Google Talk is an IM client XMPP protocol and VoIP (like Skype) that was developed by Google. The beta version of Google Talk released on August 24, 2005. Google Talk supports interoperability protocol under Jabber / XMPP, which is configured in a program such as Psi, Miranda IM, iChat and Pidgin (formerly Gaim), among others. To be able to connect XMPP client TLS encryption and SASL PLAIN requires authentication over port 5222.
This service is available for users of Gmail. Registration is currently open, and you can get an account go to gmail.com. The fact that Google has been used according to the XMPP protocol has been great news for many people who think that this will serve to expand and increase the performance of XMPP.
Protocol that Google has been developed for voice communication, Jingle, has been freed from the beginning, so that clients can include. Psi and Pidgin are planning to include it.
Users should be aware that this program is in beta and is still in development stage, without presenting all the features and functionality of the final version. In addition to possible errors in the latest features that can be added.
One alternative to the Google Talk Gmail Chat is to use the same network but does not need to install or download any software as the user speaks through the browser when viewing your mail. This original web chat has convinced all users and is already being tested in other mail such as Yahoo! Mail and Windows Live Mail is considering adding this option.
