The Lookup Number Block object is a child of the On-Switch and LNP Lookups object.
Each Lookup Number Block object contains information about the telephone numbers expected to be present in a local area managed by the MetaSwitch NE. These include numbers that may be ported to or from the switch if Local Number Portability is allowed, and ranges of non-geographic numbers where some but not all numbers in the range are owned by the switch.

Description
|
Number block prefix
|
Change
|
E164 address, including the NPA, which defines a block of telephone numbers.
|
Number block name
|
Change
|
A text string used in the EMS System Explorer to identify this Lookup Number Block object. Specify a string of up to 64 characters.
|
Number block type

Change
|
Specifies whether the block of telephone numbers is owned exclusively by this switch, or includes ported or non-geographic numbers. The values relating to ported numbers are valid only if the Config Set type of the parent Config Set is set to No LNP lookup or LNP lookup. Note that if a subscriber has Force LNP lookup set to True, this overrides the behavior described below, forcing a lookup even if the target number is found on this switch. Values:
- Owned (default)
The specified number block is owned exclusively by the switch for routing purposes. These numbers cannot be ported, and the NE will not do any LNP lookups for numbers in this block. Call routing attempts to numbers in this block will fail if the target number is not found on the switch.
- Owned but may be ported away
The specified number block is owned by the switch, but numbers within the block may have been ported away. The NE will first look for the number on the switch, but will do an LNP lookup if one has not already been done and the on-switch check fails. Call routing attempts to numbers in this block will fail if the LNP lookup returns the original number or this switch's LRN; otherwise the number returned by the LNP lookup is used for Trunk Routing.
- Not owned but may be ported to
The specified number block is not owned by this switch but numbers within it may be ported to this switch. The NE will first look for the number on this switch, but will do an LNP lookup if one has not already been done and the on-switch check fails. Call routing attempts to numbers in this block will fail if the LNP lookup returns this switch's LRN; otherwise the number returned by the LNP lookup is used for Trunk Routing.
- Not owned but may be ported to served exchange
The specified number block is not owned by this switch, but numbers within it may be ported to another exchange in the local area for which this switch provides LNP lookups. The NE will do an LNP lookup but will not look for the target number on this switch. Call routing attempts to numbers in this block will fail if the LNP lookup returns this switch's LRN; otherwise the number returned by the LNP lookup is used for Trunk Routing.
- Sparsely owned
The specified number block is a number range in which one or more numbers are owned by this switch but others may be owned by remote exchanges. This is used when non-geographic numbers are owned by this switch, or when one or more numbers in the range are owned by this switch but others are owned by a legacy Class 5 switch for which this switch may be providing Point Code Proxy functions. The NE will first look for the number on this switch, but will perform Trunk Routing if the target number is not found on the switch.
- Sparsely owned and maybe ported away
The specified number block is a number range in which one or more numbers are owned by this switch, one or more numbers are owned by a legacy Class 5 switch for which this switch provides Point Code Proxy functions, and others may be ported away from these switches. The NE will first look for the number on this switch, but will perform an LNP lookup followed by Trunk Routing if the target number is not found on the switch.

Associated Signaling Gateway
|
Change
|
The Signaling Gateway associated with the local area. If Number Validation determines that an LNP request is required because the number belongs to this Lookup Number Block, the request will be sent from this Signaling Gateway (unless a different gateway is specified as part of the routing attributes).
Select from the displayed list of Signaling Gateways, or select None if you do not want to specify one.
If no gateway is specified here or in routing, or if the gateway specified here has been deleted, the query is sent from the originating Signaling Gateway associated with the call (if any), or from any Signaling Gateway that has a suitable Local Service Access Point configured.
