I’m not sure what you want, since this is a demand and not a question.
The SCCP manager I wrote for Asterisk 1.8 and FreePBX “a heck of a long time ago” was completely obsoleted by the new FreePBX BMO data model. Between that and the new style sheet implementation, the SCCP Manager is no longer viable or supportable. In addition, there are some significant security flaws in the implementation of the original code that made it “unfriendly” for newer versions.
I don’t have time to maintain it right now, which would mean completely rewriting it and learning an entire new development framework. I’m busy with lots of other stuff, and frankly, the information on the Chan-SCCP-B Wiki that I wrote about implement the channel driver is 90% of what you need. If you follow the recommendations on there, you should find that you don’t actually need a GUI interface.
