Take a look on new fresh version of redesigned online chat plugin

Good Morning
here in Brazil, people also use the Offline Chat, where if the user is online the conversation is started instantly, and when he is offline he receives a text message consenting to the message in a single place in OSCLASS,

I ask: how do I make the chat available offline.

thanks.

I recommend to use Instant Messenger instead:
