[Sems] di_dial and auth

[Andreas Granig]

Hi,

I'm currently playing around with xmlrpc2di and di_dial, and I can't get 
my SEMS to authenticate at the server. Scenario is:

[SEMS] - [SER for SEMS at 127.0.0.1] - [OpenSER at 127.0.0.1 and LAN]

In my python-cli I have:

 >>> s.dial_auth("announcement", "default_en", "sip:test1 at 127.0.0.1", 
"sip:test2 at 127.0.0.1", "127.0.0.1", "test1", "foobar")

The first INVITE reaches my OpenSER, but it replies with "407 Proxy 
Auth". At this point, no more INVITE with credentials is being sent by 
OpenSER (at least none is seen on the net). SEMS logs this:

Any hints are very much appreciated.
