Which HelpDesk system to choose for integration into the corporate portal?

Question

CodeIgniter

What is the essence of the issue, there is a choice between developing a HelpDesk system or integrating it into an existing corporate portal. What is the complexity of development? Since I’m not quite an experienced developer, I had to look at ready-made solutions, maybe borrow some developments and ideas, the TOR is more or less drawn up, but they ask to develop the system on Codeigniter.
Requirements for the system:
- Applications can be sent both to a department, such applications are open, any employee of the department can take it and see the whole department, they can be distributed, then only the head of the department and the person in charge can see them.
- SMS/E-mail alerts
- Distribution of tickets on issues, since the company has full users, they easily send requests to change the cartridge for web development. So I would like something like leading questions when choosing a topic, and the ability to customize distributions, because. there is no dispatcher.
It seems that the basic requirements for the system, at the moment there is OSticket, but on a separate web face, on the corporate portal through the domain, like users are used to it, so I would like similar functionality, and expand a little, which is still easier, take the finished system and finish it for yourself, or develop a system with the necessary functionality.
