[Asterisk-Users] empty username in authorization section ?!

[Dawid Mielnik]

Hi all,


Why does asterisk send empty username in authorization section ?

 

My setup is as follows:

 

SIP UA(x-lite) ------ ASTERISK ------ SER ------ 

 

I am trying to have asterisk route calls to a sip proxy. The sip proxy
requires authorization on calls to pstn. The problem is that asterisk sends
an empty username in the Authorization section (INVITE message) in response
to the Unauthorized challenge message sent by proxy: 

 

Authorization: Digest username="", realm="myrealm", algorithm=MD5,
uri="sip:0501657887 at myrealm

 

 

Below is the configuration info and the full sip debug.

 

Thanks,

 

Dave
