Topic: Call control


  
  Out-of-band - Wikipedia, the free encyclopedia
In telecommunication, out-of-band communication is the exchange of call control information in a separate band of the data or voice channel, or on an entirely separate, dedicated channel (as in Common Channel Signalling).
The term is sometimes used to describe what people in the communications industry call "shift characters", such as the ESC that leads control sequences for many terminals, or the level shift indicators in the old 5-bit Baudot codes.
In personal communications, methods other than e-mail (such as telephone or snail-mail) are called "out-of-band".

 An Introduction to Telephony Call Control with Microsoft Speech Server 2004
During the consultation call, the original caller is placed on hold at the consulting device (D1), and a new call (C2) is initiated to the consulted device (D3).
After the consultation call is connected, the consultation call service request completes, and the new call (C2) is in an active connected state between the consulting device (D1) and the consulted device (D3).
For most extended call control functionality, including supervised transfers and conference calls, the CSTA Consultation Call service is crucial, and understanding how it works is imperative for the developer who wants to exploit extended call control.

 VoIP Call Admission Control
An increase in postdial delay exists for the first call only; information on the destination is cached after that, and a periodic probe is sent to the IP destination.
If the design objective is to limit the maximum number of calls between sites (rather than protecting the bandwidth of the egress WAN link), this is very suitable feature to use, provided the dial peers are structured in such a way that each remote site has one dial peer pointing calls to it.
As shown in Figure 9, when a call is attempted at the outgoing gateway, the network congestion values for the IP destination will be used to allow or reject the call.

 call control - a Whatis.com definition
Call control is a process that is used in telecommunications networks to monitor and maintain connections once they have been established.
In a VoIP network, call control is one of three major categories of communications traffic, the other two being call signaling and media communications.
Call control functions include, but are not limited to, the determination of master/slave status for the endpoints, monitoring of the status of the endpoints, modification of the parameters of a connection, termination of a connection, and restarting a terminated or failed connection.

 About Call And Media Controls [TAPI 3.1]
TAPI 3 call and media controls are a generic set of COM objects, interfaces, and methods for making calls between two or more machines.
The five main objects in the TAPI 3 call and media control architecture are TAPI, Address, Terminal, Call, and CallHub.
The diagram in About Call And Media Controls shows these objects with their associated interfaces and is hyperlinked to the object overviews and the interface reference section.

 Call Control Function   (Site not responding. Last check: 2007-10-31)
Call progress involves the detection of several events (e.g., signaling, tones, voice) received from the network and the remote party.
This section provides a description of a call's progression, the events generated by the network, and the application of those events to AG Access' call control.
The application specifies in the call control parameters whether to generate a connected event under this condition or to abandon the call and generate a disconnect event as shown below.

 Call Control
The request to setup a call may be unsuccessful due to various factors, such as failure to receive a specific TUP message or dual seizure.
In such a case, the call accepted is the one being processed by the controlling side and the call being processed by the non-controlling side is given up.
The call is not released immediately at the calling side to allow for the possible reception of a re-answer signal as shown in “Re-answer Procedures”.

 VoiceXML Review - Feature - Using Call Control XML (CCXML) as a SIP Softswitch
CCXML is a sibling standard to VoiceXML, designed to facilitate enhanced call control capabilities in both VoiceXML platforms and in call control platforms that have no relationship to or with VoiceXML.
All of the call control and call routing in this environment is driven by the CCXML platform, which is in turn driven by CCXML documents from one or more web servers and via event input from various CCXML Event I/O processors.
In this case the Softswitch is responsible for routing calls to their proper destination based on embedded routing rules and using an external database driven directory.

This call control guide is designed to help application developers and system integrators understand and use the API provided by Aculab for use with Aculab digital access cards.
API calls that perform global initialisation and/or querying (most of which are in the version 5 (V5) Call API) have been replaced by API calls that work on a per-card or per-port basis.
This guide should be used with Aculab call control driver Version 6 or later, for the development of applications that initiate and control outgoing calls and receive and control incoming calls.

 Java Call Control, Coordination, and Transactions
While there are important differences among these call models, reflecting the architecture or application for which they were intended, their overall goal is generally similar: to initiate, control, and manipulate calls, and to facilitate the development of applications that execute before, during, or after a call.
When call processing reaches a state in the FSM where a trigger is defined and enabled, processing is suspended and a program (called service logic) executing at a remote network element such as the SCP is invoked; call processing is resumed once the service logic completes execution.
The state of a telephone call is maintained by finite state machines associated with Call, Connection, and Terminal Connection objects (e.g., when a call is answered by the called party, the originating Connection object moves to the CONNECTED state).

 Call Control Requirements in a Voice Browser Framework
The scope of these language features is for controlling resources in a platform on the network edge, not for building network-based call processing applications in a telephone switching system, or for controlling an entire telecom network.
The activities of the Call Control Subgroup will be coordinated with the activities of the Dialog Subgroup (both of which are part of the W3C Voice Browser working group).
This may mean by using information provided by the network when the call is presented (inbound call number, caller identification information, and so forth) or based on a user interaction for instance in the caes of call waiting.

 Voice Browser Call Control: CCXML Version 1.0
The Telephony Control and Dialog Control Interfaces may be implemented as an API or protocol.
The CCXML specification originated from the desire to handle call control requirements that were beyond the scope of the VoiceXML specification.
In order to accommodate the widest range of underlying telephony call control definitions, CCXML assumes a separate Conference Object, realizing that this abstraction may not have a direct counterpart in all telephony platforms.

However, in order to build applications that move the caller across a telephony network, call control is necessary.
The connection object is agnostic to whether the call was originated by the caller or the platform.
Now that the VoiceXML 2.0 language call model is agnostic to whether the call was placed by the platform or arrived from the caller, we need a standard way to request that a platform place an outbound call.

Remaining calm is important because it results in rational thinking and a constructive response, which permits a call center agent to seize control of a service event.
Minimizing call center stress begins with rational thoughts about what is within an agent's sphere of control.
Since call center agents can not control the weather, traffic, equipment failure or a customer's behavior, then the focus must be emphasized on things which are within the call center agent's sphere of control.
