If an agent is not available or cannot answer, then you can notify a user and forward them to a web page you select.

Real time translation allows visitors and agents to chat to each other in different languages. ParaChat LiveHelp can translate the chat text in real time in both directions. ParaChat LiveHelp can currently translate to and from the following languages:
English, German, Spanish, French, Italian, Portuguese, Russian, Greek, Dutch, Swedish, Japanese, Chinese (Simplified), Korean, Arabic
Real Time Translation is an optional premium feature. The actual translation is performed by a web service, which you need to subscribe to. You must purchase translation 'credits' and setup a translation account before translation will work. To purchase translation credits, please visit:

To enable translation for a specific monitored site, select the Visitor Chat tab on your Site Properties. Then select the Translation tab. Select the Enable Chat Translation option. You must then enter your Translation Server Account User Name & Password. Select the Default Agent Language - this is the language used by agents within your organization. Your Translation Server Account User Name & Password will be issued to you after you purchase translations credits.
Once translation is enabled then whenever a visitor starts a chat session, ParaChat LiveHelp reads the visitor's language from their browser settings (or the &lang= parameter of the chatstart querystring). If the visitor's language is different from the agents language then the visitor will be asked if they want to chat in their own language. If the visitor chooses to chat in their own language, then any chat text that the visitor sends will be translated into the agents language.
At the agents end, the agent has a choice of disabling translation for the chat session. The agent can also choose to send text that will be translated or not.
For both the visitor and the agent, the original and translated text is show and stored in the chat transcript for future reporting.

If the visitor's language does not match the agent's language, then the visitor will be asked if they would like to use translation.

Once in chat session, the visitor will see both the original and translated text.

The agent can switch off translation, and select to send un-translated text.
The agent also sees both the original and translated text.
ParaChat LiveHelp uses 'machine translation'. Which means that the text is translated by a computer. The result may not be an accurate translation, but should be enough to give the 'gist' of what each party is saying.
