Summary:                    [patch] Wrong uri in the authentication header
Description: 
I just tried to send a call via callcentric.com from asterisk 1.8.3 box.
During the password check is seems to send a wrong URI - skipping the user
part. For example, the packet sent out was:

-----
INVITE sip:17771234567 at callcentric.com SIP/2.0.
...
Proxy-Authorization: Digest username="17772777xxx",
realm="callcentric.com", algorithm=MD5, uri="sip:callcentric.com",
nonce="xxxxxxxxxxxxxxxxxxxxxxxxxx", response="xxxxxxxxxxxxxxxxxxxxxxxxxx".
-----

While according to the RFC3261 (22.4 step 3), it should be the request
uri, so "sip:17771234567 at callcentric.com".

---------------------------------------------------------------------- 
Attached patch fixes the issue for invites... I'm not sure what else could
be affected here. I switched the cases around to prefer uri over domain,
but I'm not even sure why a situation without uri would ever occur.
If it does, this might cause some other issues.
