Full Source Code

A full C source code release allows InstaV2IP Embedded to be used on virtually any platform. Simply porting the Fusion Common Layer (FCL) abstraction to a platform’s RTOS/OS, network stack, and file system (optional), and implementing audio/video driver channels for the platform’s audiovisual hardware is all that is necessary to start making voice & video calls. Additionally, having full source code allows customer changes to be made to the code (such as implementing newer or less popular RFCs) and aids in debugging low-level problems.

InstaV2IP Embedded Features

Call Manager

Call Manager is the logical bridge among the VoIP layer, Voice Engine (VE) and the User Interface (UI). Fusion Call Manager effectively handles all incoming calls, outgoing calls, call transfer, call hold, call conference, etc. It processes the requests from the VoIP layer and User Interface, while controling the state of the Voice Engine as required.

• Actions: place calls, answer calls, disconnect calls, on/off hold, transfer, conference, generate DTMF, etc.
• Events: incoming call, peer on/off hold, peer disconnect, being transferred, DTMF received, registered/unregistered, etc.
• Call manager control via HTTP/JSON-based web service for remote control
