[SR-Users] Kamailio 5.3.0 and HEPv3 oversized traffic

[Karsten Horsmann]

Hi Sergiu,

thanks for pointing that out. I tried kamailio 5.3.4 with the settings
below.
Works now. I see the answers of kamailio itself.

Unfortunately my UAC input messages are now doubled in homer.
Will check that tomorrow.

And for fun - with sip_trace i can send to more than one target, nice.

#!ifdef WITH_HOMER
        # start duplicate the SIP message here
        sip_trace();
        # address - The address in form of SIP URI where to send a
duplicate of traced message.
        sip_trace("sip:127.0.0.1:9060");
        sip_trace_mode("t");

        #setflag(22);
#!endif


modparam("siptrace", "force_send_sock", "MY_LOCAL_SENDSOCK")
modparam("siptrace", "duplicate_uri", "MY_HOMER_CAPTURE")
modparam("siptrace", "hep_mode_on", 1)
modparam("siptrace", "hep_version", 3)
modparam("siptrace", "trace_to_database", 0)
##modparam("siptrace", "trace_flag", 22)
modparam("siptrace", "trace_on", 1)
modparam("siptrace", "trace_mode", 3)
modparam("siptrace", "hep_capture_id", MY_HEP_NODE_ID)

Cheers
