Registration of the SIP PEER is no problem. The PEER registers with a 
correct REGISTER statement and Asterisk sends a 200 OK.

So the PEER is registered and then wants to make a call (INVITE) but for 
some reason this INVITE is being refused with 401-Unauthorized.

The first 401-Unauthorized is normal, because the SIP PEER needs to send 
a second INVITE with a challenge (nonce). But after this INVITE with 
challenge, Asterisk still sends a 401 and that's strange !!
