[OpenSIPS-Users] Basic Question / Concept

[John Scully]

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).

It is not a trivial task by any means, but you can build a very secure middle layer with opensips.

We use it to:
Register SIP trunks to redundant opensips servers, with failover
Route inbound calls from 30 carriers to the SIP trunks, performing many SBC type functions as we normalize the SIP headers.
Perform rewrites of numbers
handle remote call forwards.


do Proxy authentication for outbound calls from SIP trunks, doing those same SBC type functions, plus least cost routing and failover between carrier gateways.
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

handle very complex call detail recording and billing

SIP trace to database 

RTP proxy when client is behind NAT

and...a lot more. 

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.

Subject: [OpenSIPS-Users] Basic Question / Concept

At this point I am considering using OpenSips & OpenSipsCP to run as a border controller per say.

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.


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.


Does this sound like something that will do the trick?


I would love to get a knowledgeable tech to jump in, I have a squeaky thin budget for someone interested, please contact me.
