<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>we are
considering OpenSER for offering free SIP-based voice, video and IM services and
I am trying to get an idea of the project cost.</SPAN></FONT></DIV>

<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>The
components we need are:</SPAN></FONT></DIV>
<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>- SIP
stateful proxy + registrar server</SPAN></FONT></DIV>
<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>- location
& presence server</SPAN></FONT></DIV>

proxy for symmetrical NAT traversal</SPAN></FONT></DIV>
<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>- (perhaps
I forgot something here?)</SPAN></FONT></DIV>
<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>We'll rely
on external gateways for PSTN access so that is not to be taken in consideration
here.</SPAN></FONT></DIV>

face="Trebuchet MS" size=2><SPAN class=873181612-27102005>In other words, how

</SPAN></FONT><FONT face="Trebuchet MS" size=2><SPAN

<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>- operating
system: Linux</SPAN></FONT></DIV>
<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>-

<DIV><FONT face="Trebuchet MS" size=2><SPAN class=873181612-27102005>I also have
a second question: which organisations in Europe offer commercial support for
OpenSER?</SPAN></FONT></DIV>
