ENUM Naptr Response

The ENUM NAPTR Response node processes a previously retrieved NAPTR response to extract specific records.

When extracting AUS (Application Unique String) type, the presence of the AUS is detected by a ‘+’ character found, followed by one or more numerical characters terminated with ‘@’ (for example "!^.*$!+441473289900@oracle.com!")

Node exits

This node has one entry and four exits. The number of exits cannot be changed.

Exit Cause Description
1 Success The record was extracted and saved.
2 No Match NAPTR The required record could not be found.
3 No Match AUS An AUS format number could not be found.
4 Error Any other error situation.

Configuring the node

Follow these steps to configure the node.

  1. In the Search String section, set the search criteria to match records against.

    • Enter the record type to extract in the Search String field

    • Enter the record number to extract in the Index field

  2. In the Active Record Save Location, identify where the found record is to be saved, one of:

    • A new location, select from the Profile Location and Profile Field drop down lists

    • Same location, select the Overwrite NAPTR check box

    Note: selecting this check box over-rides any profile selection.

  3. In the Regular Expression Substitution section, to invoke the regular expression substitution, check the Perform Substitution check box, then:

    • Identify incoming profile location, one of:

      • Select an incoming AUS value from the Incoming Profile Location and Incoming Profile Field drop down lists

      • Select the Use Default Profile check box

    • Select a save location from the Outgoing Profile Location and Outgoing Profile Field drop down lists

  4. In the AUS Processing section, for AUS format numbers extracted:

Node exits

This node has one entry and five exits. The number of exits cannot be changed.

Exit Cause Description
1 Subscriber records

Search key found subscriber records that matched the search key (dialed number within a record number range) and may have matched the optional Service criteria.

Note: The search key is used to find subscribers/operators. This is a dialed number (for example, 1234567) that is searched for between a range of numbers.

2 Operator records Search key did not find any subscriber records, but did find operator records that matched the search key (dialed number within a record number range) and may have matched the optional Service criteria.
3 No NAPTR Records Search key did find subscriber or operator records that matched the search key but did not find any NAPTR records.
4 No SUB/OP info Search key did not find any subscriber or operator records that matched the search key.
5 Error Database or I/O error.

Note: The Service criteria is an optional delimiter for the NAPTR record returned. By specifying the service you can delimit on the service of a NATPR records (that is, only return records of E2U+sip type). The search key is still the primary search criteria.

Follow these steps to configure the node.

  1. Select the Search Key Location, one of:

    • Select from the drop down lists

    • Select the Use Default Profile check box

  2. To optionally specify a Service Type:
