This package of features is a collection of functions usable for subscribers.
Business Group Features
The BG (Business Group) concept provides the basic capabilities for handling a group of subscribers associated with a single enterprise simplify such tasks. Subscriber and EP (Endpoint) features allow further different usage and configuration. It also permits Lotus Sametime Unified Telephony to recognize the associations of the subscribers.
Subscriber Features (a.k.a. services) in Lotus Sametime Unified Telephony represent end user telephony functionality - most of them related with call processing. Features can be implicitly (via an associated Feature Profile) or/and explicitly assigned to subscribers.
Station Restriction Features
Station Restriction Features provide static
limitations on calls originated or terminated at a Business Group’s subscribers and endpoints based on a generic or administrator-defined traffic classification.
Calling Services features are available for the Lotus Sametime Unified Telephony supported SIP endpoints, including Lotus Sametime Unified Telephony SIP telephones, the softclient, the Telephony Application Server Personal Edition, and third-party SIP endpoints. For the applicable services detailed information is given about local and Lotus Sametime Unified Telephony-based features available to the end user.
Calling Identity Services
The CIS (Calling Identity Services) are a collection of features related to call related Identity Management. The delivered Number and Name form a user's identity and can be presented to the called or calling party. The information may be updated as the call progresses.
Attendants features are supported by Lotus Sametime Unified Telephony. It uses an attendant console desktop that includes the productivity features of the agent desktop and several attendant-specific features. Attendants can be located anywhere the IP network extends because the desktop integrates on top of the attendant's SIP EP (Endpoint).
Subscriber Location Identification
A characteristic of IP communication environments is the ability to move phones and other clients within the corporate network. For certain call processing features such as E911 (Enhanced 911) or CAC (Call Admission Control), subscriber mobility is a challenge, because the adequate call handling depends on the current geographical location of the calling and/or called party. Lotus Sametime Unified Telephony supports several location identification concepts.
CAC (Call Admission Control)
Lotus Sametime Unified Telephonys's CAC (Call Admission Control), also known as IRM (Internal Resource Management) is the mechanism by which new calls may be refused by Lotus Sametime Unified Telephony, if the IP network does not have the capacity (bandwidth) to handle the call with a acceptable quality of service.
When an emergency call is made from within the internal corporate network, Lotus Sametime Unified Telephony's built-in E911 (Enhanced 911) support provides the capability to forward the call to the gateway served by the appropriate PSAP (Public Safety Answering Point) jurisdiction. By conveying location identifiers registered in the PSAP's ALI (Automatic Location Identification) database, it enables the PSAP operator to retrieve information about the caller's geographical location and place a response call to either the originator of the emergency call or a designated on-site destination.
How to Create a Feature Access Code
A Feature Access Code is a special instance of a PAC (Prefix Access Code), defining a sequence of keys (0 - 9, #, *) that enables callers to invoke a specific server-side feature. A Feature Access Code can either be assigned globally (i.e. in the Global Numbering Plan) or locally (i.e. in a Private Numbering Plan).
