Users can send instant messages to other Gmail users. As it works within a browser, Google Talk does not need to be downloaded to send instant messages to Gmail users.
Conversation logs are automatically saved to a Chats area in the user's Gmail account. This allows users to search their chat logs and have them centrally stored in their Gmail accounts. It does not, however, appear possible to download chat logs that are not attached to an e-mail conversation.
The connection between the Google Talk client and the Google Talk 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.
Google added voicemail and file sending capabilities to the Google Talk client. Voicemail messages can be 10 minutes long, and they're delivered to the contact's mailbox as an attached MP3 file (11 kHz mono 24kbit/s). Recipients who use Gmail are offered better integration. Gmail recognizes that it is a voicemail message, and users can choose to stream the file using the integrated MP3-playing applet, or to download the MP3 file.
This feature 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.
