Dear Benny, Long time back someone else also faced the same issue. In that you told that guy that its Re-Transmission instead of reregister. You asked to checked 200 OK response to check if server is changing expire time. In my case at server expire time is set as 3600 and in 200 OK also server is returning 3600. What could be the issue?

If i set cfg.reg_timeout = 300 (Which is default), everything works fine. But if i change this alue to 3600 (I have to do it coz i am getting "Interval too small" from server with 300), It starts sending registration every second. It sends reregistrations even if it receives 200 OK. I am not sure why its happening. Any Idea?
