I am searching for a support system for a small team of around 10 users. The features that I would like are:
Integrate with our website so that users can log and create/update support requests;
Create groups for support requests;
Real-time instant messaging;
Mobile phone app;
Used with a support email address;
To be installed locally;
I have tested many systems but cannot find a system with all these features. I am looking for something that we can host and pay an annual support fee for.
Any help and suggestions would be great.
