I think I'm not making myself clear, sorry. Our t3's and Megalink circuit from Bell come into AS5400's. Our VoIP infrastructure is entirely SIP. A conferencing server would only handle RTP streams, mixing channels for many large-ish volume conferences. The box I'm talking about would have 2 10gig nics, one or two DSP cards, and whatever software is needed to handle managing conferencing and directing RTP/G.711 content channels to and from the DSP card(s). I am not looking to build a stand alone phone system.
