The Asterisk-Java package consists of a set of Java classes that allow you to easily build Java applications that interact with an Asterisk PBX Server. Asterisk-java supports both interfaces that Asterisk provides for this scenario, The FastAGI protocol and the Manager API.
Asterisk-Java is compatible with Asterisk 1.0 and 1.2. The FastAGI implementation supports all commands currently available from Asterisk.
The Manager API implementation supports receiving events from the Asterisk server (e.g. call progess, registered peers, channel state) and sending actions to Asterisk (e.g. originate call, agent login/logoff, start/stop voice recording).
Enhancements:
- This release has full support for Asterisk 1.4 and the new Live API (org.asteriskjava.live).
- The Live API takes care of the low-level action and event handling of the Manager API, and offers an intuitive API for Java developers.
- Asterisk-Java takes advantage of the features of Java 5.0, and therefore requires a Java Virtual Machine of at least version 1.5.0.

Asterisk::LDAP is a perl module for generating Asterisk 1.0 compatible configuration files from an LDAP directory tree.
The package includes everything you need to get started, including the module itself, schema files, and example code.
Functionality is provided to see if a reload is necessary and optionally send asterisk a reload command when updates are made. Included is a script that can be called from voicemail.confs externpass option to update a users voice mailbox PIN number in LDAP.
Asterisk::LDAP is currently capable of generating extensions.conf, voicemail.conf, and musiconhold.conf. Support is planned for sip.conf, iax.conf, and meetme.conf.
Enhancements:
- Contexts are now written with a serial number and are not updated unless the serial number is incremented.
- This allows for granular and guaranteed consistent updates.
- The API has been dramatically cleaned up.
- Where before a number of calls were required to set up before getting any useful data out, only one call is required and three more optional calls can help automate most of the configuration.
- The developer may now choose to read the information from LDAP or write the contents to a set of files or to access the internal data structures directly for manual formatting.

Asterisk Live CF card is, clearly, a compact flash install of asterisk that will give you a complete, running system similar to that of the asterisk live CD.

Indeed most things are the same although there have been some additions and changes.

To install the CF you will need some way of getting the image onto the card. Generally this can be done with a USB CF card reader using

dd if=asterisk-cf-b01 of=/dev/sda bs=1k count=64000

Useful things to know

1. The cf install currently assumes its hda (1 2 and 3) so youll need to put it in as your primary master using your CF->IDE adaptor, this will be more automagical in the future

2. example configs are stored on hda3 along with a new feature script called remoteconfig. This will allow you to update the configuration/OS automatically on boot from a remote webserver. More detail on how to use this feature will appear at http://www.automated.it/asterisk be sure to read any notes there first.

3. At the minimum youll need a 64mb CF card but you can use a larger one if you wish and create futher partitions. Currenly when you create the CF from the image the following partitions exist

Disk /dev/hda: 8 heads, 32 sectors, 490 cylinders
Units = cylinders of 256 * 512 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 33 4208 83 Linux
/dev/hda2 34 354 41088 83 Linux
/dev/hda3 355 490 17408 83 Linux

4. Once booted you will need to make changes to the files in /dev/hda3/astlive-example, particularly networking and the zapata/zaptel configs. Note, if you rename the astlive-example directory to astlive then on the next boot the files will be copied and activated on the running system automatically. Using the example astlive directory includes a PASSWORD CHANGE for root from EPPING to epping (without quotes) as a demonstration. At the minimum you MUST change the networking to suit your environment, since they will change to what is in this directory too.

5. All partitions on the CF are unmounted after boot so if you need to work on them, you will need to specifically mount them.

6. Ive tested E100P, X100P and TDM40B cards using this install, and would be interested to hear of other cards proven to be working.

Asterisk PBX is Linux based, open source PBX software that provides voice over IP in three protocols and is interoperable with most standards-based telephony equipment using comparatively inexpensive hardware.

If you want to play around with Asterisk check out this distribution which is available as a Live CD and a Compact Flash install.

Voix Manager project is a switchboard application Iax phone integrated, is written in C++ and is able to manage and display information about your Asterisk PBX activity in real time.
Voix Manager has been thought with simplicity in mind, all feature needed by the attendant, fast and easy usable, with the minimum configurations, just fill the phone and manager login information and play.
Voix will be available in two versions Free and on Payment, the Free version is an advanced multiplatform Iax2 softphone, The full on payment version is a full switchboard management application with all the usefull function to do the job, and why not? if you need a powerfull phone this is the right choice too.
Version restrictions:

Enhancements:
- We have added a new template so is now possible to organize the extensions in groups, for every group is possible turn on or off the visibility.
- We have changed the click behavior on the extensions from double click to one click, this is useful for touchscreen users.
- More improvements in the graphic layout and in the tootips, and fixed some bug.

Asterisk-Soap is an extensible SOAP (Web services) API with the goal to create and support all Asterisk configuration features.

Asterisk Soap APIs mainly feature is to provide a framework between asterisk core api and multi-platform frontends.

KObelisk is a tool that connects to the Asterisk PBX and gives information to the user about incoming calls. KObelisk also provides some basic functions like calllists, ringtones or a callback function.

Installation:
1) use ./install.sh (as root) to install after this you will find a KObelisk entry in your menu

2) start the program

3) configure KObelisk by rightclicking on the little KObelisk Icon at the traybar (most important is the Asterisk module configuration)
