[OpenSBC] openser + opensbc as nat

[vics <vic...@gm...>]

Hi,


 I have an openser + mediaproxy server, I want to use opensbc to be my Nat server that handles my RTP stream , because mediaproxy proxyes everything, it does not have P2P stream like in asterisk canreinvite, but may be any one have done it before, and if so please give a clue..


 


Thanks so much..

OpenSBC default behavior is to only proxy NAT when the call comes from a private address or is terminating to one.   There is no need for a reINVITE to have media flow directly between UA for public-IP calls.  Your question is not obvious but I suppose you are asking if you could replace media proxy with OpenSBC?   Then the answer to that is yes.

Hi, 


is opensbc stable enough to put it in a production environment? I mean to handle thousands of call streams, and do you know any how on how to get it done?


 


Thanks so much..

OpenSBC is being used in stable production environments by several service providers that we know of.  At Solegy alone, OpenSBC handles transactions for hundreds of thousands of end users and processes millions of call attempts daily.  The capacity of a single instance will vary depending on your usage scenario, however you can expect an instance running on an avaerage server (in B2BUA mode with media proxy enabled) to handle several hundred concurrent calls and many thousands of registered users.  Higher capacities may be achieved by using load-balancing techniques.


If you are interested in a commrcial support arrangement from the people that created OpenSBC, Solegy offers several options check here:

On your question regarding NAT, OpenSBC is designed to have a public IP address on at least one network interface.  It is possible to use OpenSBC as a bridge between public and private networks, but it is not possible (at least not currently) for OpenSBC to communicate with UAs on the public Internet if it is behind NAT.
