Hi Kristian,
I will look into your pcaps this weekend. One point to look out for in the
meantime.
Make sure that the "contact" can be found for the subscribe. The 403 is
issued because we cannot find a contact based on the SUBSCRIBE message.
depending on your cfg, usrloc will try to use contact header, via and/or
received IPs and ports to locate your contact. This is a 'workaround' in
the absence of ipsec which uniquely identifies each UE connection.
Can you also, please send your cfg file as well as the log file when you
get the 403.
Cheers
Jason

Dear Kristian,
Just take a look at the value you have at "Auth Lifetime" or "Session
Timeout" AVPs on AAR request from P-CSCF through PCRF. Those are (afaik)
Base Diameter AVPs. Those values are referring to a timeout to cleanup the
diameter session. It seems like, when this timer will expire, the session
will be cleaned up together with the infos in usrloc.
This way, P-CSCF receives a packet from an UE which is basically unknown,
so the request will be dropped and an error will be sent out.
So, in theory, this value should be much more than the re-registration of
the client itself.
Anyway, i am only guessing because i haven't still completely addressed
the problem
Best,

Hi,
I have installed Kamailio version 4.4.1. Everything works just fine. If
I connect a PCRF via Rx to the P-CSCF, the registration still runs
through as expected but the subsequent SUBSCRIBE is rejected with "403
Forbidden - You must register first with a S-CSCF" error cause or is
simply ignored (see attached wireshark traces).
And, if I disconnect Rx and restart the P-CSCF, the "forbidden" problem
still persists. (But I can work around this by cleaning up the P-CSCF
database.)
Any suggestions how I could get Rx working?
Thanks,
Kristian
