Does your NAT gateway have some inbuilt SIP feature? For example - a SIP ALG on it? If yes, try disabling it.
Also check if you have set any port forwarding rule on your NAT gateway for port 5060.

Great!!
this actually worked. I've changed the port from 5060 to 5070 and now authorization runs fine. Could anyone give a logical explanation for this?
thanks again Mike, Bart

Hello Bart,
Looks like UA not receiving 401 unauthorized message from
SER, that's
why it not resend REGISTER message with calculated digest. Maybe you have some troubles with NAT on 213.219.137.148?
Hint: use ngrep with -W byline option (eg: ngrep -W byline
port 5060
)

One thing... some routers think that they are very smart :), so try to change port on SER from 5060 to some other ( like: port=5070 ) most of routers can be fooled with it.
