All circuits busy, problem with NAT.

hi guys, i run trixbox and i have a problem with using voipuser to call out and receive calls.

i have a potential solution by adding the NAT block to the config files, that allows me to make the call but every extension and other trunk on the PBX has audio silence, or if i dont add the NAT block then i can use my other trunks and extensions but not use voipuser as a trunk. When i try and make the call i just get a busy error.

I have identified the cause to be a regestration error as the machine has sent teh request but not received an answer.

But when i have NAT infomation (my potential solution) entered the account registers and logs in ok.

Config for that trunk is

And there is nothing unusual on the console output in debug mode,

what appears to be the problem?
