Then you use just "username".

I don't think the MD5 is critical - the auth=username:password at domain is
what chan_sip2 uses.

You must not use port=5060 in sip.conf - it has to be port=5052. You also
have to do funny things with the externip - point it to the *internal*
address and use "nat=yes" as per my example. It seems to need to think it is
coming via NAT. Otherwise it may register and fail the second
proxy_auth_required. It is all very strange.

If you change the username.brz in my example to your username (as seen by
ethereal) and normal password and give that a try.

Also note the fact that btinternet.com and sip.btcommunicator.net can not be
used interchangeably and it is fussy which is used where.

I put a "81.144.106.4    btinternet.com" line into my /etc/hosts file. This
is the address of sip.btcommunicator.bt.net. But if you put
host=sip.btcommunicator.bt.net into the sip.conf file, authentication fails.
Put a host=btinternet.com in sip.conf which will then connect to the right
machine using the wrong name and this works! The implementaion of domains
and servers seems a bit odd.

Hi Peter, just a couple of quick questions

if the my ethereal trace only shows {username}@btinternet.com  do I need 
the .brz?

is the MD5sum in the ethereal trace, as I have compared all combinations 
of MD5sum with the ethereal trace and cannot see it any where?

Still cannot register, any advice would be greatly appreciated

Regards

Robb
