I have an ESI system on which I would like to set up meet-me conferencing. The ESI Comm Server supports SIP clients in the role of SIP registrar which would lead me to believe there is a platform that should work in this application. Does anyone know of one?

I always thought MeetMe was an asterisk thing. ESI has a conferencing engine named that too? Or is that the request, hooking up ESI to Asterisk for MeetMe?

Meet-me conferencing is a legacy feature on many systems, has been for decades, if I am not mistaken. But yes, If asterisk has such an application, that would work. Can you point me in the right direction?
I've also edited my original post to be clearer.
