Certainly.. Here's one I made earlier. Can do a more up to date and in depth one if you want more.

Hi gang,

Got a strange problem with a NAT'd device that's trying to connect to
FS. The first REGISTER arrives, without auth, and FS responds with 401
Unauthorized to the correct port on the external IP address of the
firewall. However when the second attempt to REGISTER, this time with
auth, comes in, FS responds with 200 OK to the local SIP port
specified on the device. The device obviously doesn't get the 200 OK
so keeps attempting to register.

Any ideas? Tried sip-force-contact but that doesn't seem to help.
