Hello,

 

       I wrote a H.323/SIP IWF program before, it was based on B2BUA framework. Currently I am planning to

use Kamailio as internal routing server and let IWF become a class 4 soft switch.That is

       Inbound ---- H.323/ SIP -- >                    ---- SIP routing request-----> Kamailio

                                               IWF/SBC                                              |

       Outbound <--- H.323/SIP --                   <--- SIP -----------------------------

 

      Is it ok to store all voip provider's information at database of Kamailio and pass all to IWF at private SIP headers and let IWF as a outbound proxy?

      Is Kamailio as a SIP redirect server or it is better to stay at call signaling path until call session ended?

 

      It is great to share any information about this.

 

regards,

Gang
