[OpenSER-Users] mirror proxy/upstream Registrar - sr-users

9 Jun 2008

Hi

Thanks for your reply.

Yes in fact, the registrar is some sort of a billing application that enforce AAA. 

The only problem is , it does not handle NAT traversal. That's why we need OpenSer to
act as an SBC.

  Hello,

 We would like to evaluate OpenSER to test interoperability with our
 sip registrar platform - as our registrar does not handle NAT Traversal
 we would like to use OpenSER as a mirror proxy . Basically we would like
 OpenSER to act as an Upper Registrar proxy where all the sip messages would
 be forwarded to our registrar, based on the domain name used in the
 Register. ie: REGISTER 111 at domain1.com  -> forward to -> registrar_ip1
 REGISTER 222 at domain2.com -> forward to -> registrar_ip2
 and so on... 
Take a look to "t_replicate" function of "tm" module.

...
  If a call is initiated, OpenSER should transparently
handle NAT traversal
 functionalities while forwarding the INVITE request to the proper registrar
 server. 
Do you mean that an INVITE should be forwarded to a registrar server? maybe 
the registrar is also a proxy/PBX?

Please, explain a little more your escenario.

Regards.
