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
