Thanks Brian

'Contact:' is as follows

UDP-NAT phones
"" 
<sip:1002 at 192.168.0.111:5060;fs_nat=yes;fs_path=sip%3A1002%40xxx.xxx.xx.xxx%3A5060>

UDP phones
"" <sip:1000 at xxx.xx.xxx.xxx:5060>

(public ip addresses removed for security)

What does that mean as I am not familiar with the internals for FS?

Thanks
Dion.
