Thanks for that.

Actually, my machine has both an internal IP and a real IP address, so 
I didn't think I would need to turn on the NAT settings. But, stupidly, 
I set the binding interface of SIP to my internal address only - which 
probably explains my problems. I have now changed the binding back to 
0.0.0.0 and all is working.

(Well... the 'logging on' part anyway - i'm still having call problems 
bridging calls with an SIP phone, but that's another matter....)

Thanks again!
