It also means you can start thinking about instant communications in a new way.  Google Talk offers you different ways to integrate real time communications into your online experience.  The Google Talk Gadget lets you see who's online and send instant messages from your Google Personalized Homepage, without installing any software.  You can also add the same instant messaging capabilities to your own webpage or blog by cutting and pasting a single line of code.  And by downloading the Google Talk Client, you can make voice calls and transfer files to your friends.

And if you use Gmail, Google Talk offers you even more.  You'll find all of your Gmail contacts organized in your Talk contacts list.  Gmail also archives all of your Google Talk chats and makes them searchable.  And since Google Talk is integrated into Gmail, you'll be able to chat with all your Talk contacts there, too.

Asterisk® supports Voice over IP in many protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware.

Free PBX

FreePBX is a Standardised Implementation of Asterisk that gives you a GUI to manage your system. If you’ve looked into Asterisk, you’d know that it doesn’t come with any ‘built in’ programming.

FreePBX simplifies this by giving you a pre-written set of dialplans that allow you to have a fully functional PBX pretty much straight away.
