Yes, here is two INVITEs (I have missed first invite before), but the server 
respond 401 on first invite and softphone send ACK. Here is softphone log. 
Unfortunately, I do not know how to enable (where to find) log of SIP 
messages at server?

I have find one more issue, the server sends two replies on register 
message, first with 200 and second one 403 with same CSeq. I am not sure is 
that relayted to INVITE issue. But the asterisk show user as 
connected-unmonitored in control panel (trixbox).

Best regards,
