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

Figure 1 shows how service providers interwork the ISUP services using this SIP-I Protocol feature. In this figure, PGW B interconnects different ISUP variants and other protocols like ISDN, DPNSS, and EISUP on the SIP trunk with SIP-I support.
Figure 1 Interworking Between Service Providers with SIP-I
Figure 2 shows the SIP-I being used on multiple incoming SIP trunk groups. In this figure, Cisco PGW 2200 Softswitches interwork ISUP variants, ISDN, SIP, HSI (EISUP), DPNSS, and EISUP using multiple incoming SIP trunk groups on which different SIP-I versions are provisioned. PGW A interworks TDM, SIP, and H.323 protocols to SIP-I. PGW B interconnects SIP-I variants to the TDM, SIP, and H.323 protocols on multiple incoming SIP trunk groups with SIP-I support.
Figure 2 SIP-I Used on Multiple Incoming SIP Trunk Groups
Figure 3 shows the SIP-I being used on a single incoming SIP trunk group. In this figure, Cisco PGW 2200 Softswitches interwork ISUP variants, ISDN, SIP, HSI (EISUP), DPNSS, and EISUP using a single incoming SIP trunk group which has SIP-I support. This single incoming SIP trunk group of PGW B dynamically adapts to the incoming SIP-I message version.

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
The Cisco PGW 2200 Softswitch must be running Cisco PGW 2200 Softswitch software Release 9.8(1). Prerequisites for this release can be found in the Release Notes for Cisco PGW 2200 Softswitch Release 9.8(1) at

Additional Provisioning for Finnish SIP-I
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"The commands listed in the preceding example generate the following SIP-I mapping table.
Edit a Mapping Entry
prov-ed:sipiversion:profilename="BT",version="etsi356",mdo="ISUPV3_UK_SIPI"Retrieve a Mapping Entry
prov-rtrv:sipiversion:profilename="BT",version="etsi356"Delete a Mapping Entry
prov-dlt:sipiversion:profilename="BT",version="etsi356"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.
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.
Figure 4 Processing SIP-I Messages on the Incoming SIP Trunk Group
Provisioning an Outgoing SIP Trunk Group
Add a SIP Profile
prov-add:profile:name="sipi-out",type="SIPPROFILE",sipmimebodaysupport="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.
Provision the SIP-I Version on the SIP Profile
prov-ed:profile:name="sipi-out",sipiegressisupversion="isupv2-german"Provision the SIP-I Variant on the SIP Profile
prov-ed:profile:name="sipi-out",sipiegressmdo="ISUPV2_GERMAN_SIPI"Provision the Handling Property on the SIP Profile
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.
(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"prov-ed:profile:name="sipi-out",isuptmrprofile="isup02"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.
Figure 5 Processing SIP-I Messages on the Outgoing SIP Trunk Group
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. 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
•
Give ISUP Encapsulation Priority over SIP Headers
•
Stop the Hop Counter and Satellite Indicator From Increasing
•
Set Calling Party Number (CgPN) APRI to Presentation Restricted
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.
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= 169numan-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"prov-ed:profile:name="sipi-in",commonprofile="sipicommon" (using Finnish SIP-I on incoming trunks)orprov-ed:profile:name="sipi-out",commonprofile="sipicommon"(using Finnish SIP-I on outgoing trunks)Set Calling Party Number (CgPN) APRI to Presentation Restricted
Finnish SIP-I requires the CgPN APRI be set to presentation restricted.

http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/system/message/errmsg.html.
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"Properties
The properties identified in this section are used for the SIP-I Protocol feature. After confirming which SIP-I protocol standard you are following (see the "Supported Standards, MIBs, and RFCs" section), you can provision these properties according to that specific SIP-I protocol.

Troubleshooting the Feature
This section describes troubleshooting procedures for this feature:
•
Incoming SIP-I calls fail.
Action DescriptionStep 1
Check the property sipMimeBodySupport on the incoming trunk group.
The Cisco PGW 2200 Softswitch requires this property to be set to 3 or 4 in order to support SIP-I on the incoming trunk group.
For property details, see Properties.
Step 2
Check the SIP-I interface license.
Use the MML command, rtrv-lics:all, to check if the SIP-I license is available. The following example gives you an example of using this command to check the SIP-I license.
mml> rtrv-lics:all
The following system output is truncated. The bottom line indicates that the SIP-I interface license is available.

Step 3
Check the property SipIIngressVersionMap on the incoming trunk
The Cisco PGW 2200 Softswitch requires this property to be set to the desired SIP-I mapping profile on the incoming trunk group.
See Provisioning Tasks.
Step 4
Check the entry of that desired SIP-I mapping profile in sipIVersion.dat.
Check if entry of that desired SIP-I mapping profile is correctly provisioned in sipIVersion.dat.
1.
Check if the SIP-I version field of that entry matches the version subparameter in the Content-Type in the incoming SIP-I INVITE message.
2.
Check if the SIP-I variant field of that entry is correctly provisioned using the following command:
prov-rtrv:sipiversion:profilename="BT",version="etsi 356"For details on how to add, edit, and delete records in the sipIVersion.dat, see Provisioning Tasks.
•
Outgoing SIP-I calls fail.
Action DescriptionStep 1
Check the property sipMimeBodySupport on the outgoing trunk group.
The Cisco PGW 2200 Softswitch requires this property to be set to 3 or 4 in order to support SIP on the outgoing trunk group. For property details, see the "Properties" section.
Step 2
Check the SIP-I interface license.
See Step 2 in the previous troubleshooting procedure for failed incoming SIP-I calls.
Step 3
Check the Content-Disposition parameter in the outgoing SIP-I INVITE message.
If it is "handling=optional", change the SipIEgressHandling property on the outgoing trunk group to 2. See the "Provisioning Tasks" section.
Step 4
Check the SIP-I version defined in SipIEgressISUPVersion property.
Check if the SIP-I version defined in SipIEgressISUPVersion property on the outgoing trunk group matches the SIP-I version of the peer devices.
•
Ringback tones are missing.
•
(Finnish SIP-I only) Finnish SIP-I doesn't work.
Action DescriptionStep 1
Check the MPM provisioning on the Cisco PGW 2200 Softswitch
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.

If NOA value is national (significant) number, the format of address signals is NDC2 + SN3 .
•
If NOA value is international number, the format of address signals is CC4 + NDC + SN.
tel URI or SIP URI5
CC + NDC+ SN as an E.164 number in the URI. The number is prefixed with a plus sign.
1 A tel URI or a SIP URI with "user=phone" is used according to operator policy.
2 NDC = national destination code
3 SN = subscriber number
4 CC = country code
5 A tel URI or a SIP URI with "user=phone" is used according to operator policy.
Note
Cisco PGW 2200 Softswitch does not split the address signal into the format, CC + NDC + SN. You can manipulate the address signal (for example, adding CC, or removing CC) by means of dial plan.
