Hi,
First of all congrats for the work, I've been testing over this week and it has been really nice to stress it. I have two questions:

1- It would be really nice to see an OCS integration, is it possible to connect the PCRF and PGW with it? I believe this would be done by a 127.0.0.X IP, right? Is this something simple to implement? It would be nice to check the support to OCS

2- I believe you are developing NB-IoT support as part of your roadmap, what are the main challenges you see in this task? Is it just programming the messages of NB-IoT? Or is it something else? I can try to help you with this task.

Best regards,

Daniel
