Hi Shravan,

 

Your first steps would be here: https://www.kamailio.org/docs/modules/devel/modules/sctp.html

 

If you are not sure how to get SCTP working in your Kamailio you can reference this article that should get you started - https://nickvsnetworking.com/kamailio-bytes-sctp/

 

Then configure multihoming within your network.  

 

Personally, I would setup and test the multi-homing first before adding the module to confirm it works and the logic does what you need it to do. In my experience I have used the source address groups against the address.list for inbound and a dispatcher.list for outbound to route traffic.

 

Your mileage may vary on how easy/complex your setup/logic is.

 

Thanks,

 

John.
