Hi, we are using SEMS as an SBC in almost all of our deployments and we are actually quite happy with it. We originally sponsored the development of the Transcoding capabilities in SEMS (with the condition of making it open-source) and we added Transcoding for the AMR-NB codec in our branch of SEM

Daniel, I'd be curious to know if you have any thoughts on this, although it is of course a very controversial idea. My personal philosophical position is very much against it. It's just not what Kamailio is. However, I see demand for it _everywhere_. -- Alex Balashov | Principal | Evariste

Would the proposed B2BUA be based on dialog module? If so, I remember a few years ago that there were some fundamental problems with dialog module and it was proposed to design a new dialog-ng module. I haven't followed what (if anything) happened. Would the proposed B2BUA also include SBC style

Hi, I wanted to raise the possibility of an inline signalling-only B2BUA component to Kamailio. I know that's an extremely poor fit for Kamailio, and not at all what it's supposed to do. And there are many things about the OpenSIPS B2BUA module that reveal how awkwardly it is situated, as a
