Thanks @Henning, I’m really excited and honoured to actually be in the commit history for Kamailio! That’s a tick off my bucket list for sure.

Thanks @Daniel - I’m very impressed with how much you’re doing at ClueCon, I struggle to get work done at conferences, hope you’re having fun!

The module names show in jsonrpc as lower case, although they are accessed in upper case within the code itself.

I’ve tried with the latest master and my code is running perfectly! It seems this fix worked, thanks!

Cheers
Andrew

>>> Just looked to the app_ruby commits - they are only 10 or so after dev4. Maybe you can just a bi-sect (pick the one in the middle, see if still works, pick the next one in the "new" middle etc..) to find the commit that broke  it for you.

Would it be helpful here for testing if I did this and put in a pull request? I’ll see if I can get that done tonight (I guess today EU time!)
