[SR-Users] cdp avps issues in kamailio 5.2

[Pavel S]

Hello Mojtava,

> Did you use FHOSS or IMS_DIAMETER_SERVER module?
No, I am using our own hss server.

>Anyway what mandatory parameters do you mean exactly?
According to RFC6733 section 5.3.1 -
https://tools.ietf.org/html/rfc6733#section-5.3.1

   The Capabilities-Exchange-Request (CER), indicated by the Command
   Code set to 257 and the Command Flags' 'R' bit set, is sent to
   exchange local capabilities.  Upon detection of a transport failure,
   this message MUST NOT be sent to an alternate peer.

   When Diameter is run over SCTP [RFC4960] or DTLS/SCTP [RFC6083],
   which allow for connections to span multiple interfaces and multiple
   IP addresses, the Capabilities-Exchange-Request message MUST contain
   one Host-IP-Address AVP for each potential IP address that MAY be
   locally used when transmitting Diameter messages.

      Message Format

         <CER> ::= < Diameter Header: 257, REQ >
                   { Origin-Host }
                   { Origin-Realm }
                1* { Host-IP-Address }
                   { Vendor-Id }
                   { Product-Name }
                   [ Origin-State-Id ]
                 * [ Supported-Vendor-Id ]
                 * [ Auth-Application-Id ]
                 * [ Inband-Security-Id ]
                 * [ Acct-Application-Id ]
                 * [ Vendor-Specific-Application-Id ]
                   [ Firmware-Revision ]
                 * [ AVP ]

Kamailio 5.1 with loaded cdp, cdr_avp, ims_icsf modules and default
configuration described here
https://github.com/kamailio/kamailio/tree/master/misc/examples/ims/icscf
sends Host-IP-Address but Kamailio 5.2 with the same configuration
doesn't.

Any idea how to fix it?

Pavel Siderov
