Layer 4 Call Control Overview

Introduction

Call Control lets you create unique call models, with custom definitions of call routes and control parameters, and to implement them quickly. You can build into the model PBX-like features, such as one- and two-way connections, call parking, and call hunting, then automatically execute them.

Call Control allows many aspects of a call model to be executed in the CSP, simplifying host applications and improving performance.

Features

Call Control features include:

• Connection Management

• PPL Technology: Call Control uses Dialogic’s Programmable Protocol Language (PPL) technology, simplifying application development, customization, and debugging

• DSP Resource Management: To reduce host interaction, you can preprogram Digital Signal Processors (DSP) resource management (except for conferencing) into the call model

• Call Routing: The Routing features allows the CSP to route calls based on defined criteria or preconfigured settings, without host intervention.
