Anyone use Gamma Telecom

[Jimbo_]

Hi,

I have an issue with our new SIP Trunk provided through Gamma Telecom. Incoming calls are working like a dream but outgoing calls are coming back with:
[CM503020]: Call(C:56): Normal call termination. Call originator: Extn:100. Reason: Forbidden

I did have it working but had to rebuild our 3CX after some server changes so started from scratch again and now I'm getting this.

Any ideas are welcome!

Thanks

Jimbo

Cancel that, it was a NAT issue on the router.
