Thank you, Gordon! Yes, MS RTC is just SIP streams of alaw.

I don't know anything about MS RTC.. But if it's just SIP streams of alaw, then a rough guide is that you'll need 80Kbits/sec per stream. So 30 streams on a Gb network will barely be noticable over the usual background noise ... And each PC running a single stream will be just fine. The asterisk server will be seeing an aggregate bandwidth of (30*80*2)Kbits/sec, or 4.8Mbits/sec. Hardly anything to wory about. I have Linux routers based on 1Ghz processors that can sustain 20x that traffic, and a 1GHz processor running asterisk would easilly support double that number of connections, so any modern "server" type PC should be fine for your use.
