[asterisk-users] Asterisk refuses INVITE (401) and I don't know why

[Alex Vishnev]

I doubt it. Unknown headers should be ignored by UAS. is it possible to post the trace?

If Invite is challenged and the peer responds with the correctly calculated NONCE, domain and other Auth params, then something is wrong with your Authentication. I suggest trapping the traffic with Ethereal or any other packet capture programs and examining that carefully from the start of the session (i.e. register) to the invite. I would also check where the 401 is coming from (i.e. IP address).
