Multiple PBX's behind SBC

Hi, I am new to SBCs and doing reading and research as I am looking at some POC ideas. (So be kind

Is the following possible:
I have 4 Yeastar S Series IP PBXs which I will want to host at local DC. Each will have their own local IP (192.168.0.10-14)
And each will have their own trunks to a service provider. There will be remote extensions for each PBX.

Would a single SBC be able to manage the trunks and the extensions connecting?
Also is what I am trying to do secure and doable.

Thanks in advance

Hi

Thanks for contacting us from the forum site. You can connect many IPPBXs to ProSBC. Each of them can have its own SIP domains and trunks. Please check SBC Use Cases

Thank you, I saw that after I posted.
