I am looking for a website chat system (paid or free) which can be hosted locally rather than through an online service. This tool is going to be used as part of a company intranet system allowing staff to communicate with members of the service desk through 1:1 chat window, which will be accessible through the intranet.
I have tried looking at phplivesupport, which seemed to be what I was looking for. The main issue with this was getting in touch with the company. Since support would be preferable I would like the software to still be relatively active with development/support.
