This chapter describes features specific to keyset operations. These features provide support for rich collaboration solutions, helping subscribers to better streamline their calling processes
The keyset operations features provide multiple line capability, and other associated functions, for a SIP telephone configured as a keyset. Keysets are sometimes known as multiline telephones.
The keyset line that identifies a keyset telephone. Every keyset phone has a unique primary line.
A line on a keyset that is a shared appearance of a primary line of another keyset, but not of this keyset
The Multiline Appearance (MLA) feature allows for multiple lines (i.e. subscribers) to be assigned to a keyset and for a line to be assigned to multiple keysets. This is particularly useful for executive-assistant arrangements.
The multiline preference feature allows a keyset to automatically select which line it uses when the user originates or answers a call. In addition, it lets a user override the automatic selection of a line and manually select the line to use.
Multiline Origination and Transfer
The multiline origination and transfer feature provides the capability to originate or answer calls at any line appearance at any keyset and to transfer calls via consultation transfer or manual hold.
The delayed ringing feature provides the capability to provision each keyset line key with an option to delay audible ringing when a call is presented to the line. The associated incoming call is not affected.
Audible Ringing on Rollover Lines
The Audible Ringing on Rollover Lines feature permits lines to audibly signal new incoming calls while the subscriber is active on the keyset. This feature is also known as rollover ringing.
Direct Station Selection
The Direct Station Selection (DSS) feature provides a user access to multiple functions for a given internal DN by using a single key (DSS key) with associated status indication. On OpenStage endpoints, DSS keys that can initiate direct calls and have feature override capabilities are known as DSS-direct (DSS-D) keys.
Keyset Operation Modes
The keyset operation modes feature permits an administrator to specify whether a keyset telephone uses the data of the primary line or the data of the line in use for call origination and features.
The line focus feature ensures that the OpenStage or optiPoint display contains the appropriate information, depending on the keyset line currently in use.
Line Key Operation Modes
The Line Key Operation Modes feature provides the capability to automatically place an active line on manual hold.
The Line Reservation feature is available for OpenStage and optiPoint keyset telephones. It permits a keyset user to reserve a line when dialing a destination or selecting a line.
The Manual Hold Feature allows a keyset user to place the call on the active line in a waiting position. The keyset user can then go onhook without losing the call and can place or answer another call on a different line key.
A Phantom Line is identical to a normal line in all respects, except that a Phantom Line is not assigned to any device as a primary line. This line type can appear as a private line on one keyset or as a shared secondary line on two or more keysets.
Visual Indicators for Line and Feature Key Status
The Visual Indicator features allow the keyset user to view the various states (for example, ringing, hold, consult) of a line via its associated LED and to view the various states of a feature key (for example, call pickup group) via its associated LED.
Bridged Calls and Privacy
The Bridged Call feature permits keyset users with a shared multi-line appearance to establish or join a station-controlled large conference by pressing the line key of the line they wish to bridge onto. Lines can be protected against bridging by setting the privacy flag (default).
3rd Call Leg
The 3rd Call Leg Feature allows to handle three simultaneous calls at a keyset telephone.
Multiple Prime Line Registrations
Since 184.108.40.206 of Lotus Sametime Unified Telephony a subscriber can register as the primary line from more than one keyset device at the same time - without requiring additional dynamic licenses.
