VoIP/instant messaging client
Talk (also known as
Google Chat) was an instant messaging
service that provided both text and voice communication. The
instant messaging service is colloquially known as "Gchat", "Gtalk",
or "Gmessage" to its users.
Talk was also the name of the client applications previously
Google to use the service.
Talk applications were
available for Microsoft Windows, Android, BlackBerry, and
Chrome OS operating systems. A
Talk mobile web app had also
been previously available. In February 2015, the Windows client was
discontinued and ceased to work, with
Google recommending users to use
Google Hangouts instead. Users of Windows client were
instructed to migrate to the
Google Hangouts app on the Chrome browser
platform. It remained possible to connect to
compatible third-party apps such as Pidgin and Gajim.
Google dropped support for

corporations and individual users."

In May 2013,
Google announced its plan to drop support for the open
XMPP standard in favor of proprietary
Talk was integrated into
Gmail where users could send instant
messages to other
Gmail users. As it worked within a browser, the
Talk client did not need to be downloaded to send instant
Conversation logs were automatically saved to a "Chats" area in the
Gmail account. This allowed users to search their chat logs and
have them centrally stored in their
Gmail accounts. For a long time,
it was not possible to directly download chat logs that were not
attached to an email conversation, although some workarounds
had been found. However, on September 15, 2011, Google
announced a new feature of its
Google Takeout program that allows
users to download chat logs via IMAP.
Google also integrated
Talk with Orkut. This enabled Google
Talk users to interact with registered
Orkut users, by sending and
receiving "scraps" within Orkut.
Orkut has since been shut down.
Talk Gadget is a web-based module that may be embedded in
Google and other web pages, allowing text chat with users of Google
Talk. Note: this functionality has recently been discontinued
without any real announcement, likely in the face of the release of
Google Hangouts services.
Google+ is integrated into
Google Talk. In the standalone client and
Talk widget embedded into
Gmail and Google+, Google+
contacts appear in the contacts list; their respective circles are
shown in Google+'s iteration of the widget.
Voice and Video
It is possible to place and receive phone calls from within
Google Talk. In order to receive calls, however, the user must
upgrade to a full
Google Voice account. Initially, users outside
of the US could not upgrade to a full
Google Voice account or receive
phone calls in Gmail. (Outbound calling through

whether or not they are signed into
Google Talk. Messages can be
up to 10 minutes long and users can choose to have them sent to their
Gmail inbox. Messages can be sent with or without first ringing the
recipient's phone number.
Google also provides a Voice and Video Chat browser plugin for Google
Talk (not to be confused with the standalone
that supports voice and video chat between
Gmail users. The plugin
is available for Windows (XP, Vista, and 7),
Mac OS X

Intel-based Macs), and

packages available, but the binaries work on other systems). The
plugin must be downloaded and installed, but otherwise seamlessly

The connection between the
Talk client and the
server is encrypted, except when using Gmail's chat over HTTP, a
federated network that doesn't support encryption, or when using a
proxy like IMLogic. End-to-end messages are
Google plans to add support for chat and call encryption
in a future release. Some
XMPP clients natively
support encryption with
Google Talk's servers. It is possible to have
end-to-end encryption over the
Talk network using OTR
(off-the-record) encryption using other chat clients like
Mac) or Pidgin (for
Linux and Windows).
Google's version of "Off the Record" is not OTR (off-the-record)
encryption. Enabling "off the record" inside Gmail's Chat turns off
logging of messages, but does not enable encryption.
On October 31, 2006,
Google introduced offline messaging to Google
Talk. This allows users to send messages to their contacts, even if
they are not signed in. They will receive the messages when they next
go online even if the user who has sent it is offline. This only works
between Gmail-accounts though, and doesn't work between
servers and other
Mobile device compatibility
On June 30, 2006, Nokia released new software for their Nokia 770
Internet Tablet, that included
Talk as one of the compatible
VoIP clients, because of the XMPP-based software. Another Google
Talk-compatible device is Sony's mylo, released on September 15, 2006.
Talk client is also available for
BlackBerry devices from the
Talk support is also integrated into
Google Android devices, but does not support voice and video calls
below Android version 2.3.4. This was released in April 2011 for the
Google Nexus S.
However, given that
XMPP protocol, most mobile
phones for which a suitable
XMPP client exists could also offer
Talk service, at least theoretically (depending on the handset,
the user may encounter security warnings because of unsigned Java ME
MIDlets or limits put in place by the mobile service provider). Mobile
clients specially designed for
Talk exist as well.
Most phones support the IMPS protocol, and there are hybrid XMPP/IMPS
XMPP transports, or specially designed hybrid
servers), which can also contact
Talk users. The Google
Talk service itself is unusable from IMPS (that means, one cannot log

Talk does not provide the user with a menu for text formatting.
Talk does support some text formatting features
like making text bold and italic. To write a message in bold, a user
should type the required text between two asterisks (*), for example,
*this text would be bold in
Google Talk*. Similarly for making text
italic, one should put text between underscores (_) and for
strike-through in text content, one should put text in between dashes
(-). This only functions in some of the
Google native tools, and does
not always function as expected when received from other

The New York Times
The New York Times reported a rumor of a
Google-branded "communications tool" service and the Los Angeles
Times provided details. Subsequently, the subdomain talk.google.com
was found to have an active
XMPP server. Two methods of logging
into the server were discovered soon after and the ensuing response by
eager bloggers revealed to numerous others how to log in before the
official release by Google.
On the evening of August 23, many logged-in users using port 5222 to
connect were disconnected and unable to log back in. Users using port
5223 to connect were still able to log in, and at 04:12:52
users received a broadcast instant message from gmail.com, an
apparently official username used by
Google to communicate with their
user base, that stated "The broken link has been fixed. Thanks for
being our first users!" Port 5222-connectivity was found to have been
re-enabled. On August 24,
Talk was officially launched.
On December 15, 2005,
Google released libjingle, a
C++ library to
implement Jingle, "a set of extensions to the IETF's Extensible
Messaging and Presence Protocol (XMPP) for use in voice over IP
(VoIP), video, and other peer-to-peer multimedia sessions."
Libjingle is a library of the code that
Google uses for peer-to-peer
communication, and was made available under a BSD license.
Google reported that they were working on adding new features
such as supporting SIP in a future release, which would broaden the
userbase for the program.

Google and eBay announced that they would look into
Talk users able to communicate with Skype: "The
companies will also explore interoperability between
Skype and Google
Talk via open standards to enable text chat and online presence."
However, with Microsoft's acquisition of
Skype on May 10, 2011, such
interoperability might have been suspended between

Talk module that can be added to i
Google (formally the
Google Personalized Homepage) or embedded in any web page, thus,
allowing one to chat from any operating system which is supported by
Adobe Flash Player as long as
Adobe Flash Player is installed.
A screen shot was posted on May 18, 2007, as part of the
presentation, showing some phone integration in
Google Talk. On
March 2, 2008. a
Google engineer confirmed they had been using it
internally for some time.
On November 26, 2007,
Talk released Group Chat capabilities.
Before this, users could chat with only one person per window. Group
chat allows many users to chat with each other in an environment
similar to IRC.

of the owner is not revealed to the other peer.
On November 11, 2008,

products, Nikhyl Singhal, stated at
Google I/O that the move to

Talk to interoperate with other vendors and applications) will not be
supported in Hangouts. Mr. Singhal stated that as long as
