<p class=MsoNormal>Hi,<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>I work for a VOIP service provider, and have been tasked
with optimizing our infrastructure.  We have been providing VOIP services
to our clients via Asterisk VM’s (PIAF) in an ESXi environment, hosted in a
datacenter.  We are looking for some kind of SIP Router, which would
authenticate clients and route their SIP traffic to the appropriate
server.  By doing so, we are hoping to further secure our infrastructure
and to possibly have only one Public IP (which would resolve to the Private IP
of the SIP router).  The Asterisk servers serve
IVR/RINGGROUPS/OUTBOUNDTRUNKS/INBOUNDROUTES/OUTBOUNDROUTES.  The Sip
Router would therefore route all SIP traffic between the phones and the
Asterisk servers, ad the phones would register to the SIP Router.  I have
tried many solutions (Kamailio, OpenSER, siproxd, Brekeke), but have not been
able to configure these services to work the way we want them to.  I am
including a chart along with this email to outline what we would like to
accomplish.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Any suggestions or guides would be immensely appreciated.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Thank you all for your time. <o:p></o:p></p>
