Chapter 1 Solution Overview
Solution Features
Call Transfer (CT)
CT allows a user to add a third party or second call to an existing two-party call. CT also allows the user
to hang up while involved in the two calls and connect the remaining two parties in a two-way
connection.
Customer-Originated Trace (COT)
Customer-originated trace (COT) allows users who have been receiving harassing or prank calls to
activate an immediate trace of the last incoming call, without requiring prior approval or manual
intervention by telephone company personnel. After an harassing or prank call is terminated, a user who
wishes to trace the call goes off hook, receives a dial tone, and dials the COT activation code (*57). When
the trace has been completed, the user receives a COT success tone or announcement, such as, “You have
successfully traced your last incoming call. Please contact your telephone company for further
assistance.” (Information about a traced call is made available to the telephone company or to a telco
designated agency, usually law enforcement, but not to the user who initiated the trace). Because COT
is activated on a per-call basis, the service is deactivated when the user goes on hook.
Do Not Disturb (DND)
The do not disturb feature is activated and deactivated by the user. It routes calls destined to the user’s
DN either to a special do not disturb announcement or to a special tone. A user can dial the activation
code (*78) to enable this service, and dial the deactivation code (*79) to disable the service.
Hotline Service
Hotline service is a dedicated private line between a subscriber phone and a predetermined DN. The
service is activated by the service provider at the request of the subscriber. When the hotline user picks
up the phone, the Cisco BTS 10200 Softswitch rings the predetermined DN instantly. Only the service
provider can deactivate hotline service.
Interactive Voice Response (IVR) Functions
The Cisco BTS 10200 Softswitch supports interactive voice response (IVR) functions for activation of
remote call forwarding (RACF) and screening list editing (SLE) features.
Multiline Hunt Group (MLHG)
A multiline hunt group (MLHG) is a telecommunications channel between two points, such as a
telephone company CO/switching center and a call center, PBX or key system. Typically, a business has
more stations (telephones) than lines, and hunting features allow sharing of a group of lines by many
individual stations for both incoming and outgoing calls. Hunting refers to the process of a call reaching
a group of lines. The call tries the first line of the group. If that line is busy it tries the second line, then
it hunts to the third, etc. A hunt group is simply a series of lines organized in such a way that if the first
line is busy the next line is hunted and so on until a free line is found. Often this arrangement is used on
a group of incoming lines. Each line in a MLHG has a terminal number that identifies its position in the
group.
