[SR-Users] UACREG - answering to 401 on invite

[Jean Cérien]

Thanks - I've done some progress - I've hard coded temporarily the user,
pass & realm, and authentication goes out now.

However, the provider is answering with a 401 & a new nonce.

here is what I have

INVITE --->
<---- 401 (with nonce)
ACK --->
INVITE ---> with correct nonce & response, I've recalculated the response,
it is ok
<--- 401 (with new nonce)
ACK -->

When I configure another box with a plain asterisk and same credentials,
the call goes through fine - so it is not because my ip is wrong or not
whitelisted.

Why would the remote send me a 401 ??? I've tried to contact them but no
answer

J.
