Hello,

UAC sends INVITE to UAS, authorization procedure is required, therefore UAS responds with an 407 error code. At this point, the client does not respond with ACK, but the server does not send retransmits.
Is this the expected behavior?
* UAC -- SIPp, UAS -- Kamailio.

Can the Kamailio be configured to send 407 code retransmissions?

Thanks!
