[OpenSIPS-Users] new install and INVITES not being forwarded

[Bogdan-Andrei Iancu]

Hi Gareth,

On a first look, the script looks ok, but as a general way to 
debug/troubleshoot your script, place xlog()'s in your script, in 
different points, to see if the script execution gets to that point.

Regarding the 408 - take care your script does not have NAT support, so 
it may not work if your client is behind a NAT.

Regards,
Bogdan
