SIP ARS Profile

To achieve efficient device failover to the backup/secondary Application Server, the

These ARS profiles can be assigned to the services section of a SIP trunk group to enforce the blacklisting and recovery of any SIP peer(s) associated with the trunk group. If no recovery algorithm is specified when configuring a SIP ARS profile, the recovery algorithm default values are used as indicated below:

• recoveryAlgProbeDuration: 1 second
• recoveryAlgProbeInterval: 1 second
• recoveryAlgProbeMethod: sip-options
• recoveryAlgProbeNumResponses: 1

SIP Emergency Call Profile

This object creates and configures an Emergency Call Profile for SIP calls used to host emergency call criteria. The emergency call classification methods are:

• Emergency Call Marking: The cpc-priority in P-Asserted Identities is present in the INVITE message, and the CPC parameter of the SIP EMERGENCY PROFILE is set to “priority”.
• Prefix Matching (up to three prefixes): At least one of the three emergency prefixes is configured in SIP EMERGENCY PROFILE and the R-URI header in the INVITE message matches one of the three emergency prefixes. The emergency prefix is an alphanumeric string that consists of numeric digits (phone number). For more information refer to Call Admission Controls.
• URN Prefix: Emergency prefix URN, for example “services:sos”.
• X-EMG Header: Use this flag to determine whether SIP X-EMG header should be accepted as an emergency call indicator.

• EMA: Service Profiles - Emergency Call Profile

SIP JIP Profile

The Jurisdiction Information Parameter (JIP) is a 6-digit field (NPA-NXX format) in an ISUP IAM message used to indicate the geographic location of the originating caller or switch. This information may be used in billing. 

The SBC supports sending JIP information in SIP-SIP, SIP-SIP-I and SIP-I to SIP scenarios. This capability is enabled/disabled through the SIP Jurisdiction Support option (sipJurisdictionSupport flag) set in the SIP trunk group, and specific processing details are controlled through the SIP JIP profile assigned to the trunk group.

When SIP Jurisdiction support is enabled, options in the SIP JIP profile assigned to the ingress SIP trunk group specify where to extract the SIP JIP value from in an incoming SIP INVITE message. The SBC can take the JIP value from the following parameters:

• rn parameter in the PAI header
• jip parameter in the PAI header
• rn parameter in the From header
• jip parameter in the P-DCS-Billing-Info header

Note that if a SIP JIP profile enables more than one possible source parameter, the SBC prioritizes them in the order shown above.

The SBC sends the JIP value it extracts to the external PSX. Based on its configuration, the PSX determines what JIP value should be sent out and returns this value to the SBC.

In the outgoing message, the SBC sends the JIP it received from the PSX in the parameter specified in the SIP JIP profile assigned to the egress SIP trunk group. The parameter options are the same as the source choices:

• rn parameter in the PAI header
• jip parameter in the PAI header
• rn parameter in the From header
• jip parameter in the P-DCS-Billing-Info header

For cases when the JIP value is sent in a P-DCS-Billing-Info header, the SIP trunk group also includes a parameter (feidForPDCS) in which you can specify a Financial-Entity-ID (FEID) to be sent out in the egress PDCS-Billing-Info header. An FEID consists of hexadecimal string of up to 16 characters followed by a domain name. 

The SBC records JIP-related details in the Call Detail Record.

SIP OCSP Profile

The Online Certificate Status Protocol (OCSP) enables

When a peer sends certificates, an OCSP client (e.g. SIPFE) issues a status request to an OCSP responder and suspends acceptance of the certificates in question until the responder provides a response. The OCSP client needs the address/URL of the OCSP responder, the certificate to be checked, and the certificate issuer’s certificate. The OCSP URL can be FQDN or IPv4 address plus port number.

Key Concepts

The user may create up to four OCSP profiles per system, each specifying the OCSP capabilities and protocol parameters applying to one or more TLS connections that use the profile (a SIP/TLS connection may reference an OCSP profile in its assigned TLS profile). The OCSP profile is referenced by the existing TLS profile.

  • FQDN
• AIA override:
  • enabled - Forces the use of configured Default responder for OCSP validation regardless of whether or not the certificate being validated references a responder by AIA.
  • disabled (default) - The responder referenced via AIA by the certificate being validated is used, or the Default responder as configured is used only if the AIA is not available.
• OCSP Stapling
  
  • disabled (default)

  • Range: 1-16 seconds. Default: 2.
• OCSP Response Caching Timer
  • Range: 1-30 days. Default: 1.

When configuring an OCSP profile, be aware that you may delete a given OCSP profile when it is not referenced by any TLS connections.

When OCSP is enabled for a TLS connection, every individual certificate in the chain presented by the peer device during the establishment of the connection is validated against an OCSP responder for its revocation status.

Transparency Profile

If a header is not in the transparency configurable, existing “Unknown Header Transparency” and explicit header transparency flag semantics shall apply.

This feature allows you to add previously “unknown” headers to the TP making them “semi-known” to the system, as well as add “known” headers thus eliminating the need for IP Signaling Profile (IPSP) transparency control flags for those headers. An "unknown" header is defined as a header that, if present in an incoming SIP message, is parsed as a generic “unknown” header, but is treated as a “known” header with respect to transparency by allowing individual transparency control towards it.

If you configure a Contact header in the Transparency Profile, it is treated as full contact header transparency.

Support for known headers (with or without IPSP transparency flags) is available for INVITE, REGISTER and OOD messages. Support for selective unknown header transparency is available for INVITE, REGISTER messages.

The following message body headers cannot be used when configuring a Transparency Profile:

• Content-Encoding
• Mime-Version
