Hi Alex,
Thanks for the response.
No understood, I am aware kamailio is all about thousands of calls per second, I just wondered if it had been bench marked, as many companies unfamiliar with kamailio like these things :).
I will look at it from the database angle as there will be the same amount of queries.
thanks
Jon
