<p class=MsoNormal style='margin-bottom:12.0pt'>If you plan to transcode g729
to g711 it will impact performance dramatically but you should still get a few
hundered channels up on a nice server box. You could contact <a
href="mailto:consulting@freeswitch.org">consulting@freeswitch.org</a> about
g729 license options.<br>
<br>
With no g729 you could scale a nice 8 core box into a few thousand channels
pushing rtp.<br>
<br>
Do you have a requirement to transcode g729? you could just use g711
right from the phone couldn't you?<br>

<p>2.<span style='font-size:7.0pt'> </span>We
are using sipX as an open source PBX. We’d like to use FreeSwitch purely as a
B2BUA for connectivity to the PSTN. Our Polycom phones use SIP REFER messages
to do call transfers and our ITSPs can’t handle those. So, we’ve tried the
“under the hood” FreeSwitch within sipX. It works for many applications but we
need to scale a unified system for larger customer deployments. If we want to
create a trunk to an ITSP and a trunk to an internal PBX, would we use the
external gateway XML files for both? We don’t plan to point any internal phones
to the FreeSwitch box (we’re using sipX as an internal PBX). <o:p></o:p></p>
<p>3.<span style='font-size:7.0pt'> </span>If
we use multiple ITSPs, can we assign a priority to each one, so one will be

<p>4.<span style='font-size:7.0pt'> </span>I
understand no performance metrics are posted. Can anyone share their
experiences with passing RTP through the server? Does RTP affect performance in
a big way (very open ended question, I know). We are looking for ball park
answers so we’ll have some idea of scalability for our designs. <o:p></o:p></p>
