[SR-Users] REGISTER OK but on send "407 Proxy Authentication Required" with no ACK

[Andrew Pogrebennyk]

Hello,
I see no problem with an ACK in the trace. The t38modem ACK's the 407,
sends the new INVITE with authorization but it's not accepted by
kamailio. I'm not sure if t38modem can even perform the authorization.
Maybe you need to accept the calls from it without authorization. But if
it can and you have configured the password in there, you should check
that the subscriber 979 exist in kamailio domain 10.1.1.148 and the
passwords do match.
