A NP (Numbering Plan) . A numbering plan is a type of numbering scheme with a set of routing rules to allocate telephone numbers to subscribers and to route telephone calls in a telephone network.
A Numbering Plan specifies the format and structure of the numbers used within that plan. It typically consists of decimal digits segmented into groups in order to identify specific elements used for Identification, Routing, and Charging capabilities
Within a business group, there can be multiple numbering plans. At least one Business Group is needed for every dial plan together with one Numbering Plan. In one Business Group, the numbering plan can either be a
When the Numbering Plan is created, a feature profile can be created for all users that are added to this Numbering Plan.
PNP (Private Numbering Plan)
The private numbering plan is a customized plan for business group customers. A business group could be assigned with many numbering plans and all subscribers belonging to that business group could be covered by different Private numbering plan of that business group. A PNP (Private Numbering Plan) is used in a private network by subscribers belonging to either a Tenant, Business, or VPN group. A single Lotus Sametime Unified Telephony supports up to 999 PNPs.
CNP (Common Numbering Plan)
The BG'sCNP (Common Numbering Plan)
is used to set up routing and tranlation rules that are common to one business group (typically when multiple business groups exist). Only one numbering plan per business group can be assigned as a Common numbering plan.The CNP is an optional user-defined PNP which is assigned the type “Common".
GNP (Global/Public/E.164 Numbering Plan)
The GNP (Global Numbering Plan
also known as Public Numbering Plan
or E.164 Numbering Plan
) is used to set up routing rules that are common to all business groups and allow them to communicate with each other. The Global Numbering Plan is often used for interbusiness group call routing. It is separate from Business Groups.
Open and Closed NP (Numbering Plan)
Lotus Sametime Unified Telephony supports closed and open numbering plans as well as implicit and explicit numbering.
Implecit and Explicit Numbering Plans
BG (Business Group)
The Telephony Control Server Assistant Business Groups feature enables you to provision large numbers of related subscribers, such as a business or other organization, at one time. Instead of provisioning individual members of the Business Group (BG), you provision the BG and all members of that BG inherit all of the parameters that you set while provisioning. While you can assign only two services to the BG DN (main number), you can create individual subscribers (BGLs) and provision additional services.
Quick Add BG (Business Group) Feature
The Quick Add Business Group Feature provides a user-friendly and time-saving method of creating a new BG (Business Group) by combining all fields required for creating a BG in one dialog.
Business Group Branch Offices
All subscribers that do NOT belong to a specific Branch Office are considered to belong to the "Main Office" which represents the lack (absence) of a Branch Office. So all subscribers in the Telephony Control Server Assistant are displayed under a specific Branch Office or under a “virtual” Branch Office (Main Office).
A subscriber is a SIP user/a SIP telephone equipped with parameters like telephone number or SIP security settings. Any subscriber belongs to a single business group.
Basic Subscriber Types
Lotus Sametime Unified Telephony subscribers can be categorized into five basic types: Type I, Type II, Type III, Type IV, and Type V.
Defining Subscribers within Lotus Sametime Unified Telephony
This section describes the creation of a basic numbering plan using the Telephony Control Server Assistant tool.
Creating Multiple Subscribers
This feature allows the user to create many subscribers (BGLs) comfortably using an existing subscriber (BGL) as a template.
A unique ID (identification) is assigned to each subscriber. This is typically the public DID number of the subscriber if the subscriber is reachable via DID. However, the subscriber ID need not be a number that is dialable from the PSTN.
Managing BG related Subscribers
Business Groups (BGs) provide a simple method for managing related subscribers. Subscribers (BG members) inherit the features of the Business Group, but the features can be assigned or restricted to individual subscribers.
Quick Add Subscriber
The Quick Add Susbcriber Feature provides a user-friendly and time-saving method of creating a new Subscriber by combining all fields required for creating a Subscriber in one dialog.
Bulk Editing Subscribers
The Bulk Edit
feature allows the user to modify more than one data record of the same entity simultaneously via the GUI.
The Subscriber Templates
dialog is used to list, add, edit and delete a Subscriber Template on behalf of Lotus Sametime Unified Telephony User Management. The subscriber templates are system wide, i.e. not BG related.
BG (Business Group) NP (Numbering Plan) - Normalization
The normalization feature normalizes telephone numbers from local to national format and from national to international format.
BG (Business Group) NP (Numbering Plan) - Types and Codes
The BG (Business Group) NP (Numbering Plans) provide the dialing plans specific to a BG. To reach lines outside of the BG, the caller usually dials an access code.
BG (Business Group) NP (Numbering Plan) - Configuration
In order to permit extension number calling between members of a BG, the BG numbering plan must be configured with the appropriate Prefix access code (New destination code table entries and Extension table entries).
BG NP Configuration - Business Group Extension Number Table
The next step is to add an entry in the BG extensions table. This table has nothing directly to do with defining subscribers. Rather, it is used to define rules that permit Lotus Sametime Unified Telephony to convert between extension numbers and fully qualified subscriber IDs. The extension number may be dialed, but the device, identified by its fully qualified subscriber ID, must be located.
The concept of a Code Index is to provide a 2-step approach to establishing complex translations when multiple routing areas and classes of service are in use. It creates a template for destination code processing, making it easier to administer complex destination code processing scenarios where routing differs on routing areas and classes of service.
Location Codes and Private Numbering Plans
The Location Code defines the segmentation of the dialed numbers. The Location Code is derived from the Prefix Access Code.
PAC (Prefix Access Codes)
The PAC (Prefix Access Code) is the code entered in the numbering plan ( GNP and PNP). A call can only be routed if the dialed digits are matching a PAC.
The Telephony Control Server Assistant provides a generic code processing functionality. The generic code processing is performed after the original called number has been translated in the E.164 code table.
Digit Modification for Digit Outpulsing
The digit modification for digit outpulsing feature provides support for selectively deleting any number of leading digits (up to all digits) from the destination number prefixing new leading digits to the destination number, or both. Digit modification is based on the combination of the Destination Code and the route.
ENUM (Electronic Number Mapping)
ENUM (Electronic Number Mapping) is a DNS-based architecture and protocol for mapping an ITU-T (International Telecommunications Union, Telecommunications Standards Section) recommendation E.164 telephone number into an URI.
Operator ENUM (Electronic Number Mapping) Server
The Operator ENUM Server feature allows up to six ENUM (Electronic Number Mapping) servers to be configured, to list all provisioned ENUM servers, and to create and modify ENUM servers.
ENUM (Electronic Number Mapping) Operator
This feature allows the subscriber to list all provisioned ENUM (Electronic Number Mapping) operators as well as to create and modify ENUM Operators.
Lotus Sametime Unified Telephony, as a VoIP switching system, can be used to create a virtual voice network (a voice VPN) on top of the enterprise's existing data network topology for connecting subscribers within the enterprise, even if these subscribers are in different locations.
Intercepts are sequences of up to three treatments
(for example, tones and/or announcements) Lotus Sametime Unified Telephony and its media servers repeat a specified number of times.
