Cleaning up a few errors and warning

[Aaron M]

I have my IPsec VPN working. I can connect from both my iPhone and my laptop. So as far as working, it seems to be ok. I just want to "fix" a few errors I'm seeing in the logs. I'm not sure that anything is wrong, but I just personally don't like seeing them. There are a ton of references to these errors via Google, but I have yet to find a solution.

ERROR: notification INITIAL-CONTACT received in aggressive exchange.

I am having the same issue as well, is there anyway to find out why are these errors are showing up ? I have some difficulty connecting my phone to a SIP registrar server over VPN . sometimes it registers and others it says request time out !
