Summary:                    "auth" doesn't work inside a [peer]
Description: 
I define a peer who needs authentication to accept calls form my Asterisk:

---sip.conf---
[peer-cdr]
type=peer
host=cdr.mydomain.org
fromuser=991847150
fromdomain=mydomain.org
auth=user51:1234 at mydomain.org
insecure=invite
qualify=no
nat=no
canreinvite=no
-------------

But it fails when Asterisk sends an INVITE to that peer. In fact, I think
the "auth" parameter inside [peer] is not parsed at all. Note in the
attached debug that after "407 Authentication required" there is not a new
INVITE from Asterisk.


But if I move the line:
  auth=user51:1234 at cdr.mydomain.org
to [authentication] section then it works!  ¿?¿

---sip.conf---
[authentication]
auth=user51:1234 at cdr.mydomain.org
--------------

Note the comment in [authentication] section:
  ; You may also add auth= statements to [peer] definitions 
  ; Peer auth= override all other authentication settings if we match on
realm

So something is buggy here IMHO.


Of course, another solution would be using "username" and "secret", but
why should I write the password in clear?

---sip.conf---
[peer-cdr]
type=peer
host=cdr.mydomain.org
fromuser=991847150
fromdomain=mydomain.org
username=user51
secret=1234
insecure=invite
qualify=no
nat=no
canreinvite=no
-------------


And remember that using "auth" in [authentication] is a risk (bug
