We have a CRM system named CD2 which works properly with Chat. Recently our basis team set up another system CD3 of which
the Chat is not working. Upon clicking on Accept button, an error message is displayed "Chat session not connected". The contractor
who set up the CD2 is gone, and I wonder if anyone can help on this error (I suspect something such as queue is not set up right,
but I don't know enough of the Chat to locate and fix the problem)..
