INFO: Use the following command syntax to enable EDNS support (refer to DNS Group - CLI for command details):

% set addressContext <addressContext Name> dnsGroup <dnsGroup Name> ednsSupport enabled

e911

N/A

Use this parameter to configure enhanced 911 service.

• criteria triggerCriteria <criteria>
• defaultTreatment– Default treatment to apply for requests that time out.
  • applyFinalTreatment
  • routeAsDialed (default)
• flags active
  • disable (default)
  • enable
• requestTimeOut – (range: 0-2147483647 / default = 4000)

  • local
  • lro (default)

e911VpcDevice

N/A

Use this object to configure the IP address and port number of the E911 VoIP Positioning Center (VPC) device. This parameter is used  for queries to one or more E911 VPCs for the Emergency Services Routing Number of the Public Services Answering Point nearest the current location of the caller.

• deviceData <call priority: 0-32767>
  • ipAddress <IPv4 or IPv6 address>
  • portNumber <0-65535>

<domain_name> – Name of the ENUM domain containing forwarderIP entries for load balancing.

• forwardersData <priority #> – Priority or sequence number of each forwarderIP defined below. A lower value represents a higher priority. This value is unique for each forwarderIP. (range: 0-99999).
  
  • forwarderDescription <description> – Textual description of each fowarderIP entry.
  • forwarderIP <IPv4 or IPv6 address> – ENUM server IPv4 or IPv6 address of this forwarderIP entry.
• loadDistribution  – Load distribution strategy. Refer to ENUM Support for details.
  
  • proportion
    • percentageDistribution – The percentage of load distribution to calculate for each IP in enumDomainName (range: 0-99999).
  • roundRobin
  • sequence (default)

• queryRetryTimer – The time, in milliseconds, that SLWRESD process waits before trying the next IP in the forwardersData list (range: 0-10000 | default = 4000).
• zoneType individual – The zone type for this ENUM domain (At present, "individual" is the only zone type available, and it indicates SBC supports load balancing across individual zones).

NOTE: All forwarderIP entries for this enumDomainName must be configured with the same loadDistribution type and queryRetryTimer value because attributes apply to ENUM domain, not individual forwarderIP entries.

INFO: Refer to ENUM Support for additional feature details and descriptions.

<ENUM domain name label> – A collection of ENUM domains used by SLWRESD process for performing ENUM queries. The default enumDomainNameLabel value is "DEFAULT_ZONE_LABEL".

• enumDomainNameId <enumDomainName's name> – The enumDomainName of each ENUM domain to attach to this enumDomainNameLabel.

<profile name> – Profile name used by the SLWRESD process. The SLWRESD process uses ENUM zones configured for sending ENUM queries against an enumDomainLabel (and receiving responses) using either the management or signaling interfaces, depending upon the lwresdProfile type setting (see the table below). The default profile name is "DEFAULT".

See LWRESD Profile Parameters table below for parameter details.

<profile name> – Profile name used by the SLWRESD process. The default profile name is "DEFAULT". The SLWRESD process uses the ENUM zones configured for performing an ENUM query against enumDomainLabel.

NOTE: Only one lwresdProfile is allowed.

<address context name> – The name of the Address Context containing the IP Interface Group to use for communicating with the external DNS server.

NOTE: This parameter is available when type = ip.

<description> – Enter a textual description (within quotation marks) of the LWRESD Profile.

Use this flag to enable/disable LWRESD logging.

• disable (default)
• enable

Use this parameter to specify the interface type supported by the Policy Server (external PSX).

• ip – Uses port 988.
• mgmt (default) – Uses ports 49152 to 65535.

The name of the Address Context containing <IPIG name> – The name of the IP Interface Group to use for communicating with the external PSXDNS server.

NOTE: This parameter is available when type = i ip.

Use this parameter to specify the interface type supported by the external DNS server.

• ip – The PSX uses port 988.
• mgmt (default) – The PSX uses ports 49152 to 65535

The name of the IP Interface Group to use for communicating with the external PSX.

• .

Default treatment to apply to this ENUM Service.

• applyFinalTreatment
• routeAsDialed (default)

Use this parameter to specify how to treat ENUM definitions.

• privateDomainNameForEnumLookups <private_domain_name> – Specify the private domain name to use for ENUM look-ups.

• active
  • disable (default)
  • enable
• processCallingNumber –Enable this flag to analyze the calling number using prefix profile. When this flag is disabled, the calling number is not analyzed and hence if it has +CC, the same is sent as-is to SBC in the calling number field in policy response.
  • disable (default)
  • enable
• processNewANI – When this flag is enabled for ENUM AoR service, and ENUM AoR response contains "newani=<some_number>" parameter in NAPTR record, the ERE overwrites the existing calling number of the call with the newANI number. When this flag is disabled, any newANIparameters received in NAPTR response are ignored in PES.
  • disable (default)
  • enable

Specifies the priority (order) of ENUM service execution. If this parameter is not set or set to the default of '129', default priorities are assigned for LNP (130), CNAM (131) and SIP AoR (132). If a different order of service execution is desired, set the priorities accordingly.

For example, setting CNAM priority to 133 executes SIP AoR before CNAM.

Use this parameter to specify the ENUM service type. Options are:

• cnam

• lnp
• sipAor
