Restrictions

A control plan may contain as many ENUM NAPTR Response nodes as required.

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.

Configuration screen

Here is an example Configure ENUM NAPTR Response screen.

Configuring the node

Follow these steps to configure the node.

Step	Action
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 overrides 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 listsSelect 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: Select the Extract AUS check box If required, select the Remove + check box to remove the preceding + If required, select the Remove - check box to remove the preceding -
5	In the AUS Save Location section, for AUS format numbers, select the save location from the Profile Location and Profile Field drop down lists.

ENUM Query

Node description

The ENUM Query node is used to query the ENUM database.

Node icon

If the CPE has been configured to use the static panel CPE palette style, the CPE displays the icon shown below to represent the feature node.

Restrictions

A control plan may contain as many ENUM Query nodes as required.

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.

Configuration screen

Here is an example Configure ENUM Query screen.
