Hi Franz,<br>
<br>
There no real OS PCRF. Yota/Telexir use to had some free VM image
that is OK for test. You can search about FreePCRF. It is a little
tricky to configure it but ... I made for my tests a really dummy
one based on FreeDIAMETER. Generally speaking PCRF is the "brain" of
the network and you should understand and design things well there.
I have experience also w/ commercial PCRFs and there is no real
answer yes this is a right way of making something.<br>
<br>
Cheers,<br>
<br>
Ivo<br>

<p class="MsoNormal">Hello There,<br>
<br>
I'm trying using the ims_qos module with PCRF for
QOS, but I'm facing some issues.<br>
<br>
When kamailio receives an initial invite
(originator), it will execute the function -
"Rx_AAR("ORIG_SESSION_AAR","orig","",-1)", but the
PCRF is not contacted and i see the following
messages:<br>
<br>
5(12153) DEBUG: <script>: Diameter: Orig
authorizing media via Rx<br>
5(12153) DEBUG: ims_qos [mod.c:609]: w_rx_aar():

5(12153) DEBUG: ims_qos [mod.c:621]: w_rx_aar(): Rx

<br clear="all">
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Why
kamailio says that I Can't do AAR for call session
in request? I have looked into source code and I
found that the condition that is blocking the
communication with PCRF is:<br>
<br>
<br>
<br>
<br>
<br>
//We don't ever do AAR on request for calling
scenario...<br>
if (msg->first_line.type != SIP_REPLY) {<br>
LM_DBG("Can't do AAR for call session in
request\n");<br>
return result;<br>
}<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Anyone
can help me understand why it is happening? why it can't
proceed if isn't a reply?<o:p></o:p></p>
