Hi Jan,
In the NOTIFY message, it has a proxy authentication nonce got from REGISTER messages.
I am not in the <some test here> if proxy_authorize() should be called and the impact on the ser performance.

Since the purpose of NOTIFY messages is just to get some reply from SER and keep the NAT bindings open, I would recommend to put a simple test at the beginning of the configuration file and send 200 OK immediately, something like:
if (method == "NOTIFY" && <some test here>) { sl_send_reply("200", "OK"); break; };
Note that you have to replace <some test here> with something that tests if this is one of the NOTIFYs keeping the NAT open, you could probably test for some particular value in the Request-URI, or something like that. You probably do not want to reply all NOTIFY messages this way.
Jan.
