Feature Overview
The introduction of the Support for SIP-T and SIP-GTD feature allows the Cisco MGC to send ISDN User Part (ISUP) parameters through SIP networks. This feature also enables the Cisco MGC to support end-to-end ISUP transparency.
This feature supports the encapsulation of MIME-encoded binary ISUP within SIP messages using SIP-T, and MIME-encoded GTD within SIP messages. SIP-T is used where use of open protocols is most important. SIP-T enables end-to-end ISUP transparency between networks using German ISUP.
SIP-GTD is used to enable connection between networks using different ISUP types, provide the ability to transfer a subset of parameters to reduce overhead as compared to SIP-T (with Native ISUP). SIP-GTD can be provisioned on outgoing SIP trunk groups.
Benefits
This feature has the following benefits:
Enables end-to-end ISUP transparency through SIP networks
In a plain SIP network, some ISUP parameters are interworked with SIP information in the messages. There is no one-to-one mapping for the ISUP parameters. By using SIP-T or SIP-GTD, the ISUP parameters can be transported from ingress to egress.
Use of ISUP parameters in SIP networks
Not all ISUP parameters are interworked with SIP. Using SIP-GTD, a subset or all of the ISUP parameters can be exposed in SIP networks.
Restrictions
This feature has the following restrictions:
•It can only be used with connections to media gateways or softswitches that support SIP-T and/or SIP-GTD.
•SIP-T is only supported for German ISUP.
•SIP-T works only when both Cisco MGCs are configured for German ISUP.
Related Features and Technologies
This feature is related to the feature that adds support of GTD to SIP media gateways.

Provisioning Procedures
The provisioning procedures for this feature can be found in the following sections:
• Adding Support of SIP-T and SIP-GTD
• Modifying SIP-T and SIP-GTD values
• Disabling Support of SIP-T and SIP-GTD
Provisioning Basics
The procedures in this section describe how to start a provisioning session and how to save and activate the changes you have made.
• Starting a Provisioning Session
• Saving and Activating your Provisioning Changes
• Ending a Provisioning Session Without Activating your Changes
• Retrieving Provisioning Data
For more detailed information about provisioning your Cisco PGW 2200, refer to the Cisco Media Gateway Controller Software Release 9 Provisioning Guide.
Starting a Provisioning Session
You may need to start a provisioning session as part of your system operations. To do this, log into the active Cisco MGC, start an MML session, and enter the following command:
mml>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:
Note If you do not know the name of your current configuration session, you can use the procedure in the "Retrieving Data on the Current Provisioning Session" section.
–new—A new default session configuration; no existing source configuration is available.
–active—Selects the active configuration as the source for configuration changes.
Note You can use new as the source configuration only when there is no existing, active set of provisioning data in the configuration library. Therefore, new cannot be used as the source configuration once a provisioning session has been saved and activated by using prov-cpy or prov-dply. Once you have saved and activated a set of data, you must use either active or the name of the set of provisioning data as the source configuration.
•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:
mml>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. For more information on provisioning other functions on your Cisco MGC software, 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 or ending your provisioning session without saving and activating your changes, as described in the "Ending a Provisioning Session Without Activating your Changes" section.
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.
Caution Using the prov-cpy and prov-dply MML commands 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.
The prov-cpy MML command is used to save and activate your changes on the active Cisco MGC. This command is typically used to save and activate changes on a Cisco MGC in a simplex configuration. However, you can use the prov-cpy MML command on Cisco MGCs in high-availability or continuous-service configurations, to save and activate your changes on the active Cisco MGC. If you choose to do this, you should enter the prov-sync MML command immediately afterwards, to have your changes saved and activated on the standby Cisco MGC.
Note When you enter the prov-cpy command, your provisioning session is also 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.
Caution Using the prov-sync MML command can severely impact your system's call processing performance. We recommend that this command be issued during a maintenance window when traffic is minimal.
Note When the prov-sync MML command is used to synchronize the provisioning settings on the standby MGC host with current settings on the active MGC host, the system does not indicate when the synchronization process has failed.
The prov-dply MML command is used to save and activate your changes on the active and standby
Cisco MGCs. This command is typically used to save and activate changes on Cisco MGCs in high-availability or continuous-service configurations. This command should not be used on a Cisco MGC in a simplex configuration.
Note When you enter the prov-dply command, your provisioning session is also 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.
Ending a Provisioning Session Without Activating your Changes
You may find that you want to end a provisioning session without saving and activating the changes you have entered during your session. If this is the case, you can 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 in which you can use this command to retrieve provisioning data are described in the following sections:
• Retrieving Data for an Individual Component
• Retrieving Data for All Components
• Retrieving Data for All Components of a Particular Type
• Retrieving Data on the Current Provisioning Session
• Retrieving Data on Supported Signaling Protocols
Retrieving Data for an Individual Component
You can retrieve provisioning data on any individual component on your system. To do this, log in to the active Cisco MGC, start an MML session, and enter the following command:
mml>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 value of GTD properties for a GTD parameter set called t3, you would enter the following command:
mml>prov-rtrv:gtdparam:name="t3"
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:
mml>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:
mml>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.
For example, to view the provisioning data for all SS7 signaling services, you would enter the following command:
mml>prov-rtrv:ss7path:"all"
Retrieving Data on the Current Provisioning Session
You can retrieve provisioning data on the current provisioning session. To do this, log in to the active Cisco MGC, start an MML session, and enter the following command:
mml>prov-rtrv:session
The system returns a response similar to the following:
MGC-02 - Media Gateway Controller 2003-01-13 13:39:19
M RTRV
"session=jtest:session"
/*
Session ID = mml1
SRCVER = active
DSTVER = jtest
*/
Retrieving Data on Supported Signaling Protocols
You can retrieve protocol data for the current provisioning session. To do this, log in to the active Cisco MGC, start an MML session, and enter the following command:
mml>prov-rtrv:variants

To enable the early backward ISUP message on GTD-enabled SIP trunk groups, perform the following steps:
Step 1 Enter the following command to enable the early backward ISUP message on a SIP trunk group:
mml>prov-ed:trnkgrpprop:name="num", IsupTransEarlyBackwardDisabled="0"
Where num is the number of a previously provisioned trunk group.
Note The default value for this property is 1 (Disabled).
For example, to enable the early backward ISUP message on trunk group 1000, you would enter the following command:
mml>prov-ed:trnkgrpprop:name="1000", IsupTransEarlyBackwardDisabled="0"
Step 2 Repeat Step 2 for each SIP trunk group on which you want to enable the early backward ISUP message.

Step 1 Enter the following command to enable a GTD parameter on a trunk group:
mml>prov-ed:trnkgrpprop:name="num", gtdcaptypeprop="paramstring"
Where:
•num—Number of a previously provisioned trunk group.
•paramstring—String identifying which set of GTD parameters are applied to this trunk group. Valid value are:
–MML name of a previously provisioned GTD parameter set.
–t0—No GTD parameter set (default)
For example, to enable a GTD parameters set on trunk group 1000, you would enter the following command:
mml>prov-ed:trnkgrpprop:name="1000", gtdcaptypeprop="t2"
Step 2 Repeat Step 2 for each trunk group on which you want to enable a GTD parameter set.
Adding DNS Parameters
To provision DNS parameters, enter the following command:
mml>prov-add:dnsparam:dnsserver1="serv1", dnsserver2="serv2", cachesize="cache", ttl="timlive", policy="pol_type", querytimeout="qtimout", keepalive="kptime"
Where:
•serv1—IP address of primary DNS server.
•serv2—IP address of secondary DNS server. This is an optional parameter.
•cache—Maximum number of cache entries used to hold DNS entries. Valid value is any integer greater than 0. The default value is 500.
•timlive—Time-to-live interval for DNS entries, expressed in seconds. Valid value is any integer greater than 0. The default value is 3600.
•pol_type—Policy type used for selecting DNS entries. Valid values are hierarchy and round-robin. The default value is hierarchy.
•qtimout—Timeout interval for DNS queries, expressed in milliseconds. Valid value is any integer greater than 0. The default value is 1000.
•kptime—Time interval to determine whether DNS server is responding, expressed in seconds. Valid value is any integer greater than 0. The default value is 30.
For example, to provision DNS parameters, you would enter the following command:
mml>prov-add:dnsparam:dnsserver1="172.22.121.42", dnsserver2="171.69.2.133", cachesize="500", ttl="3600", policy="hierarchy", querytimeout="1000", keepalive="30"

mml>prov-ed:gtdparam:name="name", desc="description", gtdparamstring="gtdparams"
Note The overridestring GTD subcommand is not valid for use with SIP.
Where:
•name—The name you want to give to the component. The name can be as many as 20 characters long and can contain numbers, letters, and the dash (-) symbol. The name should begin with a letter.
•description—The long name assigned that can be as many as 128 alphanumeric characters in length.
•gtdparams—A string of parameters that defines the ISUP messages and parameters that are transparently transported by the Cisco MGC. The maximum length of the string is 460 characters. The valid values are as follows:
–ALL
–Individual ISUP parameter codes (a complete list of valid ISUP parameter codes can be found in Table 12 and Table 13.)
Note If you enable GTD on your system, the following ISUP parameter codes are always allowed, regardless of your individual selections: EVI, GCI, PCI, PRN, MCI and FDC.
For example, to modify a GTD parameter set to support all of the GTD parameters, you would enter the following command:
mml>prov-ed:gtdparam:name="t1", gtdparamstring="ALL"
In another example, you can modify a GTD parameter set to supports select GTD parameters by entering the following command:
mml>prov-ed:gtdparam:name="t2", gtdparamstring="BCI, CPC, CGN, CIC, CPN, MCR"
Step 3 Repeat Step 1 for each set of GTD parameters you want to modify.
Step 4 If there are no other components that you need to provision, end your provisioning session as described in the "Saving and Activating your Provisioning Changes" section.
Disabling the Early Backward ISUP Message
To disable the early backward ISUP message on GTD-enabled SIP trunk groups, perform the following steps:
Step 1 Start a provisioning session as described in the "Starting a Provisioning Session" section.
Step 2 Enter the following command to disable the early backward ISUP message on a SIP trunk group:
mml>prov-ed:trnkgrpprop:name="num", IsupTransEarlyBackwardDisabled="1"
Where num is the number of a previously provisioned trunk group.
For example, to disable the early backward ISUP message on trunk group 1000, you would enter the following command:
mml>prov-ed:trnkgrpprop:name="1000", IsupTransEarlyBackwardDisabled="1"
Step 3 Repeat Step 2 for each SIP trunk group on which you want to disable the early backward ISUP message.
Step 4 If there are no other components that you need to provision, end your provisioning session as described in the "Saving and Activating your Provisioning Changes" section.
Changing GTD Parameter Sets
To change GTD parameter sets on GTD-enabled trunk groups, perform the following steps:
Step 1 Start a provisioning session as described in the "Starting a Provisioning Session" section.
Step 2 Enter the following command to enable a GTD parameter on a trunk group:
mml>prov-ed:trnkgrpprop:name="num", gtdcaptypeprop="paramstring"
Where:
•num—Number of a previously provisioned trunk group.
•paramstring—String identifying which set of GTD parameters are applied to this trunk group. Valid value are:
–MML name of a previously provisioned GTD parameter set.
–t0—No GTD parameter set (default)
For example, to enable a different GTD parameters set on trunk group 1000, you would enter the following command:
mml>prov-ed:trnkgrpprop:name="1000", gtdcaptypeprop="t3"
Step 3 Repeat Step 2 for each trunk group on which you want to enable a GTD parameter set.
Step 4 If there are no other components that you need to provision, end your provisioning session as described in the "Saving and Activating your Provisioning Changes" section.
Disabling Support of SIP-T and SIP-GTD
To disable support of SIP-T and SIP-GTD, you must modify the value of a property for the ingress SS7 and SIP trunk groups. To do this, perform the following steps:
Step 1 Start a provisioning session as described in the "Starting a Provisioning Session" section.
Step 2 Enter the following command to disable support of SIP-T and SIP-GTD on the ingress SS7 trunk group:
mml>prov-ed:trnkgrpprop:name="name", sipMimeBodySupport="0"
Where: name is the MML name of the previously configured ingress SS7 trunk group.
For example, to disable support of SIP-T on trunk group 1000, you would enter the following command:
mml>prov-ed:trnkgrpprop:name="1000", sipMimeBodySupport="0"
Step 3 Repeat Step 2 for the SIP trunk group.
Step 4 If there are no other components that you need to provision, end your provisioning session as described in the "Saving and Activating your Provisioning Changes" section.
Troubleshooting Tips
There are no alarms specific to this feature. If you find that you are having trouble with your system and you suspect a SIP-T or SIP-GTD error, verify the provisioning data for the system. If your system is incorrectly configured, fix the faulty data. If that does not resolve the problem, or if your system is correctly configured, contact the Cisco TAC for assistance. Refer to "Obtaining Documentation" section on page 36 for more information about contacting the Cisco TAC.

Cisco Product Security Overview
Cisco provides a free online Security Vulnerability Policy portal at this URL:
http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html
From this site, you can perform these tasks:
•Report security vulnerabilities in Cisco products.
•Obtain assistance with security incidents that involve Cisco products.
•Register to receive security information from Cisco.
A current list of security advisories and notices for Cisco products is available at this URL:
If you prefer to see advisories and notices as they are updated in real time, you can access a Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed from this URL:
http://www.cisco.com/en/US/products/products_psirt_rss_feed.html
Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:
•Emergencies — security-alert@cisco.com
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•Nonemergencies — psirt@cisco.com
In an emergency, you can also reach PSIRT by telephone:
•1 877 228-7302
•1 408 525-6532
Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive information that you send to Cisco. PSIRT can work from encrypted information that is compatible with PGP versions 2.x through 8.x.
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
