Hi all,  
I’m new to this project.

This project looks fantastic in design choice comparing the FreePBX, but also different from the Kazoo project in the design choice  
My question is does the Wazo has first-class support for SBC?  
I see that the the [wazo-c4-sbc](https://github.com/wazo-platform/wazo-c4-sbc), [wazo-c4-router](https://github.com/wazo-platform/wazo-c4-router), and the wazo-rtpe-config are not maintained anymore.  
Are they supported?

Best regards,  
Menashe

Hello,

For the moment we maintain only the class 5. Class 4 is currently not maintained.  
But contribution to help on this project is welcome.
