<DIV>Yes, it will do that. We use opensips for SIP trunking to our
customers and to on-premise and hosted PBXs we sell (Asterisk based).</DIV>
<DIV> </DIV>
<DIV>It is not a trivial task by any means, but you can build a very secure
middle layer with opensips.</DIV>
<DIV> </DIV>
<DIV>We use it to:</DIV>
<DIV>Register SIP trunks to redundant opensips servers, with failover</DIV>
<DIV>Route inbound calls from 30 carriers to the SIP trunks, performing many SBC
type functions as we normalize the SIP headers.</DIV>
<DIV>Perform rewrites of numbers</DIV>
<DIV>handle remote call forwards.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>do Proxy authentication for outbound calls from SIP trunks, doing those
same SBC type functions, plus least cost routing and failover between carrier
gateways.</DIV>
<DIV>do very fine grained control and billing of high rate NANPA and
international calling – not just “turn on international”, but allow/disallow
calls to regions/countries/city codes/specific GNPs. Plus rate limits,
simultaneous call limits and real time blocking based on credit limits</DIV>
<DIV> </DIV>
<DIV>handle very complex call detail recording and billing</DIV>
<DIV> </DIV>
<DIV>SIP trace to database </DIV>
<DIV> </DIV>
<DIV>RTP proxy when client is behind NAT</DIV>
<DIV> </DIV>
<DIV>and...a lot more. </DIV>
<DIV> </DIV>
<DIV>Final note – it is rock solid and very high performance. If you are
not proxying media, you can pump a massive amount of traffic through one
instance of opensips, even if you have it doing a lot of database work as we
do.</DIV>

<DIV>At this point I am considering using OpenSips & OpenSipsCP to run as a
border controller per say.<BR></DIV>I would like to configure and setup the
clients to register the the box, then our box connects it to the back end sips
and handles logging, possibly billing. We install asterisk servers at the
client side so we're not looking for this to play of the role of the
PBX.<BR><BR></DIV>
<DIV>I want to set up 1 first, play with it and see if it's what we would like
to use over other solutions, if so we then want to setup a redundant box, remote
location for high availability.<BR></DIV>
<DIV> </DIV>
<DIV>Does this sound like something that will do the trick?<BR></DIV>
<DIV> </DIV>
<DIV>I would love to get a knowledgeable tech to jump in, I have a squeaky thin
budget for someone interested, please contact me.<BR></DIV>
