SIP proxy stateless or stateful question

Currently we are running SIP dispatcher (kamailio) stateless for SIP load-load balancing and we are planning to replace it with BIG-IP F5 load-balancer now question is how does F5 use stateful or stateless transaction because we have very high volume SIP traffic and i don't want to overload F5 with sip transactions, all i want it just route SIP messages and forget about it, don't track of transaction. any idea?

    Hi Satish,

     

    F5 does not maintain any SIP transactions (F5 is stateless). F5 can maintain persistence or stickyness to send all subsequent request with same call-id to same proxy server.

     

    Thanks

    Thanks for you reply! We have very high volume sip traffic so I was worried if it hold transaction or dialogs in memory then it will be big problem in F5
