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

[Gareth Blades]

I installed a caching nameserver but it made no difference.
I then switched logging from syslog to stderr and thats much better and 
the phone can register fine.
I have attached the debug from when I tried making the call between 
lines. If there is nothing usefull there then can you let me know where 
I could put some additional loggin in the config file in order to help.

Thanks
