Newbie question: that's if all the audio is passing over the server's
bus, right?

I'm looking at a pretty big system using either SIP or MGCP to tell a
bunch of FXS and T-1 media gateway boxes to talk to each other over a
dedicated GigE -- would that *be* a reinvite situation, generally, or
not?  I'm assuming that since the server would only be doing MoH, VRX,
and the like, that I'm in much better shape loadwise, even at 40xSIP +
390xFXS.
