We have a helpdesk which at the moment accepts only phone calls and emails, which is a little problematic when we need to request a lot of technical information step by step. We have a lot of systems which log everything, and do not want an all in one solution.
We need a simple, highly customizable chat which we can integrate with all of our systems, aka code which is easy to read/modify. I am developing everything in PHP, and would like a solution which uses PHP and MySql. I have looked at PHP Live!, which does everything that we want it to do, but it is not free.
Does anyone know software which will do this, but without a price tag?
