Reference10:Concept myPBX

Overview

myPBX is the UC client of the innovaphone PBX. It is intended for assisting typical phone users with their everyday tasks. It consists of two parts:

• A web application that runs in any modern web browser. It provides the functionality needed for audio teleophony, instant messaging, monitoring peoples statuses and more.
• The myPBX launcher. It's a Windows application that integrates the myPBX web application into the Windows desktop and adds some interesting additional features like video telephony and Outlook integration.

Web application

The main user interface is an HTML5 application that runs in a web browser. It communicates with the PBX using HTTP-Requests (AJAX). The actual session logic is implemented inside the PBX.

The picture shows how call control is done. The myPBX session has access to the phone registration as they are both located in the same PBX. Thus it can monitor and create or modify calls.

myPBX launcher

The launcher is a tool for integrating myPBX into the Windows desktop. It is not needed in order to use myPBX but it adds some convenient functions that are not available otherwise.

• Automatically open the myPBX web application on startup.
• Desktop notifications.
• Video telephony
• Office2010 Integration
• Hotkey for dialing numbers out of any Windows application.
• Set the status depending on user activity.
• Switch to a standby PBX if the main PBX is down.
• Write trace files.

Requirements

PBX

• myPBX license
• Reporting license (for seeing recent calls in the history)

Web browser

• Current version
• JavaScript enabled
• HTML5 XMLHttpRequest (AJAX) enabled
• HTML5 Web Storage (DOMStorage) enabled
• HTML5 Cross-document messaging (postMessage) enabled

Note: The launcher always uses Microsoft Internet Explorer for opening the web application. It does not use the configured standard browser.

• Windows 7
• .NET 4

Related technology

• myPBX uses the innovaphone Reporting as a database for call lists.
• The Exchange Calendar Connector sets the presence of PBX users depending on their Exchange Calendar. myPBX can display that presence.

Appendix

Network traffic

In idle state the web application needs an empty message exchange every 30 seconds in order to keep the session alive. This messages take about 800 bytes. So per session the minimum network traffic is approximately:

• 1600 B/min
• 94 kB/h
• 2.2 MB/d
