Hi all,
Once again, thank you all for the Help.
I have one last question, can I use the function Rx_AAR_Register without
save the usr location information on ims_usrloc_pcscf? that is because
I'm already using the usrloc module with dmq_usrloc.
I know that ims_usrloc_pcscf is a dependency of ims_qos, but the doubt here
is if I don't use the ims_registrar_pcscf, the usrloc_pcscf won't be used
to store usr location? And the ims_qos will works correctly?

Hi Jason,
It is always better when code "guru" shares his opinion :)
Cheers gents !

Hi gents,
we do not support the preliminary service information. So for now you can
only call Rx_AAR when you have SDP in the replies. So for VoLTE
(preconditions), for example you can call on 183 SP whilst using plain SIP
you will have to call on the first reply you get that has SDP (either 183SP
or 200OK).

Yes you send both direction media information to
the PCRF but when reply
is received in precondition state.

Hello Ivailo and Franz,
Thank you for your clarifications.
Well sending an AAR when receive a reply makes all sense, but ims_qos
must send the SDP information from the Initial Invite and also from 183
ringing or 200Ok, Am I correct?
Because PCRF needs to know the session parameters from Initial Initial
INVITE and the reply to it.
The PCRF is a proprietary solution.
Thank you

Hi Franz,
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.
Cheers,
Ivo

Hi José,
in principle it is possible to send an AAR after receiving the request.
In this case the Service-Info-Status AVP is set to PRELIMINARY SERVICE
INFORMATION.
More efficient is it to wait until SDP answer is received and then the
Service-Info-Status AVP is set to FINAL_SERVICE_INFORMATION.
I don’t know if both methods are covered in ims_qos module.
BTW: which PCRF are you using? Is there some open source PCRF available?

*Subject:* [SR-Users] Kamailio IMS_QOS
Hello There,
I'm trying using the ims_qos module with PCRF for QOS, but I'm facing
some issues.
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:
5(12153) DEBUG: <script>: Diameter: Orig authorizing media via Rx
5(12153) DEBUG: ims_qos [mod.c:609]: w_rx_aar(): Looking for route
block [ORIG_SESSION_AAR]
5(12153) DEBUG: ims_qos [mod.c:621]: w_rx_aar(): Rx AAR called
5(12153) DEBUG: ims_qos [mod.c:1345]: create_return_code(): Creating
return code of [-2] for aar_return_code
5(12153) DEBUG: ims_qos [mod.c:1354]: create_return_code(): created AVP
successfully : [aar_return_code]
5(12153) DEBUG: ims_qos [mod.c:627]: w_rx_aar(): Can't do AAR for call
session in request.
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:
//We don't ever do AAR on request for calling scenario...
if (msg->first_line.type != SIP_REPLY) {
LM_DBG("Can't do AAR for call session in request\n");
return result;
}
Anyone can help me understand why it is happening? why it can't proceed
if isn't a reply?
Thank you for your support
BR
