Feedback - SBC Vendors.

I am going to have to install a series of SBCs for a voice offering connected to Microsoft Teams. We are going to pass the SIP traffic off to a larger number of SIP providers. I would like to get some feedback from the group on SBC vendors. I have two options for vendors Ribbon or AudioCodes. I am leaning towards a software based SBC over an appliance. Would be helpful to get the other members feedback on Ribbon or AudioCodes deployments within their networks. Cheers Ryan
