Hi, I had posted this query to the SIP implementors mailing list . So for those who have not read this let me summarise the problem.
"I wanted to know if there is a mechanism where registration information could be shared among SIP proxies.wrt to SER . This is helpful in a farm that is being loadbalanced.
The topology is a vserver that has two SER proxies S1 and S2 on UDP.
A client 'A' sends a register request to the loadbalancer vip/vserver and the load balancer chooses a service S1 tied on the vip/vserver . The client is registered at the server S1. Now a new call comes for this client, hits the vip and the call hashes to the other service S2 bound to the vip. If S1 and S2 are not sharing the same DB or are not talking to the same registrar we will have a problem. "
As a solution Dale R. Worley from pingtel suggested that A SIP registrar can actively duplicate its information into another SIP registrar by doing third-party REGISTERs to it .
So my question is how do I set up this third party Registration mechanism in SER so that a client registers with one proxy and inturn the proxy transfers this registration info to other participating proxies?
thanks, sandeep
