[SR-Users] Kamailio IMS_QOS

Hi Jason,
What could be the impact of using both modules (usrloc and
ims_usrloc_pcscf)?
One of the impacts that I can see is the Shared memory, it will consume
more shared memory because will save the AOR twice in memory, one in
usrloc and the other in ims_usrloc_pcscf, is that right?
Another Doubt that I have:
At this moment I'm only using the function rx_aar, (I'm not using ims_qos
with register sip messages), and when kamailio sends an AAR to PCRF, the
AVP "Flow-Description" contains the IP address of received host, that is a
kamailio server acting as loadbalancer, not the Terminal IP address.
So I'm obliged to use RX on registrar messages in order to have the AOR of
the SIP Terminal on the AVP "Flow-Description"? Or can I manipulate it in
an easy way?
Anyway I'm facing an issue when PCRF is sending an Abort-Session Request
after the call is established, Kamailio stops working with the following
