[Ludovic DURAND]

Hi, 



The purpose of projet is to implement a VoIP secure solution with Kamailio as core IMS network. 
In this project VoIP call will be established with zRTP. SBC is transparent for zRTP call, zRTP is establish between 2 end point (terminals), SBC don't decrypt or encrypt the call. Thus SBC don't modify codec. 
Is there a SBC solution provided by Kamailio ? 





How is managed the SBC failover mecanism ? is there SBC backup ? 
What is the status of context registered in Kamailio (P-CSCF & S-CSCF) in case of SBC failure ? 

- Is it deleted automatically ? 

- dispatched to another SBC (backup SBC) ? 





Is there mecanism in Kamailio to check SBC overload and manage a dispatching of zRTP call to available SBC ? 




Question related to P-CSCF and S-CSCF : 
- Is there redundant function (such as active/active or active/standby solution) of contextual data (customer data stored at the registration REGISTER on P-CSCF and S-CSCF) ? 

Best Regards
