Pop-up chat type https://www.jivochat.com/

Нужен pop-up chat type that will work on my server for my websites.
I want the man himself jumped out after for example 20 seconds of a person staying on the website and spoke to him on my behalf I called the message on the computer if people would answer me – and we talked with him in chat.
Well, I would like the log of the conversation where either remained, or my e-mail or in the database.

Interested in your price and terms.
