You should send a pcap file with all packets, from first incoming
INVITE to kamailio. It is important to have both sides of signaling
from kamailio point of view, from first packet in that call.<br>

AboutAsteirsk and Kamailio I think As Daniel that Auth is not
Asterisk problem.

My problem with last ACK, that I send to
provider. Provider ignores it, and sends me
some OK packets. As resultI can notend session
( answer to BYE 481 - transaction does not
exists). I think it is wrong ACK but can not
undrtand where I do mistake.<br>

Well, by letting the proxy handle authentication the
INVITE tranction i closed without Asterisk knowing
about it. So the ACK sent from the proxy and from
Asterisk is for the same transaction, which messes
things up. Asterisk does not know anything about the
second invite. Letting the proxy handle
authentiction breaks the SIP protocol in bad ways
and is generally not a good solution.</div>
<div>You may want to send another response to asterisk
when you get the 407 so Asterisk retries and use the
retry as a trigger for the second INVITE and add
auth to that.</div>
</blockquote>
</div>
While breaking the cseq incrementation for authentication
(mentioned in the readme of uac), the Asterisk seems to do
ok here, because the ACK is coming from asterisk, but it
is not accepted by the provider.<br>
<br>
The provider (having a plivo platform, based on the
responses) is running kamailio 4.1.2 in front (looking at
100 trying).<br>
<br>
Authentication from kamailio to another kamailio using uac
module should work fine, as kamailio doesn't act as end
user UAC and doesn't care much of cseq.<br>
<br>
I didn't have time to look at the sip trace properly, but
Asterisk should have nothing to do with the problem here,
unless I missed something from the description.<br>
<br>
