183. Table 7 describes the mapping from the call progress message (CPG) to 180 Ringing /183 Session Progress under control of the property Support183.

1. CgPN = calling party number.
2. GN = generic number (Q1912.5/EN 383 001, ND 1017 only). 3. GA = generic address (T1.679 only).
4. PN = presentation number (ND1017 only).
5. For SIP-URI in the P-Asserted-Identity or the From header field, if the field userinfo is E164 number with parameter “user=phone” or the field userinfo is E164 number with respectSipUriUserParm value set to 0, the Cisco PGW 2200 Softswitch treats the SIP-URI as E164 format.
