Hi Mates,I am testing a Client in Nokia E65 using kamailio 1.3.3. I managed
to successfull get it Registered but when i attempt to make a call i always
get the "404 Not Found" message in the INVITE. Strangely enough, the Client
appears to still be ONLINE in the location table.

Hi Mates,

the "404 Not Found" message in the INVITE. Strangely enough, the Client

Your conclusion is wrong. A user doen't need to be registered in order
to make a PSTN call (except if you add that logic to your script, that
is not the case).
So, forget yuor user is registered, it's doesn't matter, and debug why
your dialed number is not matched as a number to the PSTN.

Iñaki is right here.
In addition, "404 Not Found" is not the correct reponse when the
destination target is not registered, IMO it should be a 480 instead.

Yeah!!!
404 should be returned when the proxy/UAS received a request and it's
not responsible for it, for example a non existing user (non existing
user != non registered user).
When a user is not registered, but it does exist in the server, the
server must reply "480".
