SIP Profiles

A profile allows you to create a specific set of characteristics different from the standard

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
• recoveryAlgTimerDuration: 1 second
• recoveryAlgorithm: probe

SIP/CPC Cause Code Mapping Profiles

The Cause Map Profile, SIP-to-CPC and CPC-to-SIP mappings provide customized tables on the

The following IPSP configurations are added to PSX under SIP Cause Mapping section to specify the Cause Code Mapping profile name.

• Internal to SIP Cause Mapping Profile Name
• SIP to Internal Cause Mapping Profile Name

PSX returns the Cause Code profile name in the POL responses.

1. If a policy response contains a profile name and a locally configured profile uses the same name,

   Unable to show "metadata-from": No such page "_space_variables"
   applies the same name.

2. If a policy response does not contain a profile name or if the profile name does not match with any local profile,

   Unable to show "metadata-from": No such page "_space_variables"
   applies the SIP Trunk Group created local profile name (if created).

3. Unable to show "metadata-from": No such page "_space_variables"
   applies a default profile name if none of the above two cases match.

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 see Call Admission Controls topic.
• 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.

See the following pages for configuration details:

• EMA: Service Profiles - Emergency Call Profile
• CLI: Emergency Call Profile - CLI

SIP JIP Profile

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

The inclusion of the JIP parameter in SIP INVITE message allows the 

JIP information can be carried in the P-Asserted-ID/FROM and P-DCS-Billing-Info headers of SIP INVITE message and in the PDCS header in a 3xx response. The

Multiple controls can be enabled at a time to select the header or parameter from which JIP value will be extracted. When multiple controls are configured, JIP information is extracted in the following order:

• RN PARAMETER IN PAI
• JIP PARAMETER IN PAI
• RN PARAMETER IN FROM
• JIP PARAMETER IN PDCS

See the following pages for configuration details:

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.

The

  Unable to show "metadata-from": No such page "_space_variables"
  then performs OCSP status checking for each certificate in the chain.

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.

• OCSP capability
  • enabled
  • disabled (default)
• Default responder URI (default: blank):
  
  • IPv4 address and port number, or
  • 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 response waiting time - If the corresponding OCSP response does not return before the time expires after sending an OCSP request, the response is considered unavailable.
  
  • Range: 1-16 seconds, default = 2.

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.

Linux DNS Client Support

Linux DNS client functionality is required for OpenSSL OCSP API to translate a FQDN to an IPv4 address. To populate the file with DNS server addresses, use following CLI commands.

% set addressContext default dnsGroup d1 type mgmt server dns1 ipAddress 10.11.12.13 state enabled
% set addressContext default dnsGroup d1 type mgmt server dns2 ipAddress 10.11.12.15 state enabled

Transparency Profile

The  supports flexible header transparency feature which allows a user to define a set of SIP header names using a configuration interface to the Transparency Profile (TP), and then assign that profile to a Trunk Group (TG). For example, if a header name is in the TP corresponding to the egress leg (respective to the message), it is passed through unmodified with its full content, including all parameters. This applies to all initial INVITE, REGISTER and mid-INVITE initiated dialog requests and responses (excluding mid-dialog SUBSCRIBE requests and responses sent in the context of an existing dialog). Corresponding relay flags for other mid-dialog requests (e.g. INFO, MESSAGE, NOTIFY) must be enabled for this functionality to work.

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
• Content-Disposition
