<p>Hello,</p>
<p>Kamailio is not generating the 200ok for INVITE (calls), it just
sends out what it received from end point, after consuming own Via
header (of course, other headers can be changed based on config
rules, but Kamailio is not in charge of setting To-tag).</p>
<p>Cheers,<br>
Daniel<br>

<p class="MsoNormal">SIP/UE (boghe or imsdroid) client
registered to Kamailio makes call to an Asterisk registered
SIP phone is successful:<o:p></o:p></p>
<p class="MsoNormal">[UE]-Kamailio--->INVITE--->Asterisk16-[phone]<o:p></o:p></p>
<p class="MsoNormal">[UE]-Kamailio--->200 OK with
to_tag--->Asterisk16-[phone]<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But in reverse direction for a call,
Kamailio does not return the SIP OK so no to_tag is sent so
call fails to ring and complete:<o:p></o:p></p>
<p class="MsoNormal">[phone]-Asterisk16
--->INVITE--->Kamailio<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Where the UE device never receives the
INVITE, Asterisk never gets and 200 OK message with the to_tag
from the I-CSCF, the call flow itself gets lost in Kamailio,
where the P-CSCF sends final INVITE to I-CSCF and and
ultimately a 604 HSS user unknown message is sent back to
Asterisk from the I-CSCF.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Basically Im using the default “sample”
configs for both the P and the I-CSCF. Our sauce is in the
S-CSCF for out going calls that originate by a registered UE.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any insight or sample Kamailio
configuration that Im lacking?
<o:p></o:p></p>
<p class="MsoNormal">Has anyone done this and could share the
asterisk and Kamailio script snippets that make it possible.<o:p></o:p></p>
