The Global Call development software provides many features allowing for the development of 
flexible and robust applications. The features fall into one of two main categories: 

 

 

The Global Call development software provides the following call control features: 

Basic Call Control 

Includes basic call control features such as, the ability to make a call, detect a call, answer a 
call, release a call, etc. The implementation of these capabilities is based on the basic call state 
model, which is a common model for all network technologies. See 

 for more information on the basic call model.

Advanced Call Model 

Defines the behavior for advanced features, such as hold and transfer. These capabilities are 
provided to support technologies and protocols that support such features, for example, 
Supervised Transfer. The implementation of these capabilities is based on a more advanced 
call state model. See 

 for 

more information. The advanced call model applies only to E1/T1 and ISDN technologies, not 
IP technology, which uses a different scheme for features such as call transfer. See the Global 
Call IP Technology Guide. 

Call Progress and Call Analysis 

Provides the capabilities for handling pre-connect (Call Progress) information that reports the 
status of the call connection, such as, busy, no dial tone or no ringback, and post connect (Call 
Analysis) information that reports the destination party’s media type, for example, voice, 
answering machine, or fax modem. This information is determined by the detection of tones 
defined specifically for this purpose. See 

 for more information. The call progress and call analysis 

feature applies only to E1/T1 and ISDN technologies, not IP technology. 

Feature Transparency and Extension (FTE) 

Provides the ability to extend the capabilities of Global Call to handle features that are specific 
to a particular technology so that those features are accessible via the Global Call interface. 
For example, for ISDN applications, Global Call supports supplementary services such as 
Overlap Send, Overlap Receive, Any Message, Any IE, and User-to-User messaging. See 

 for more information.

The Global Call development software provides the following features that facilitate the operation, 
administration and maintenance of Global Call applications:

Error Handling Functionality 

When an error occurs, Global Call provides functions that enable an application to retrieve 
more information about the error. See 

 for more information.
