<div dir="ltr">All packets (INVITE,ACK,BYE) that comes from Asterisk and sends to Provider handled by Kamailio (changed tU, fU and td and from d). so I write to PLIVO this question, but they still answer to me nothing... As I see my trace there are no simple muistakes (such as wrong dst or wrong contact header).<br>
<br>AboutAsteirsk and Kamailio I think As Daniel that Auth is not Asterisk problem. <table class="" style="border-spacing:0px;color:rgb(119,119,119);font-family:arial,sans-serif;font-size:13px"><tbody><tr><td colspan="2" style="padding:0px">

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>
