Description

The Media IPBX project is based on the Seam Telco Framework and it's goal is to demonstrate the technology and eventually become a real useful PBX product.

The primary design requirements for the PBX are:

To have a dynamic Web GUI where users can log in, manipulate and monitor the call status, adjust system or profile settings and so on
To allow proxy-mode and all other classic PBX operations without the need to use the Web GUI
To be extensible and customizable

Currently the PBX terminates all calls in Mobicents Media Server conference endpoints, which allows maximum flexibility to manipulate the calls after they are established. This allows features like server-side conferencing, ringback tones, later voicemail and call recording will be added. Another application of the PBX is to act as Session Border Controller. For now the PBX runs only on Mobicents Sip Servlets with JBoss AS 4.2.3

Features

The most notable features currently implemented in the PBX are the following:

Registration, login and configuration from the GUI
Call monitoring and management from the individual user views
Users can have multiple phones and switch between them from the Web UI (call parking), they can assign phones that are active or unactive (ringing or not when calls are coming)
Calling multiple users in a conference by making normal calls
Call control from the Web UI - mute, close calls and others. Audio announcement is made to the affected users.
Incoming calls can be joined in an active conference or rejected
Ringback tones when waiting for the other participants in the call to join
PSTN phone calling with PSTN admin functions
Audio notification sources (wav files) and other options configurable from the administrator account
Putting users on hold and isolating a single speaker with DTMF when in a conference (experimental)
Automatically adding phones for users using the SIP REGISTER request by matching the username or username and hostname (in strict mode)

Note that most of the announcements and tones are being downloaded from the internet at runtime by default. Depending on your internet connectivity you an experience delayed announcements or ringback tones. If you want to improve the response time you can configure local files used in announcements from the configuration panel.

You can find a lot of other smaller features in the IPBX. Many of them are explained in the hints that appear on the web pages. You can see a few demonstrations on YouTube:
